Traditional weed control methods have the following issues: Weed control sheets: - Replacement is necessary within a short period due to UV degradation. - Installation is easy, but the lifespan is short. - There are concerns about peeling and scattering due to strong winds. In the case of concrete paving (seal concrete): - Difficult to install in narrow sites due to heavy machinery. - The processes of formwork installation and surface finishing are complicated, requiring skilled workers for formwork. - The curing period is long. - Joint materials must be installed to prevent cracking. In the case of mortar spraying: - Difficult to install in narrow sites due to heavy machinery. - It is necessary to use wire mesh to prevent cracking and peeling. - Quality is affected by mix design and weather conditions. - There is variability in quality after curing, with concerns about cracking due to drying shrinkage. 《High durability and high-functioning weed control materials solve traditional problems!》 Concrete canvas: A concrete mat that hardens just by adding water. Grasstop: Prevents weed growth for a long time, making management easier. Denka Fuse Grass: Hardens in 5 minutes with water, allowing for opening the next day with rapid hardening material. *We also handle various other weed control materials.
