Green Sanjiang Plastic protective drainage board itself uses a high-density polyethylene (HDPE) sheet, the material itself is waterproof polymer materials, and its characteristic structure itself can play a drainage layer of flexible waterproof protection and puncture-resistant roots and other complex functions, as opposed to the traditional drainage system that has the following disadvantages: 1, drain construction period is short: drainage water protection board empty shop directly on the waterproof layer, unlike the rigid protection needs conservation, backfill can then follow up greatly shorten the construction period. 2, low cost drain: drainage water protection board has a transparent structure system, drainage ability drainage board manufacturers, wholesale, you can cancel the garage roof to find the slope layer, using water gravity drainage, and can replace the original two-way reinforcement protective layer of fine aggregate concrete drainage board manufacturers product images, instead of the original gravel drainage layer, simple construction drainage board manufacturers, low construction costs, which would greatly reduce the project cost. 3, drainage board form a waterproof layer protection: Green rivers drainage water protection board laid directly on the waterproof layer, providing a flexible protective waterproof layer, unlike the rigid protective layer construction is likely to damage the waterproof layer, but also the isolation layer Shandong drainage board manufacturers, and the flexible protective layer is more likely to edge parts of the complex structure protection, can form a complete protection system. 4, anti-root puncture drainage board has the ability to: Green Sanjiang plastic protective drain line from repression by the HDPE geomembrane, plant roots can effectively resist puncture, without a separate set up anti-root puncture.
