By taking advantages of the high elasticity and compression deformation capability of rubber, it can elastic deformation under the various types of loads to meet the purposes of fastening and sealing, thus, effectively preventing water leakage and creepage from architectural structures and serving as shock absorber and cushion. In the design of large project, it can't continuous casting, or transmutation of groundwork or beton's component expansion caused by heat and contract ion caused by cold due to the change of temperature, so it must install water-stop strip to prevent water percolation outside construction joint, settlement joint, movement joint. It's mainly used for basic civil project which is provided with construction joints and deformation joints that are integrated with the concrete structures where in-situ concrete pouring is carried out, as well as for underground facility, tunnel and culvert, water launder, water dam and liquid storage structure and so on to order to ensure prolonged service life and quality of the civil projects.
