Water expansion sealing strip product introduction
Release time:
2025-01-20
Water-swelling rubber putty not only possesses the good adhesion and low-temperature performance of general putty, but also has excellent expansion characteristics. This product is synthesized from various polymer chemical materials, offering higher strength than regular putty, making it particularly suitable for waterproof projects. The product can be produced in specified models according to user and design requirements, and the finished product is generally wound into rolls and packaged in cardboard boxes for convenient transportation.

The water-swelling expansion water stop strip has a high expansion ratio, strong mobility, and a strong self-healing function when placed behind construction joints, capable of sealing new small cracks caused by settlement. For completed projects, if there is water leakage due to joint penetration, this water stop strip can be used to reseal. Using this water stop strip is cost-effective and the construction process is simple, with optimal corrosion resistance. It is widely used in civil defense, swimming pools, sewage treatment projects, underground railways, tunnels, culverts, and other concrete engineering construction joints, expansion joints, and cracks.
