一、Product Introduction

This product is a waterproof repair material with certain impermeability properties made by mixing a variety of functional additives modified polymer, special cementitious materials, and high-quality aggregates in proportion. The production and use process is non-toxic, pollution-free, environmentally friendly, with good adhesion to the base, good fluidity, no shrinkage, and good crack resistance. Widely used for waterproof repair and reinforcement of damp concrete structures, especially suitable for waterproof and anti-seepage construction of tunnels, subways, dams, etc.

二、Main characteristics

Good adhesion performance, compactness, and waterproof performance;

Convenient construction, can be carried out on damp substrates and under low temperature conditions;

Corrosion resistance, high temperature resistance, low temperature resistance, and aging resistance;

Non deteriorating, earthquake resistant, non-toxic and harmless, odorless, green and environmentally friendly. If there is no human or structural damage, it has the same lifespan as the building;

High adhesive strength and good affinity with various wall substrates (such as coatings, tiles, etc.);

Stable quality, easy construction, and can be applied by directly adding water and stirring on site;

A good interface layer is formed on the surface layer, which facilitates subsequent construction. Save labor and time, reduce overall costs.
