Drainage Sheet

Capillary Drainage Sheet

PVC groove drainage sheet was Using PVC high-density polymer material, with good toughness, buried in the soil can play the role of knotting soil. Use of dense groove, when buried let the groove face down,so that the water from the bottom to the up was sucked into the dense made of plastic core and outer filtering cloth. In the state of hot melting, it is formed into three-D network structure. It has two shapes: rectangle and round. This kind of pipe has some advantages: good drainage, high pressure resistance, light weight, so it is very popular in some projects...Chat Now

PVC capillary dense groove drainage board be made by PVC high density polymeric material. It is better toughness and be placed inside the soil and the building structure. The water be sucked back into capillary slot by gravity or capillary force and fill it. The product be shape close by Water surface tension. The difference of level will come into being siphon force. Gravity, capillary force and siphon force wille be combine to collect, transport and drain the water.


Product features
1. No blockage: direct use of the natural gravity phenomenon to produce the separation effect of soil and water;
2. High permeability: 20% hole opening rate and large effective water absorption area;
3. High drainage efficiency: high efficiency of capillary force, force and drainage;
4. Strong resistance to soil pressure: arch bridge structure design, effective dispersion of stress distribution;
5. No-use grading: with self-cleaning function, without grading filter layer, it can directly cover the soil for backfilling;
6. Simple construction: drum packaging does not take up the volume, reducing transportation, storage,

management and work costs, and does not need joints to improve efficiency;
7. Flexural flexibility: it can be closely combined with the terrain to form an infinitely long, non-flat highway;
8. Good durability: PVC high density polymer material is adopted to resist ultraviolet rays and to have good durability.



Underground drainage of golf course, slope drainage, underground irrigation in arid areas, underground drainage of park green area, underground drainage of low wetland agriculture, drainage of retaining wall and tunnel engineering, underground drainage of sports field, drainage of railway and road subgrade,water supply and drainage of horticultural landscape

Construction technology

1. In principle, the hole groove (suction surface) is generally downwards,

which causes the soil particles to fall due to gravity and prevent blockage.

2. The point end hole of the capillary permeable drainage zone shall be sealed with

silica gel to prevent the particles from entering.

3. The slope buried in the capillary drainage zone is recommended to be

at least 2% (to generate siphon).

4. The bottom of the buried ditch shall be leveled and compacted, and then this

capillary drainage belt shall be laid.

5. Under the condition of mud, it is not suitable to be buried in the construction,

and the constructionshall be carried out after the improvement of the muddy condition
