In recent years, while measures against weeds have become an important issue for maintaining landscapes and ensuring traffic safety, there is a growing demand for more efficient maintenance management amid labor shortages and limited budgets. One of the widely used methods to address these challenges is "weed control sheets." However, there are also many voices expressing dissatisfaction, such as "weeds have penetrated through the sheet" and "it deteriorated quickly," indicating that the expected effects were not achieved. Even though it is referred to as "weed control sheets," the materials and structures vary by product, and the applicable locations and types of weeds that can be suppressed also differ. Therefore, choosing the right sheet is essential to achieve long-term weed control effectiveness. By introducing appropriate weed control sheets, it is possible to prevent the deterioration of landscapes and the decline of safety due to rampant weeds, as well as lead to long-term reductions in labor costs and maintenance expenses associated with weeding operations. This time, we have summarized the key points to consider when selecting weed control sheets in an easy-to-understand manner. Please download it and make use of it.

In the maintenance and management of public facilities and roads, weed control sheets are widely used as an effective means of preventing weeds. However, there are not a few cases where grass has grown despite the installation of weed control sheets months or years later. The factors for failure vary by site, but one possible factor is inadequate edge treatment. - The edge between the weed control sheet and structures like concrete - The overlap between weed control sheets - The edge between the weed control sheet and guardrail posts Simply securing the weed control sheet with pins inevitably creates gaps at these edges. Weeds can grow through these small gaps, eventually pushing up the weed control sheet, and in severe cases, even lifting it up. To prevent this, edge treatment becomes crucial. To maintain the effectiveness of weed control sheets over a long period, design and construction management that includes edge treatment is essential. Incorporating edge treatment into the specifications from the design phase and thoroughly managing construction on-site directly contributes to reducing long-term maintenance costs.

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.
