plastic pvc waterstops - ws

Rubber waterstop is widely used in various types of concrete structures, such as: dam, reservoir, subway, tunnels, tunnels and other underground engineering. In these works, due to the continuous casting, or due to foundation deformation, or due to temperature changes caused by heat expansion and cold contraction of the concrete component and other reasons, the cast often have deformation joints, construction joints, the seam leakage problem should be adopted in the deformation joint parts casting rubber sealing strip method to solve, it can prevent the groundwater or outside water leakage into the building structure, and can prevent the rubber waterstop construction within the water leaking to the outside.

Detailed Product Description

1. Superior in rubber high elastic and compression deformation
2. Produced under elastic deformation in variety load.
3. prevent the construction component, and the water leakage, seepage, with the characteristics of tighten seal effectively
4. Having great shock absorption function to ensure the rubber-sealing belt engineering building service life.
5. Excellent quality and reasonable price and obtained highly prize of the Industry experts.

6. High tensile strength, elongation at break, anti aging properties
