Where are waterstops used?

——The concept and classification of waterstops

Waterstop is a sealing material mainly composed of rubber, polymer, and metal materials. According to the different materials, waterstops are divided into various types such as rubber waterstops, polymer waterstops, PVC waterstops, and metal waterstops. Different types of waterstops are suitable for different building scenarios and engineering requirements. Waterstops are often used for waterproof sealing of buildings such as basements, pipeline tunnels, dams, reservoirs, rivers, bridge piers, and tunnels to prevent the infiltration of groundwater and rainwater, avoid structural damage, and prevent road collapse. In addition, waterstops can also be used inside concrete structures, such as concrete deformation joints and expansion joints. They utilize the high elasticity and shrinkage properties of rubber to produce elastic deformation under different loads, thereby playing a sealing role, effectively preventing water leakage and seepage, and having a shock-absorbing effect to extend the service life of engineering buildings.

The purpose and function of waterstops

1. Prevent water leakage

In construction projects, waterstops are mainly used for waterproofing, which can prevent groundwater or rainwater from seeping into the interior of buildings and keep them dry. The waterproof effect of waterstops is particularly evident in basements, water pools, tunnels, and other places.

1. Isolate the water level

Waterstops can also be used to isolate water levels. For example, when constructing water conservancy projects such as dams, water gates, and river barriers, it is necessary to set up waterstops above the water level to prevent water from seeping through the waterstops.

1. Enhance resilience

Due to its high strength, elasticity, and toughness, waterstops can enhance the toughness and crack resistance of building materials, thereby improving the overall stability of buildings.

1. Prevent corrosion

In marine engineering and chemical industry, waterstops can play a role in anti-corrosion and corrosion prevention, extending the service life of buildings.
