KM-style drain mat "KMD type"

Easily attachable to the drainage pipe! Strong in compressive and impact resistance, with no significant decrease in drainage performance.

The "KMD type" is a drainage mat that can be easily attached to drainage pipes in waterways, retaining walls, etc. with a one-touch mechanism. By inserting and installing this product into the backfill area of weep holes provided in drainage ditches, it prevents the outflow of soil and sediment from the backfill area while simultaneously increasing the catchment area, allowing for smooth water discharge. It is a large filter with a greater catchment area compared to the KMK type catchment filter (basket type). It can also be used as a material to prevent suction in drainage pipes of road retaining walls. It is lightweight, making transportation and installation easy. We will prepare connection pins according to the pipe diameter, so please let us know the diameter (from 40mm to 150mm). 【Features】 - The inner core material has a filament structure, allowing for larger gaps. - The use of non-woven fabric filters enhances drainage and collection efficiency by increasing permeability. - It is strong against compression and impact. - There is no significant decrease in drainage performance. - Its lightweight design makes transportation and installation easy. - It can be easily attached to drainage pipes. *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Installation Method】 1. Insert until the pin stops into the drainage pipe on the backfill side. 2. If the retaining wall has a slope, insert it in the same manner as a vertical wall. The pin can be installed by bending it. 3. When using backfill soil with a high content of clay, use in conjunction with a sand and gravel filter layer, etc. *For more details, please refer to the PDF document or feel free to contact us.
