20mm Dimple Drain Sheet Roof Garden Retaining Wall HDPE Composite Drainage Board for Building and Construction
Product Description
The plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) as raw materials. The plastic bottom plate is punched into conical projections or stiffener convex points (or hollow cylindrical porous). It has undergone continuous innovation and research and development. The raw material has been greatly improved and changed. The compressive strength and overall flatness have been greatly improved. The width is 1 to 3 meters, and the length is 4 to 10 meters or more. .

Basic Info
The top surface of the conical projection platform is glued with a layer of filter geotextile to prevent the passage of soil particles, thereby avoiding the blockage of the drainage channel and making the channel drainage smooth. The traditional drainage method uses masonry tiles as a filter layer, and uses more pebbles or gravel as a filter layer, and drains the water to a designated location. The use of drainage boards to replace the cobblestone filter layer to drain water saves time, effort and energy, saves investment, and can also reduce the load on the building.
A good drainage system plays an important role in the construction period of civil works and the normal use and life of structures. The drainage plate and the porous pipe form an effective drainage system, and the cylindrical hollow drainage plate and geotextile also form a drainage system, thus forming a system with water seepage, water storage and drainage functions.
Our Advantages
We can do custom production and package for you.
Water diversion and drainage
The concave-convex hollow vertical rib structure of the anti-drainage protection board can quickly and effectively drain rainwater, greatly reducing or even eliminating the hydrostatic pressure of the waterproof layer. Through this active water guiding principle, the effect of active waterproofing can be achieved.
Waterproof performance: Polyethylene (HDPE) polystyrene (PVC) waterproof and drainage protection board material itself is a good waterproof material. By adopting a reliable connection method, the waterproof and drainage board becomes a good auxiliary waterproof material.
Protection
The anti-drainage protection board can effectively protect the structure and the waterproof layer, and resist all kinds of acid and alkali in the soil and the root thorns of plants. When backfilling the basement wall, it can protect the building and the waterproof layer from damage.
Sound insulation and ventilation and moisture-proof function:
Laboratory data show that polyethylene (HDPE) polyvinyl chloride (PVC) water-proof and drainage protection board can effectively reduce indoor noise of 14 decibels, 500HZ, and has obvious noise reduction and sound insulation functions. When the waterproof guide plate is used on the ground or wall, it can also play a good role in ventilation and moisture prevention.
