Jian Guo An Zhu 45# Cement-based penetrating crystalline waterproofing agent
It is a high-tech, environmentally friendly, non-toxic polycarbonate active silica. When sprayed onto the concrete surface, it chemically reacts with the free alkali in the concrete to form a stable, vine-like crystalline gel. This effectively blocks the capillary pores inside the concrete, giving the concrete structure a lasting waterproof function and better density and compressive strength. The penetration depth reaches 20-50mm, and it can also effectively prevent the erosion of concrete by acidic substances, oil stains, and engine oil.
