Build drainage board / drainage board is made of high-density material, extrusion, takes full advantage of PVC material density, high strength, the material properties of amorphous structure made of cross drainage board. It is the use of cross support column and top post intermediate additional patented design, the use of large flat top and middle column are arranged in the form of support columns, to ensure complete soil cover does not sag after geotextiles, leaving enough space for smooth drainage. At the same time the size of eight cross support pillar reinforcement, which greatly increases its compressive strength. The product is a fixed width, length can be customized according to the needs, to facilitate the construction paved 25mm build drainage board prices, after the formation of auxiliary set to complete a new waterproof layer and every root layer. Drainage board products fixed width, length can be customized according to the needs, to facilitate the construction and auxiliary set, after the formation of auxiliary set to complete a new waterproof layer and every root layer. Drainage board is made of high-density polyethylene material, extrusion, takes full advantage of PVC material density, high strength, the material properties of amorphous structure made of cross drainage board. Drainage board is the use of an additional cross support column and top post in the middle of the patented design factory direct 25mm build drainage board, the use of large flat top and middle column are arranged in the form of support columns, to ensure complete soil cover does not sag after geotextiles, leaving enough open space for drainage . Meanwhile drainage board cross support columns have size eight reinforcement, greatly increasing its compressive strength. Drainage Board drainage: expanded particles uniformly distributed between 30% continuous pores, clogging. www. Drainage Board .net can maintain a stable permeability. Drainage board insulation: Because the foam itself has numerous independent bubbles, has a high quality insulation using 25mm build drainage board to cushion the external heat source.
