Product Introduction

Product Description

In the 1970s, with the continuous development of global economic construction, the rapid rise of the construction industry, and the requirements for waterproof coils are further improved, so manufacturers try to add high-polymerization SBS or APP and other modifiers in asphalt to improve the high and low temperature performance and durability of waterproof coils.
In the 1980s, the progress of the chemical industry and the diversification of architectural styles made PVC, TPO, EPDM and other polymer waterproof materials were born one after another.
HDPE polymer waterproof coil and pre-laid anti-sticking application technology, the earliest in the United States, Europe (Italy), Russia has production and application, mainly used in underground buildings, subways, tunnels and other projects. It was introduced into China by an American company in the 1990s, and has been praised by the subway design, construction and construction parties. With the expansion of the building scale, the change of the building structure, especially the increase of high-rise buildings, the traditional building waterproof materials can not meet the needs of the project, so that the polymer waterproof materials and its pre-laid anti-stick technology in the roof, wall, underground waterproof engineering has been applied, improve the waterproof function of the building.

Details

Installation:

1. Ensure the substrate is clean and dry before installation.
2. Peel off the release film from the self-adhesive tape and apply the membrane to the substrate.
3. Press down firmly on the membrane, ensuring it is fully bonded to the substrate.
4. Inspect the installation for any damages and repair as needed.
