Storage and drainage board-蓄排水板

Storage and drainage board

Construction of drainage board：

The plastic base plate of the conical protrusion (or hollow cylindrical porous) is made of high-density polyethylene (HDPE). The top surface of the conical protrusion (or hollow cylindrical porous) is bonded with a filter layer of geotextile to prevent the passage of soil particles, thereby avoiding channel blockage and ensuring smooth drainage of the pore.

Advantages of drainage boards：

The traditional drainage method uses bricks and tiles as the filter layer, and more pebbles or crushed stones as the filter layer to discharge water to the designated location. Nowadays, replacing the pebble filter layer with a drainage board for drainage is time-saving, labor-saving, energy-saving, investment saving, and reduces the load on buildings.

Function of drainage board：

A good drainage system plays an important role in the construction cycle of civil engineering and the normal use and lifespan of structures. The drainage board of the HW drainage board and the porous seepage pipe form an effective drainage system, and the cylindrical porous drainage board and geotextile also form a drainage system, forming a system with seepage, water storage, and drainage functions.

Application of drainage boards：

Landscape engineering: garage roof greening, roof garden, football field, golf course, and bathhouse engineering

Municipal engineering: road subgrade, subway tunnel

Construction engineering: upper or lower layers of building foundations, indoor and outdoor walls in the basement, roof anti-seepage and insulation layers, etc

Transportation engineering: highway, railway subgrade, embankment, and slope protection layer
