dimple hdpe drainage sheet

The plastic drainage board is made of high-density polyethylene (HDPE) as the raw material base plate and is punched into a conical projection or a stiffening rib (or hollow cylindrical porous). The top surface of the conical platform is glued with a layer of filter geotextile to prevent the passage of dirt particles, so as to avoid the drainage channel obstructing and smoothing the drainage of the channel. The traditional drainage method uses brick and stone tiles as a filter layer, uses more pebbles or gravel as a drainage layer, and discharges water to a designated location. The use of drainage boards instead of cobblestone drainage to drain water saves time, effort and energy, saves investment, and reduces building loads.

The concavo-convex hollow vertical bar structure of the drainage plate can quickly and effectively export rain water and greatly reduce or even eliminate the static water pressure of the waterproof layer. Through this active water guiding principle, the active waterproof effect can be achieved.

the material itself of HDPE drainage protection board is a good waterproof material.By using a reliable connection, the waterproof and draining board becomes a good auxiliary waterproof material.

Drainage board  can effectively protect structures and waterproofing, and resist various acid-base in soil and root thorns of plants.When backfilling the basement wall, it can protect the building and waterproof layer from damage.

Laboratory data show that HDPE drainage plate can effectively reduce 14 db and 500HZ noise in the room, and has obvious noise reduction and sound insulation function.Drain board is used in the ground or metope, also can have very good ventilated moistureproof effect.
