Product Description
1. Product Performance and Characteristic
This product is use of the high elasticity and compression deformation of rubber. It can produce elastic deformation in all kinds of load, and can fastening the seal. It playing an effectively role of prevent the construction component of water leakage, seepage, and shock absorption. So as to ensure that the service life of the engineering construction.
2. Product Usage
A. Mainly used for infrastructure projects, underground facilities, tunnels, water conservancy, metro project.
B. For the gate, dam construction, engineering, underground structures with adjustable concrete pouring.
In the process of water stops in positioning and concrete pouring, we should pay attention to positioning method and poured pressure, in order to avoid water stops punctured and the influence of water stops effect.
