The base plate of hxhp composite drainage network is made of high impact and high compression polystyrene (HIPS), which can resist long-term high pressure without deformation. This long-term compression resistance can not only withstand the weight and load of concrete floor, but also withstand the inevitable external pressure and impact force during construction, such as vehicles, workers' trampling, concrete pouring and so on, The purpose of the filter geotextile on the bottom plate is to ensure that the drainage channel will not be blocked by foreign materials, such as adding soil particles or concrete

Typical applications:

Hxhp composite drainage network is superior to traditional stone ceramsite drainage and other filters in terms of drainage function and economic benefits. It is widely used in retaining wall, basement, tunnel, slope protection and highway subgrade

Composite waterproof and drainage board (also known as composite waterproof board, composite drainage board, three-dimensional geotechnical drainage board, three-dimensional composite waterproof and drainage board, tunnel drainage board) is a new type of waterproof and drainage material which integrates drainage and waterproof functions, and has high void ratio and high compressive strength. The three-dimensional geonet core is composed of filter geotextile on one side and two-step and one membrane on the other side, which has the function of "filtration drainage air permeability water separation protection".

Application: mainly used for drainage of highway, tunnel, subway, port, landfill, roof garden, sports ground, etc.
