PE Self-adhesive Waterproofing Drainage Board

PE Self-adhesive Waterproofing Drainage Board

Description

CANLON PE self-adhesive waterproof and drainage board is a polymer waterproof board with drainage function. It is mainly composed of concave and convex waterproof and drainage board and adhesive tape. The adhesive tape can facilitate the installation and fixation of the material. It is mainly used for waterproofing and drainage of underground tunnels. It has the characteristics of good drainage effect, excellent waterproof performance and easy installation.

Specification

Product Features

• High tear and puncture resistance.
• Resistant to mildew and corrosion by acids, alkali, salts and other media in the use environment.
• Heat and low temperature resistance, high adaptability to the construction environment.
• Easy Installation. With "Velcro" adhesive tape, it can be directly bonded to the non-woven buffer layer (self-adhesive cloth) , no hidden danger of nailing and perforation , the construction efficiency is higher.
• Perform both waterproof and drainage functions, and the waterproof effect is more significant.

System Advantages

The tunnel construction destroyed the original water system balance of the mountain, and the tunnel became a channel for the accumulation of groundwater near the mountain it passed through. When a tunnel is connected to a water-bearing stratum and the waterproofing and drainage facilities and methods of the lining are imperfect, tunnel water damage will inevitably occur. Water leakage in tunnels is very harmful, difficult to rectify, and costly. Therefore, it is very important to do a good job in tunnel waterproofing and drainage. Tunnel waterproofing and drainage can "nip problems in the bud" and get twice the result with half the effort.

Mountain water system balance

Tunnel leakage

The special PE self-adhesive waterproof and drainage board for tunnels is directly bonded to the buffer layer(self-adhesive cloth) through its own adhesive tape, eliminating the need for ordinary plate welding and the hidden danger of nailing and perforation. The construction speed is fast, saving labor, time and cost.

The self-adhesive tape is directly bonded to the buffer layer (self-adhesive cloth) without the hidden danger of nailing or perforation.
