Drainage board has the function of smooth drainage, waterproof, root barrier, heat insulation, high pressure resistance, breathable, mainly used in highway, railway roadbed, embankment, slope protection layer, garage roof greening, roof garden, football field, golf course, bath project, subway tunnel and other projects, easy to construct and remove.

Drainage board construction

1. When inserting the board, after the insertion machine is in position, the casing is driven by vibrating hammer to sink against the jack position, the drainage board passes through the casing and is connected to the anchor shoe at the end, the casing tops the anchor shoe to insert the drainage board to the designed depth of entry, after pulling up the casing, the anchor shoe remains in the soil together with the drainage board, and then the continuous drainage board is cut, that is, a drainage hole insertion operation is completed.Then cut off the exposed head and fill it in, and the construction of the insert is completed.

Drainage board price

Drainage board from the use, specifications, thickness, style and so on the reverse side of a wide variety, which causes the price difference is relatively large, generally we commonly offer a good bit in about 25-35 yuan, the quality of ordinary point price in about 6-8 yuan, for reference.

Drainage board role

Anti-drainage protection board have the concave and convex hollow standing rib structure, can quickly and effectively export rainwater, greatly reduce or even eliminate the hydrostatic pressure of the waterproof layer, through this active water guide principle can achieve the effect of active waterproofing.Anti-drainage protection board can effectively protect the structure and waterproof layer, and resist all kinds of acid and alkali in the soil and the root thorn of plants.It protects the building and the waterproofing layer from damage when backfilling the external walls of the basement.The drainage board also has sound insulation and ventilation and moisture control functions. Laboratory data shows that polyethylene (HDPE) anti-drainage protection board can effectively reduce indoor noise by 14 decibels at 500 HZ, which has obvious noise reduction and sound insulation functions.Waterproof water guide plate in the ground or wall use, also play a very good ventilation and moisture-proof function.
