Drainage board in the construction of the specification you noticed?

Drainage board sub-coiled material and sheet two series of which the coil is divided into 'hot melt' and 'lap joint' and 'self-adhesive' three types, using a special process to press the plastic sheet out of the closed convex cylindrical shell Body, forming a concave-convex film, shell continuous, with three-dimensional space and a certain support height, thermal adhesive butyl rubber strips at the time of edge processing production, geotextile filter layer covering the top of the shell, used for seepage, hydrophobic, drainage and water storage products . Also known as: self-adhesive PE drainage board, row sparse board, drainage protection board, water filter board, plastic bump drainage board, plastic sandwich board.

1. Store the drain board in a dry, ventilated environment to prevent exposure and keep away from fire.

4. The single-spread geotextile shall be lapped with 150cm. The lap joint shall be sealed with glue or sand to avoid movement, and then backfilled. The first layer of backfill soil shall be ensured after compaction, and the layered backfill must be compacted.
