　　PVC capillary waterproof and drainage board:

　　Our company's PVC capillary drainage board equipment can produce PVC capillary drainage boards with different widths such as 1 meter, 2 meters, and 3 meters. Our company produces PVC capillary waterproof and drainage boards with complete specifications, low prices, and quality that meets the TB3354-2014 standard. Welcome to inquire by phone.

　　The PVC capillary drainage board is made of high-density PVC polymer material, which has good toughness and can be buried in the soil to play a role in binding the soil; And instead of the traditional design, it adopts a dense groove with a large inside and small outside, and when buried, the groove faces downwards, allowing the water flow to be sucked into the capillary conduit from bottom to top; In this way, soil particles will naturally settle due to gravity and will not enter the capillary conduit with the water flow, nor will they cause sedimentation near the inlet groove; However, the internal groove can not only allow water to enter, but also cause the consequence of water leakage. At this time, the capillary waterproof drainage plate uses surface tension to seal the water on the groove and prevent it from leaking back; When water enters, capillary action naturally affects the moisture in the soil until it is filled and discharged outward by gravity; When the water flow reaches the outlet, it will create a siphon effect due to the drop, further affecting the interior of the soil and greatly increasing the suction and drainage effect.

　　Product Features

　　1. Non clogging: Directly utilizing the natural gravity phenomenon to produce soil water separation effect;

　　2. High permeability: With an opening rate of up to 20%, it has a large effective water absorption area;

　　3. High drainage efficiency: utilizing capillary force, force, and high drainage efficiency;

　　4. Strong resistance to soil pressure: The arch bridge structure design effectively disperses stress distribution;

　　5. No grading required: With self-cleaning function, no grading filter layer is needed, and can be directly backfilled with soil;

　　6. Easy construction: Roll type packaging does not take up volume, reducing transportation, storage, management, and work costs, and does not require joints to improve efficiency;

　　7. Flexible and flexible: It can closely fit with the terrain, forming an infinitely long and unbreakable highway;

　　8. Excellent durability: Made of high-density PVC polymer material, it is UV resistant and has good durability.

　　【 Application scope 】 Underground drainage for golf courses, hillside drainage, underground irrigation in arid areas, underground drainage for parks and green spaces, drainage for low wetland agriculture, drainage for retaining walls and tunnel engineering, underground drainage for sports fields, drainage for railway and highway roadbeds, underground drainage during rainy seasons, and water supply and drainage for parks and scenic spots.

　　【 Basic Construction Specification 】 1. The hole groove (suction surface) should generally face downwards to allow soil particles to settle due to gravity and prevent blockage.

　　2. The high point holes of the capillary drainage belt must be sealed with silicone gel to prevent particles from entering.

　　3. The slope of the capillary drainage belt should be at least 2% (to generate siphon force).

　　4. The bottom of the buried ditch must be leveled and compacted before laying this capillary drainage belt.

　　5. In mud conditions, it is not suitable for construction and burial. Construction should only be carried out after the mud conditions have improved.
