Water storage and drainage board is a newly developed geosynthetic material, which is mainly used in roof drainage, roof greening and roof gardens. It is mainly made of polystyrene (HIPS) or polyethylene (HDPE). There are many merchants selling this kind of water storage and drainage board on the market at present, but most of them are dealers, but there are not many manufacturers of high-quality and low-cost drainage boards.

the price of water storage and drainage boards ranges from a few to a dozen, which cannot be clearly expressed in one sentence. It should be determined according to the material, specifications and quantity. How to choose a good quality water storage and drainage board manufacturer also has a knack:

1. "Looking" means observing the color of the following purchased drainage boards from the surface. The plastic drainage boards produced by new materials have delicate appearance and patterns, and the good quality drainage boards shine. The drainage board made of recycled waste has dark brightness, unsmooth surface and impure material.

2. "Lifting" means feeling the weight by hand. Poor quality water storage and drainage boards are often lighter than good quality water storage and drainage boards, while good quality water storage and drainage boards are more solid and stable in texture.

3. "Folding" means that when buying a drain board, you can bend the drain board properly. If it is easy to break, the drain board will be inferior, otherwise the quality of this kind of drain board will be slightly better.

4. "Pressing" means squeezing the drain board to be purchased with proper force. The drain board made from recycled waste is brittle and weak. Drainage boards made by drainage board manufacturers have good toughness and moderate hardness, so if the drainage boards you choose are soft and brittle, they are mostly inferior quality drainage boards.

I hope I can help you, thank you, and hope to adopt it.
