Product Description

Product Introduction
Pre-laid is one-sided self-adhesive, and wet-laid is double-sided self-adhesive. The main raw material of wet-laid waterproofing membrane is active substances, and at the same time, appropriate amount of auxiliary materials, anti-aging agents, accelerators and other additives are added. It is a waterproof product that can be constructed on wet base surfaces.


Product Features
1. The base surface requirements are low, and the construction can be carried out on the wet base surface.
2. To shorten the construction period and save costs, two methods of wet laying and pre-laying can be used for construction.
3. The wet laying method can achieve full adhesion with the base surface, and the pre-laying method can achieve full adhesion with the structure, reliable bonding, safety and environmental protection.

Product Usage
1. Waterproofing of basements and roofs of industrial and civil buildings.
2. Suitable for waterproofing of subways, highways, railways, bridges and tunnels.

Storage and transportation
1. The coil is stored in a ventilated environment, and the storage humidity is not higher than 45 ºC;
2. Coils of different specifications are stacked separately;
3. Coiled material transportation shall not be inclined or cross-pressed, and cover with tarpaulin if necessary;
4. The storage period is 1 year from the date of production.
