◆Customer Issues◆ - We received complaints about weeds from the slope encroaching into the rice fields at the bottom of the slope. - Weeds on the shoulder were also encroaching onto the sidewalk, obstructing pedestrian passage. ◆Points for Sheet Selection◆ - Due to strong winds blowing down from the mountains and the nature of the slope, there were concerns about the sheets being blown away. Therefore, we selected a heavy McLean Sheet®. - To ensure the sheets are securely fixed, we used longer L-shaped anchor pins, φ9mm×300mm. - To suppress weeds from the base of the support posts, we used a weed prevention rubber coat. ◆Customer Feedback◆ - There has been no issue with the sheets being blown away by the wind, and after three years since installation, they are effectively suppressing weeds. - Weeds on the sidewalk have also been controlled, allowing pedestrians to pass safely. - Weed prevention measures have been thoroughly implemented up to the base of the posts, maintaining the landscape.

As a measure against weeds, weed control sheets are utilized in various locations. Particularly along roadsides, where the proliferation of weeds can obstruct the view of drivers and pedestrians, making it dangerous, weed control sheets are commonly used. In areas with snowfall, when introducing weed control sheets along the roadside, there is a risk that the snowplow's bucket may catch the edge of the sheet, or the tires may roll over the edge, causing the sheet to tear and lift. As a countermeasure, one method is to lay the weed control sheet before asphalt paving and cover the edges of the sheet with asphalt during the paving process. This is an example of using polyester weed control sheets, taking advantage of the property that polyester has a higher melting point than asphalt (approximately 260°C). *For detailed construction methods, please contact our company.

◆Customer Concerns◆ The slope next to the waterway. Since it faces residential areas and fields, regular grass cutting was being carried out. In some places, there were areas surrounded by fences or with steep inclines, making the work dangerous. In areas right next to the waterway, care was taken to ensure that the cut grass did not fall into the water, which made the work more labor-intensive. ◆Customer Feedback During Construction◆ - The sheet was soft and conformed to the uneven ground, making installation easier. It was also easier to handle the treatment of structures like concrete. - There were markers for the positions to install the pins, which shortened the work time.

◆Customer Issues◆ - We faced a risk of traffic accidents due to overgrown weeds near the intersection, which obstructed drivers' visibility. - Many complaints from citizens were received due to the overgrowth of weeds. We had to conduct grass cutting as a response to these complaints, resulting in management costs. ◆Points for Sheet Selection◆ - Since the customer desired a long-lasting weed control sheet, we proposed the high-durability weed control sheet "GU Sheet" with a 20-year lifespan. - To suppress weeds from the base of the posts, we suggested a "weed control rubber coat." ◆Customer Feedback◆ - The improvement in visibility within the intersection contributes to the traffic safety of citizens. - We used to conduct grass cutting 4 to 5 times a year as a response to complaints, but this will lead to cost reduction. - The weed control measures are effectively implemented up to the base of the posts, maintaining the landscape.

◆Customer's Issue◆ The weeds that had grown thickly along the slope by the prefectural road were falling onto the sidewalk and roadway, obstructing passage. Due to the slope, annual grass cutting was difficult and labor-intensive. ◆Points for Sheet Selection◆ - A highly flexible weed control sheet that adapts well to uneven surfaces - A weed control sheet with a long lifespan Since these were the customer's preferences, we proposed the "GU Sheet," a high-durability weed control sheet designed for 20 years. ◆Customer Feedback◆ By using long anchor pins (φ9mm×400mm), we were able to securely fix the sheet even in soil where the pins did not hold well. The sheet had printed markers for pin placement, eliminating the need for prior marking and saving time. Additionally, the sheet was soft and conformed well to the uneven ground, making installation easy.

◆Customer Concerns◆ - Weeds were overgrown on the sidewalk near a busy intersection, compromising safety. - Due to the high number of pedestrians, the overgrown weeds hindered walking, so we conducted mowing twice a year. ◆Points for Sheet Selection◆ - A highly flexible weed control sheet that adapts well to uneven surfaces. - Since a long lifespan was desired, we proposed the "GU Sheet," a highly durable weed control sheet with a 20-year lifespan. ◆Customer Feedback◆ - There is a wide variety of materials suitable for the installation site, such as "asphalt pins" for the asphalt edges and "simple U-shaped gutter clips" for the U-shaped gutters, making it easy to address even the finer details. - The sheet was very flexible, making installation easy.

The main cause of weed mat peeling is "wind entering from the edges of the mat." To prevent wind from getting underneath the weed mat, it is important to eliminate gaps at the edges of the mat. If the edges are against a concrete structure, you can use adhesive to seal the gaps, but in the case of bare ground, adhesive cannot be used. Therefore, we recommend using a "Hurricane Net" to secure the edges of the mat. The "Hurricane Net" is 455mm wide, allowing for a strong and secure attachment of the weed mat.

◆Customer Concerns◆ - When there are tall weeds near the road, there is a possibility of them hitting vehicles or causing traffic accidents due to poor visibility. - It is a hassle to outsource the annual grass cutting to a contractor. - Contractors may not be able to cut the grass immediately due to their other commitments. - Weeds with strong growth, such as goldenrod and vigorous grass species like barnyard grass, are present. ◆Customer Feedback After Installation◆ - Visibility has improved, eliminating the risk of traffic accidents due to poor sight! - Strong weeds are well controlled, so management is no longer necessary!

Weeds have crossed over the fence and invaded the roadway. Additionally, the entire fence is covered with weeds, resulting in poor visibility. ◆ Customer Concerns ◆ - Grass cutting needs to be done 2 to 3 times a year, incurring management costs. - Weeds entangled in the fence cannot be cut with a mower, requiring manual cutting or hand removal, which is labor-intensive. - Weeds wrapping around the fence lead to "decreased visibility" and "poor sightlines." Furthermore, it can hinder airflow, potentially damaging the fence itself. ◆ Customer Feedback After Installation ◆ - Weeds on the sheet can be easily peeled off, making grass cutting much easier! - Since a net has been installed, the vines no longer come out onto the roadway! (Reduction in complaints from local residents!) - Good visibility can be maintained for a long period! * The vine guard method includes a 10-year durability vine guard method and a 20-year durability high-durability vine guard method. The current site has installed the high-durability vine guard method.

The creeping vine weed, kudzu, has proliferated on the slope next to the residential land, invading the neighboring properties over the fence. When kudzu grows abundantly, it deteriorates the landscape and attracts insects, so frequent mowing was necessary. ◆ Customer's Concerns ◆ - Mowing was dangerous because the area was a slope. - Mowing needed to be done 2 to 3 times a year, incurring management costs. - Removing kudzu tangled in the fence was labor-intensive. - When kudzu wrapped around the fence, it obstructed visibility and airflow. ◆ Customer Feedback After Installation ◆ - In the year of installation, I didn't have to mow at all. The frequency significantly decreased in the following years! - The kudzu that grew on the sheet was easy to peel off, making mowing much simpler! - The visibility is always good, and it feels pleasant! * The vine guard method comes in two types: a 10-year durability vine guard method and a 20-year high-durability vine guard method. The current site has the vine guard method installed.

◆Customer Concerns◆ - When tall weeds grow from the sidewalk joints, the bus stop becomes hard to see, making it difficult for bus users to utilize it. - It obstructs pedestrian passage. ◆Customer Feedback After Work Completion◆ - The weeds are gone, and the bus stop is clearly visible from a distance! - There are no weeds obstructing passage, allowing for comfortable movement!

◆Customer's Concerns◆ - We were troubled by weeds growing from under the guardrail installed along the riverside road. When pedestrians passed by the roadside, the tall grass would brush against their legs, hindering their walking. There was also littering. - It was difficult to manage the weeds around the joints and posts because the grass cutter would hit them, making weed management challenging. ◆Customer Feedback After Construction◆ - Since the weeds are gone, we can now walk comfortably up to the roadside! There is no more littering. - With no need for grass cutting, managing the weeds has become much easier!

The Take Guard method is a revolutionary bamboo prevention technique that suppresses bamboo (bamboo shoots) from above using only a special sheet and dedicated pins. Bamboo (bamboo shoots) has such strong power that it can even break through asphalt. Can we really suppress such astonishing bamboo (bamboo shoots) lifting with just a sheet and pins? We will introduce the site of the "Take Guard method" in chronological order.

◆Customer's Concerns - The bamboo is growing excessively, making it difficult to manage. - The bamboo is tall, and when it falls, it can hit high vehicles like trucks and buses, leading to complaints. Additionally, there are areas touching power lines, creating a very dangerous situation. - Weeds are also growing so thickly that they cover the guardrails. ◆Customer Feedback After Construction - The danger from fallen bamboo has been reduced! - After observing the growth period of the bamboo, I want to expand the work to a wider area! - The weeds near the guardrails are being effectively controlled, reducing visibility issues for drivers!

◆Customer Concerns◆ - When constructing a new residential area, weeds are growing in the planting strip, making it look unappealing. - Even if plants are planted, they are difficult to manage. ◆Customer Feedback After Construction◆ - The weeds are gone, and it looks much better! - The surface of the sheet is smooth, so dust and dirt do not accumulate easily, and it is permeable, preventing puddles, which is great!

◆Customer Concerns◆ - Weeds are overgrown on the sidewalk, obstructing passage. - Tall weeds are flourishing along the edge of the sidewalk, making it difficult for drivers to see pedestrians. This is particularly dangerous near intersections, where the risk of traffic accidents is high. ◆Customer Feedback After Construction◆ - The weeds are well controlled, making the sidewalk wider and easier to pass! - It is now much easier to see pedestrians, reducing the risk of traffic accidents!

◆Customer Concerns◆ - Weeds are overgrown in the central divider, making it difficult to see oncoming traffic. - Weeds hit the car while driving. ◆Customer Feedback After Construction◆ - The weeds are well controlled, resulting in good visibility while driving! - There is no longer a need to avoid weeds while driving, reducing the risk of accidents!

◆Customer Concerns◆ - We received a safety concern from the police due to overgrown weeds at an intersection without traffic signals, which obstructs visibility. - We contract grass cutting every year, but the grass grows back quickly, necessitating frequent weeding, which incurs additional costs. ◆Customer Feedback After Construction◆ - Visibility has improved, eliminating the risk of traffic accidents! - We implemented effective weed control around the edges of the sheets and the posts, resulting in reduced annual grass cutting costs!

◆Customer Concerns◆ - The grass cutting area was on a slope, making the work dangerous. - Due to it being a school route, there were many requests from the local community, and we ended up doing grass cutting ourselves more often than we contracted out to a service provider. ◆Customer Feedback After Construction◆ - Since the site is easily visible from a distance, we considered the aesthetics and used "Chigaya Tape," made from the same material as the sheet, resulting in a beautiful finish. - We are able to effectively suppress the grass, so we would like to extend it to areas where it has not been laid in the future. - The asphalt at the edges of the sheet was rough, making it difficult to secure the sheet properly, raising concerns about it peeling up. However, we were suggested the "Macrain Sheet." After a trial installation, it has been secured without any peeling. Additionally, the gray color blends well with the pavement, which is great.

The Green Wrap Series features a smooth sheet surface that prevents the rooting of airborne seeds and reduces the accumulation of soil, dust, and dead leaves, which can lead to weed proliferation. Additionally, the high-density non-woven fabric suppresses the penetration of aggressive weeds. We offer three different specifications, so please choose according to your site conditions and budget.

Chigaya Sheet® is excellent in weather resistance and durability, demonstrating high weed control effectiveness over many years. The expected lifespan of Chigaya Sheet® is about 10 years, but with appropriate "installation methods" and "maintenance management" tailored to the site, there are cases where weed control effectiveness is maintained even after more than 10 years. We will propose solutions that take into account the weeds growing on-site, the terrain, and the surrounding environment to achieve longer-lasting and higher weed control effectiveness.

◆Customer Concerns◆ - Weeds are thriving from the edges of the block stones. Since this is a visible area in front of the station, we want to keep it clean. - During the weed growth season, we request mowing from the Silver Human Resources Center twice a month. ◆Material Selection POINT◆ - For weed prevention in joints, we usually use "joint barrier sheets (L-shaped)," but due to the uneven surface of the block stones, installation of the sheets is difficult. We selected a weed prevention rubber coat that can be applied to any shape. ◆Customer Feedback◆ - Even after four months, we are able to effectively suppress the weeds, maintaining the appearance of the area in front of the station. - The frequency of mowing during the hot season when weeds thrive has decreased, resulting in reduced management costs.

◆Customer's Concerns◆ Mowing the overgrown weeds on the slope along the town road was difficult and time-consuming. It serves as a school route for elementary students, so regular maintenance was necessary to ensure that fallen weeds did not obstruct passage. ◆Points for Sheet Selection◆ Since there were no robust weeds (such as Chigaya, Susuki, or Sugina) that could break through the weed control sheet, we prioritized ease of installation and chose the soft woven weed control sheet "Sai Shoku Ken Bi (R) Ver.2." ◆Customer Feedback◆ The weed control sheet blended well with the ground and was easy to install. It reduced the workload of mowing.

◆Customer Concerns◆ - Due to the presence of equipment and cable wiring around the cubicle facility behind the school building, weeds must be cut by hand rather than by machine. - Regular maintenance is necessary because it would be problematic if weeds are growing when the inspector comes for electrical checks. ◆Customer Feedback After Construction◆ - A sheet was raised on the concrete foundation of the cubicle, and effective edge measures were taken with attachment and Chigaya tape, so there is no worry about weeds breaking through. - Many of the workers are elderly and had difficulty with hand cutting, but the effort required for weed management has been significantly reduced. - As a measure against weeds coming through pinholes, Chigaya tape (slit type) was used, effectively suppressing weeds while also achieving a neat appearance.

Chigaya Sheet® is a highly durable weed control sheet that effectively suppresses robust weeds, with a proven track record in public works. This time, we have compiled a case study to confirm whether our company's guideline of a "10-year lifespan" for Chigaya Sheet® is appropriate, allowing everyone to verify it through actual sites. It has become a very valuable collection of case studies featuring 29 locations. Currently, the quality and performance of weed control sheets are judged based on the quality standards set by manufacturers, and in actual sites, the expected effects may not always be achieved. Through this case study collection, we hope you can understand that the "10-year lifespan" of Chigaya Sheet® is appropriate and that our method of indicating lifespan is reliable. ★We will send the case study collection to anyone who requests it. Please contact us with the request "10-Year Case Study Collection." *We have also attached a "Simplified Version - 10-Year Case Study Collection" in PDF format on the same page, featuring four selected cases. Please feel free to download and take a look.

◆Customer's Concerns - Since bamboo is growing right next to the walkway, it was necessary to regularly cut down the bamboo and remove the bamboo shoots to avoid obstructing pedestrians. ◆Customer Feedback After Construction - The hassle of removing bamboo shoots has been eliminated. - We were able to control the growth of the bamboo grass that was also thriving, which helped reduce insect occurrences and littering.

◆Customer's Concerns◆ Due to the overgrowth of weeds near the intersection, there are concerns about accidents caused by poor visibility. We want to create a beautiful landscape while controlling the weeds. ◆Points for Selecting Sheets◆ For the planting areas, we adopted the permeable and breathable Sai-Shoku Kenbi® to promote plant growth, and for the weed control areas, we used the green version of Sai-Shoku Kenbi® Ver.2 to blend in with the surrounding landscape. ◆Customer Feedback◆ The moss phlox is growing well without being overrun by weeds. The flowers are blooming beautifully and providing comfort to passersby. Even the areas without planting are effectively controlled for weeds, reducing the need for mowing.

◆Customer Issues◆ With the increase in residential areas, complaints about poor aesthetics due to weeds have arisen. Management of weeding tasks has become a burden. ◆Points for Sheet Selection◆ We selected the Sai Shoku Ken Bi (R) Ver.2, which excels in "permeability" and "air permeability" necessary for plant growth. The sheet is green in color, blending well with the landscape. ◆Customer Feedback◆ The moss phlox has grown well, creating a beautiful floral display on the slope, contributing to the town's PR. Complaints from local residents have disappeared as weeds are effectively suppressed. The management burden of weeding tasks has been reduced.

This is a collection of case studies on the installation of "weed control sheets," which are widely used as one of the measures against weeds. The challenges of weed management vary by location, such as slopes, roads, and planting areas. This document is a compilation of case studies organized by location.

The bamboo guard method is a technique that suppresses the growth of bamboo (bamboo shoots) from above. However, in some cases, there may be a desire to suppress not only the surface but also the underground bamboo roots. In such cases, we recommend installing a "subsurface root barrier" by folding a 2-meter wide bamboo guard sheet in half and setting it up in an L-shape both vertically and horizontally. The case we are introducing this time is based on a consultation we received stating, "Bamboo growing on a cliff along a public river is invading private land and causing trouble, so we want to block not only the surface but also the underground roots." We proposed the subsurface root barrier of the bamboo guard method. *Excavation will require heavy machinery.

◆Customer Concerns◆ - Around international port facilities, it is desirable to maintain clear visibility around the fence as a counter-terrorism measure, in accordance with the International Convention for the Safety of Life at Sea (SOLAS) regulations concerning the security of international port facilities. However, even after mowing, weeds quickly grow back, making it difficult to maintain visibility when weeds are overgrown, which is not favorable for the security of international port facilities. ◆Proposal Points◆ - By laying down a Chigaya sheet around the fence, visibility can be consistently improved, and long-term labor for mowing can be reduced. - To suppress weeds growing from the gaps between concrete curbs and pavement joints, the sheet was extended to the road-side pavement, and it was secured with adhesive and asphalt pins. ◆Customer Feedback After Installation◆ - The areas where the sheet was laid have maintained good visibility without the need for mowing, allowing compliance with regulations. - We would like to continue using it.

The overgrown kudzu on the slope within the park has entwined itself around the fence and invaded the roadway. This has reduced the width of the roadway, causing inconvenience to visitors coming to the park. ◆ Customer's Concerns ◆ - The kudzu has crossed over the fence and invaded the roadway, reducing its width. - Weeding the kudzu tangled in the fence has been difficult. ◆ Customer Feedback After Construction ◆ - The slope is now effectively controlled with a sheet, and there is no longer any kudzu entangling the fence, making maintenance easier. - The visibility of the fence has improved, enhancing the overall landscape. * The vine guard method includes a 10-year durable vine guard method and a 20-year high-durability vine guard method. The current site has installed the high-durability vine guard method.

In the past, with the materials and methods used, when there were significant unevenness or height differences in the pavement joints, the strong grass joint sheet would float above the pavement. Additionally, it was difficult to apply, leading to poor workability. However, by changing the materials and methods this time, it has become applicable even to joints with unevenness and height differences. Furthermore, using a roller for pressing has improved workability. Previously, both adhesive and sealing materials were used, but now it is possible to achieve adhesion and sealing with just "Adhesive D Touch." Additionally, the process of spreading the adhesive on the sheet with a notched trowel has been eliminated, resulting in a reduction of tools and less mess when applying the sheet.

◆Customer's Concerns◆ - The asphalt pavement at the edge of the sidewalk was rough, allowing weeds to grow and obstructing passage. - Weeds were also growing through the gaps in the erosion control sheet that had already been laid on the slope, invading the sidewalk and hindering passage. ◆Construction Points◆ - Since the rough areas of the asphalt were about 0.5 meters wide, we adjusted the width by cutting the Macrain® sheet with scissors to fit the site during construction. ◆Customer Feedback After Construction◆ - The weeds in the asphalt pavement have been suppressed, and the widened path has made it more comfortable for pedestrians and cyclists to pass. - Weeds were growing through the gaps in the slope, but this construction has addressed the gap issue, effectively controlling the weeds on the slope as well. - The gray color blends well with the asphalt, enhancing the overall appearance.

◆Customer Issues◆ - The edges of the asphalt sidewalk were uneven due to weeds breaking through, narrowing the passageway. - Weeds growing on the slope next to the sidewalk were invading the sidewalk through the gaps in the fence, further narrowing the path. - I wanted to cover the asphalt areas where weeds were breaking through with a weed control sheet from above, but I couldn't find a solution because regular weed control sheets deteriorate when stepped on by pedestrians. ◆Proposal/Construction Points◆ - We proposed using Chigaya Sheet® for the slope area and Maclean Sheet® for the asphalt part of the sidewalk. - By thermally welding the Maclean Sheet®, we eliminated the lifting at the edges, reducing the risk of the sheet curling and pedestrians tripping. ◆Customer Feedback After Construction◆ - By using Maclean Sheet® for the sidewalk, we were able to address the weeds breaking through the asphalt while allowing pedestrians and bicycles to pass, thus widening the path. - By combining Chigaya Sheet® instead of laying the entire area with Maclean Sheet®, we achieved cost savings.

The bamboo guard method is a technique that suppresses the growth of bamboo (bamboo shoots) from above. However, in some cases, it may be necessary to suppress not only the surface but also the underground bamboo roots. In such cases, we recommend folding a 2-meter wide bamboo guard sheet in half and installing it in an L-shape both vertically and horizontally, which we call "subsurface root prevention." In this particular case, the pathway facing the slope where bamboo is growing was not paved, creating a risk that underground bamboo rhizomes could invade and lead to the emergence of bamboo (bamboo shoots) from the pathway. By adopting the subsurface and surface installation (L-shaped installation), we have ensured the pathway's safety and reduced the risk of fallen bamboo from the slope. *Excavation will require heavy machinery.

◆Customer Concerns◆ - There were complaints about poor visibility due to overgrown weeds at the T-junction where the prefectural road and city road intersect. Additionally, the poor visibility posed a risk of accidents. ◆Sheet Selection Points◆ - We adopted McLean sheets as they are 'high durability' and less likely to 'curl up.' - Since it is near an intersection, curling of the sheet could lead to accidents, so we used 'Hurricane Net' at the edges of the sheet. - For the edges that are on concrete, we used concrete pin sets to ensure they are securely fixed, not just welded. - We used 'Weed Prevention Rubber Coat' near the utility poles to address weed issues from the edges. ◆Customer Feedback◆ - Even after one year, weeds have been effectively suppressed. - There has been no curling of the sheets due to wind, allowing for safe passage.

To fully demonstrate the effectiveness of weed prevention, it is necessary to select and install appropriate materials. 【Case 1】Weeds from the edges of concrete Simply fixing the edge of the sheet with pins will leave gaps. By firmly adhering the sheet to the concrete with "Attach," "Uretouch," or "D Touch," you can prevent weed growth. 【Case 2】Weeds from overlapping parts of the weed prevention sheet Even if the sheets overlap by more than 10 cm, weeds can still grow through slight gaps. You can prevent this by adhering with "Attach," "Uretouch," or "D Touch," and additionally using "adhesive tape." 【Case 3】Weeds from the edges of structures Around structures, the weed prevention sheet should be installed with cuts. Please use "adhesive tape" on the cut areas and "weed prevention rubber coat" at the edges of the structures. 【Case 4】Weeds from pin installation areas Please use "adhesive tape (slit type)" at the pin installation areas. When applying, it is important to press firmly; otherwise, weeds may emerge from lifted areas of the seal, so caution is necessary. 【Case 5】Weeds penetrating through Depending on the type of sheet, some weeds with strong penetrating power may break through.

◆Customer's Concerns◆ - Strong weeds like horsetail have penetrated the asphalt and sprouted, obstructing the passage of bicycles and pedestrians. (Weeds are growing from cracks in the traffic area, not just at the edge of the sidewalk.) ◆Customer Feedback After Construction◆ - With the weeds gone, bicycle traffic has become smoother. - The height difference of the joint barrier sheet is not very noticeable anymore.

◆Site Conditions◆ - The landscape was compromised due to overgrown weeds. - There were supports around the joints, making it labor-intensive when using sheet-type weed control materials. ◆Impressions After Construction◆ - The surface of the NEO sealing hardened quickly, requiring frequent leveling work. (This may vary depending on weather and site conditions.) - One month later, during the peak of weed growth, it has been effectively suppressed. This leads to a reduction in the labor required for weeding that was previously done every time weeds appeared.

◆Site Conditions◆ - Since "Chigaya Sheet" has been installed on the slope of the prefectural road, it is effectively suppressing weeds; however, weeds such as Mehisiba and Enokorogusa have emerged from the joints of the sidewalk. ◆Impressions After Construction◆ - There are few materials and tools required, making it possible for one person to carry out the work. - No special skills are needed, so anyone can easily perform the installation.

◆Site Conditions◆ - Dust has accumulated in the joints of the sidewalk curbs and cracks in the sidewalk, leading to overgrown weeds. There have been many requests for grass cutting due to it obstructing passage. - There were areas with significant pavement elevation differences or deterioration that could not be addressed with conventional joint measures. ◆Feedback on Construction (Post-Construction)◆ - Since we were able to address areas that had not been manageable before, this will help reduce the need for grass cutting work.

◆Site Conditions◆ - Dust has accumulated in the joints of the sidewalk curbs and cracks in the sidewalk, leading to overgrown weeds. There have been many requests for grass cutting due to obstruction of passage. - There were areas with significant pavement elevation differences or pavement deterioration that could not be addressed with conventional joint measures. ◆Feedback on Construction (Post-Construction)◆ - Since we were able to address areas that had not been manageable before, this will lead to a reduction in grass cutting work.

Please include "Weed Control Sheet Case Collection (outside of Road Department) request" in your inquiry.

◆Customer's Concerns◆ Weeds on the water purification plant premises were invading the adjacent residential properties, leading to complaints from residents. Additionally, due to the complex layout of the buildings, it took a long time to mow the grass, and within 2 to 3 months after mowing, the weeds would quickly grow back. ◆Feedback After Construction◆ We were able to reduce the time spent on mowing the grass. We also ensured that weeds would not emerge from the gaps in the concrete by applying strong adhesive, which gives us peace of mind. *We have a collection of case studies that verifies 29 locations across the country where Chigaya sheets have been used for over 10 years. Some of these locations have been in use for over 20 years. We would like to offer this valuable collection of case studies for free.
