Features:

A. Good hydrophobicity and chemical stability.
B. With large permeation radius,solidification volume ratio and high water reaction rate.Reacting with water can release a lot of expansion pressure which push the slurry to diffuse to the depth of the crack to form a tough consolidation.

C. Good chemical corrosion resistance against acid, alkali and organic solvents.
D. Excellent adhesion with concrete base and other building materials.
E. The viscosity and curing rate of grouting material can be adjusted according to engineering requirements.

Application:

A.Filling seam sealing and waterproof anticorrosive coating of Water tank, water tower, basement,shelter and other buildings.

B. Corrosion protection of metal and concrete pipe layer and steel structure.

C. Foundation reinforcement of underground tunnels and buildings and ground dustproof treatment.
D. The sealing and strengthening of  seams, construction joints and structural cracks in construction projects.
