New feature penetration trench! It is easy to construct and has a narrow excavation width, making it highly economical.
The "D-product" does not require a single-sized crushed stone layer because the permeable concrete part functions as a permeable layer. In addition to permeability, it also has a water retention function due to the permeable concrete. Furthermore, by installing a steel filter to prevent clogging at the pipe opening, maintenance such as debris removal is possible. 【Features】 ■ No single-sized crushed stone layer is needed as the permeable concrete part functions as a permeable layer. ■ It allows rainwater to directly permeate into the soil, eliminating the need for a permeable sheet. ■ Easy to install and has a narrow excavation width, making it cost-effective. ■ In addition to permeability, it also has a water retention function due to the permeable concrete. ■ When combined with a permeable well, it enables safer drainage treatment. *For more details, please refer to the PDF document or feel free to contact us.
