Advantages and construction technology of pvc drainage plate coil

PVC drainage board is extruded from high-density PVC material, which makes full use of the characteristics of high density, high strength and amorphous structure of PVC material to make a cross drainage board. This is a patented design with a cross support column and a top column in the middle. Using the large plane of the supporting column and the arrangement of the middle top column, it is ensured that the geotextile will not sink after covering the soil, leaving enough drainage space. Pvc drainage board has many advantages. The following is a brief introduction to pvc drainage board.

Advantages of PVC drainage plate coil

1, auxiliary waterproof function After the drainage coiled material is laid, a new waterproof layer is formed due to hot welding, which has both drainage function and secondary waterproof function.

2. The common waterproof coiled material with root limit function has no root limit function, while PVC coiled material has strong root limit function because of its high density. The thickness of the film can be adjusted according to the requirements of root spacing to achieve the effect of root spacing.

3. Not only can it be bonded, but it can also be thermally bonded. Because PVC material is amorphous, the use of special glue can effectively destroy the surface structure of the material, so that the two films can be effectively fused together, playing the role of waterproof and root separation. It can also take the form of mechanical ironing.

4. The compressive strength of high-strength PVC coiled material is high, which is 1.5 times that of PS coiled material with the same thickness and 2.5 times that of HDPE.

5. Anti-collapse design All drainage coils adopt anti-collapse design. Due to the adoption of the middle supporting top column structure, the geotextile will not sink after covering the soil, thus ensuring sufficient drainage space.

Construction technology of pvc drainage board

1, the construction wall surface shall be solid, smooth and free from sand, spikes, hollows and potholes.

2. Apply adhesive on the building wall to bond the drainage board.

3. Fix the drain plate with rivets.

4. Evenly spray interface emulsion on the surface of the drainage board.

5. Paint cement mortar on the drainage board and embed the grid cloth.

6. Powder the second layer of cement mortar to cover the grid cloth and smooth it with mortar.
