Flat waterproof drain pipe board/plastic drainage sheet

The new type heat melting integrated plastic drainage board is superior to other types of drainage board which is widely used at present in aspects of integrality, durability, tensile strength, and capacity of water discharge.

The new type heat melting integrated plastic drainage board consisted of filter and wick board, as showing in the below picture, the filter and wick board are clung together by heat melting, that make the it has the advantages in integrality, saving the filter material, capacity of water discharge.

Main applications:
The drainage of highway subgrade and railway subgrade mainly solves the drainage of surface water, groundwater and road surface water. The advantages are:
1.Strong drainage capacity. It’s similar to a free-drainage foundation.
2.High compression capacity and stiffness, able to withstand traffic load.
3.Large porosity, able to block the rise of capillary water.
4.High tensile strength and anti-tensile modulus.Expect for drainage and isolation, it also has the better effect of foundation reinforcement.
5.Easy installation.

Large-scale drainage projects need to be built on sea reclamation , or on soft foundations. So the soft foundation treatment has become the key point. And the usage of heat melting integral drainage board can replace sand layer as drainage layer, and solve the problem sand filler shortage in some areas.
