Product characteristics

▲ Light bulk density, large telescopic strength and no water absorption (alternative materials such as three oils and four felt asphalt wood fir board) Environmental protection of products, simple construction, anti-seepage, anti-leakage and good water sealing effect.

▲ Corrosion resistance, aging resistance, high and low temperature resistance + 80 ℃ ~-45 ℃, no flow, no deformation, no brittle crack and long service life.

▲ The appearance of the special joint plate with vertical opening bubble structure is honeycomb-shaped, and the holes are evenly distributed. It can be tightly bonded with cement/sealant without roughing, and can be integrated to adapt to the change of natural shrinkage and enhance the sealing and water-sealing effect of the joint.
