Vegetation substrate injection work - Green Green Mat method

A groundbreaking new method for creating a stable vegetation foundation layer on slopes.

The vegetation substrate injection method, Green Green Mat Method, is a new technique for greening slopes that addresses the challenges of greening non-soil areas such as sandy soils and bedrock. It solves issues such as the loss of vegetation substrate due to rainfall and spring water, as well as the sliding of vegetation substrate on steep slopes and in areas with severe freeze-thaw cycles, enabling stable retention of the vegetation substrate. NETIS Registration Number: CG-170003-A 【Features of the Vegetation Substrate Injection Method - Green Green Mat Method】 1. Applicable even in harsh natural environments. 2. The vegetation substrate does not wash away. 3. The mixture of herbaceous seeds can be reduced. 4. The mat structure allows for easy emergence of woody plant cotyledons. 5. Maintenance is generally unnecessary. 6. Effective as a measure against animal damage. For more details, please contact us or download the catalog to view.

Surface Treatment Worker Multi-Protection Method

Surface treatment works that can be expected to prevent erosion, prevent the generation of polluted water, prevent sand drift, and prevent plant invasion.

The Multi-Protection Method is a surface treatment technique that involves spraying multiple (multi) biodegradable fibers with different decomposition rates onto the ground surface, which can help prevent erosion, reduce the generation of polluted water, prevent sand drift, and inhibit the invasion of plants from surrounding areas. **Features of the Multi-Protection Method:** 1. The surface is covered, enhancing erosion resistance and promoting plant growth through mulching effects. 2. By utilizing multiple (multi) organic fibers with different decomposition rates, it protects the foundation over the long term. 3. The spraying work uses mechanical construction, allowing for the avoidance of slope work, making it safer. 4. Construction can be carried out using various methods, including manual labor, hydroseeders, and helicopter slurry spraying. For more details, please contact us or download and view the catalog.

Rainwater erosion prevention, seed loss prevention, sand drift prevention - Polysoil method

By applying the non-ionic polymer soil granulation agent and erosion control agent Polisoil, it demonstrates effectiveness in preventing rainwater erosion, seed loss, and sand drift!

NETIS Number: KT-210082-A The Polisoil method is a spraying and greening technique that demonstrates rainwater erosion prevention, seed loss prevention, and sand drift prevention effects by applying Polisoil, a soil granulation agent and erosion control agent made from non-ionic polymers. The Polisoil method includes Polisoil greening, which mixes with seeds, fertilizers, fibers, etc., and Polisoil spraying, which serves as an erosion control and dust prevention measure. This method has a track record of approximately 650 hectares within Okinawa Prefecture, equivalent to about 250 times the area of Okinawa Cellular Stadium Naha (0.026 km²), and can be widely utilized in various applications such as road slopes, riverbanks, mountain slopes for erosion control, large-scale construction projects, solar power plant construction, and agricultural land. **Features of the Polisoil Method** 1. Environmentally friendly. A synthetic resin secretion that does not contain plasticizers unique to vinyl acetate, making it environmentally friendly. 2. Good workability. Excellent water resistance and quick drying provide outstanding workability. 3. All-round. It can widely accommodate soil-related applications such as greening promotion, soil improvement, and erosion prevention. 4. Optimal for greening methods. 5. Protects the soil surface. 6. Good constructability and cost-effectiveness.

Cost reduction type spraying method frame R.T. frame method

Anyone can easily and quickly install it! Prevents mortar peeling and reduces material loss.

The "Cost Reduction Type Sprayed Frame Construction RT Frame Method" is a simple frame construction method that involves spraying onto a sloped surface. The sprayed mortar naturally expands in the shape of the RT frame, allowing anyone to easily and quickly carry out the construction. An auxiliary mesh for the RT frame is installed under the beams to prevent mortar from falling off and to minimize material loss. 【Features】 - Not association-controlled, so anyone can easily and quickly perform the construction. - Spraying onto a sloped surface results in minimal material loss. - Four types of frames can be chosen based on site conditions. - More cost-effective than conventional methods. - Beams use auxiliary mesh to prevent mortar from falling off (Type IV also uses auxiliary mesh for vertical beams). *For more details, please refer to the PDF materials or feel free to contact us.

As a countermeasure against frequent short-duration heavy rain, Easy Shelf Method for embankment use.

The Easy Shelf Method for simple spraying can be utilized as a countermeasure against the frequent short-duration heavy rains occurring recently!

The Easy Shelf Method, promoted by the National Slope Disaster Prevention Association, which is managed by K.F. Corporation, can be utilized as a countermeasure against the recent frequent short-duration heavy rains! 【Countermeasure Situations】 1. As a countermeasure against erosion and collapse of slopes due to surface water: Easy Shelf Method + Vegetation within the frame 2. As a countermeasure against sliding collapse due to infiltrating water: Easy Shelf Method + Mortar spraying within the frame 【Comparison with Precast Grid Frames】 1. All beams are continuous, increasing resistance to ground collapse. 2. Surface water can be smoothly drained. 3. It is closely attached to the ground, making it less susceptible to erosion. 4. It is expected to have a suppressive effect on surface collapse.

Slope construction method: Cost-reduction type spraying method framework, R.T. frame method.

A spray method frame that can be constructed anywhere in the country, designed for cost reduction! It maintains the strength of conventional spray method frames and simple spray method frames while improving workability and reducing costs.

NETIS Registration Number CG-100009-A. 【Advantages of Using the RT Frame Method】 1. Minimal spraying loss and easy construction. Instead of finishing in a dome shape like conventional simple formwork, it is finished in a triangular shape. The sprayed mortar naturally forms into a triangular shape, resulting in minimal material loss and allowing anyone to easily carry out the construction. 2. Faster drafting and performance measurement due to the management of the RT Frame Method's development drawings. 3. Significant cost reduction when used in conjunction with rebar insertion work! It can be used in combination with rebar insertion work. This combination serves as a restraint for slopes, allowing for a significant reduction in costs compared to conventional methods. 4. Adjustable frame span and rebar quantity according to site needs! The RT Frame Method offers five standard types, but it can be adjusted for frame span and rebar quantity based on site needs, pursuing both safety and cost efficiency. *For stability calculations and estimates, please consult our company.
