Features of water-swelling waterstops for tunnels: Slow-swelling waterstops will gradually expand when exposed to water. On the one hand, they will block possible capillary pores, and on the other hand, they will make the contact between the concrete interfaces closer, resulting in It has a large resistance to water pressure and forms an impermeable plastic colloid.
This waterstop has a high expansion rate and strong movement supplementability. It is placed in the construction joint and has a strong balance and self-healing function after the joint is post-poured. , can self-block new tiny gaps that appear due to settlement. For completed projects, such as water leakage from gaps, this product can be used to re-block the leaks. The cost of using this water-stop strip is low, the construction process is simple, and it has the best corrosion resistance. good.
, high expansion ratio and strong mobile supplementation. The waterstop placed in construction joints and post-cast joints has a strong balance self-healing function and can self-block new micro-cracks caused by settlement.
The waterproof and anti-seepage effect is better than that of traditional steel plates, rubber and plastic waterstops, and the construction method is simple and easy, saving labor and time.
The main material of the product is inorganic mineral raw material, which has the characteristics of aging resistance, corrosion resistance and pollution-free. Suitable for water-stopping of concrete construction joints and post-pouring joints.
