The traditional use of brick tile drainage as a guide filter layer, the use of more pebbles or gravel as a drainage layer, the water discharged to the designated place. Now replace the pebbles treatment layer with a drain to drain it saves time, effort and energy, waterproof blanket saving investment, but also reduce the load of the building waterproofing and drainage board has a hollow stud bump structure can effectively export the clapper rain, greatly reduce or even eliminate the hydrostatic pressure waterproof layer, through this initiative to guide the water can reach the active principle waterproof effect.
