capillary waterproof & drain board

The product uses PVC high-density polymer material, which has good toughness and can play a role in tying the soil when buried in the soil; Adopting a dense groove design with a large inner and small outer surface, and when buried, the groove faces downwards, allowing water flow to be sucked back into the capillary conduit from bottom to top; In this way, soil particles naturally settle due to gravity, preventing them from entering the capillary conduit with the water flow, and at the same time, there will be no sedimentation phenomenon near the inlet channel; However, the internal grooves can not only allow water to enter, but also cause leakage. The capillary drainage board uses surface tension to create a sealing effect on the grooves and prevent leakage; When water enters, the capillary phenomenon naturally produces a suction effect on the water in the soil, until it is filled and discharged outward by gravity flow; When the water flow reaches the outlet, it will generate a siphon effect due to the drop, further creating negative pressure inside the soil, greatly increasing the suction and drainage effect.

Product Details

Features:
1. No blockage: Directly utilize natural gravity to produce soil water separation effect;
2. High permeability properties: with a porosity of up to 20% and a large effective water absorption area;
3. High drainage efficiency: Utilizing capillary force, siphon force, and high drainage efficiency;
4. Strong resistance to soil pressure: Arch bridge structure design effectively disperses stress distribution;
5. No use of grading; It has a self-cleaning function and does not require a graded filter layer. It can be directly backfilled with soil;
6. Easy construction: The roll type packaging does not take up any volume, reducing transportation, storage, management, and work costs, and does not require joints to improve efficiency;
7. Flexible and flexible: It can closely adhere to the terrain, forming an infinitely long, non flattened water flow expressway;
8. Excellent durability; Using PVC high-density polymer material, it is resistant to tightening the outer thread and has good durability.
