Product
The water-expanding sealant strip is also known as the water-expanding rubber sealant strip for use in situations where water comes into contact with it. It is a strip-shaped sealing material with water-expansion properties, which is made through compounding and extrusion using more than ten types of materials.
The water-expanding sealant strip has a high expansion rate and strong self-repairing ability. When placed at the construction joint, it has a strong self-healing function and can seal new tiny cracks caused by settlement. For completed projects, if there is leakage due to gaps, this sealant strip can be used to re-seal the leakage. The cost of using this sealant strip is low, the construction process is simple, and its corrosion resistance is the best.
▍Characteristics
1. Reliable waterproofing: It has reliable waterproofing performance. The water expansion rate is high, it can seal and block leakage sources, achieving active and complete water stoppage.
2. Construction safety: Good balance self-healing function, strong mobility and replenishment ability, it can seal new tiny cracks caused by settlement by itself.
3. Construction convenience: Good plasticity, light weight, easy adhesion and positioning, easy to operate in narrow spaces.
4. Wide applicability and environmental friendliness: Under restricted conditions, it can be used without aging, non-toxic, non-corrosive, with a long-lasting water stoppage effect, and is the best choice for municipal environmental protection projects.
▍Application scope:
It is widely used in civil defense projects, swimming pools, sewage treatment projects, underground railways, tunnels, culverts, as well as other concrete construction joints, expansion joints and cracks.
