一、Product Introduction

Cementitious nano permeable crystalline waterproof material is an inorganic catalyst composed of various functional additives modified nano polymer materials, special cementitious materials, and high-quality aggregates. It has excellent waterproof, anti-seepage, and self-healing functions. Cracks often appear in concrete structures under conditions such as earthquakes, geological subsidence, and temperature changes. Once water enters the concrete, it will react with the catalyst in the waterproof material. This further catalyzes the rehydration process of semi hydrated cement, forming water-insoluble crystals. These crystals penetrate into the cracks to a depth of up to 30 centimeters, and over time, the cracks undergo infinite self repair, ultimately completely sealing off the water seepage channel, thereby enhancing the waterproof performance of the concrete structure. This self-healing ability not only continuously improves the waterproof performance of concrete, but also strengthens the concrete structure. It is worth noting that the ability to self repair concrete cracks is a function that other waterproof materials currently on the market do not possess. It can be widely used in waterproof repair and reinforcement engineering of damp concrete structures, especially suitable for places that require waterproof and anti-seepage construction such as tunnels, subways, dams, basements, sewage treatment plant pipe pools, dock caissons, docks, etc. It is also suitable for waterproof repair of kitchen, toilet, roof, and exterior walls of civil buildings.

二、Main characteristics

Strong permeability, with a penetration depth of up to 30cm in concrete cracks, able to withstand strong water pressure for a long time;

It has permanent waterproof function and self-healing ability, and can have the same lifespan as concrete.

Convenient construction, can be carried out on damp surfaces and under low temperature conditions, and can be carried out on the upstream and downstream surfaces of leakage points;

Corrosion resistance, high temperature resistance, low temperature resistance, aging resistance, can enhance the durability of concrete;

Non deteriorating, earthquake resistant, non-toxic, harmless, odorless, and environmentally friendly;

High adhesion strength and good affinity with various wall substrates;

Stable quality, easy construction, can be sprayed or applied directly by mixing with water;

It can block the infiltration of water without affecting the breathing of concrete, making the concrete structure dry and not damp.

三、Application scope
