Feature
High elasticity.
Capable to withstand hydrostatic pressure.
Adjust for subsidence and seismic movements.
Can arise compression deformation under various loads.
Adapt well to deformation and waterproof.
Wear, aging, corrosion, rust, tear resistance.
Setting holes ensure the waterstop fix with the nearest steel bar convenient and firmly.
Temperature range from -45°C to +60°C.
Application
Buried rubber waterstop can be applied to various types of concrete structures to prevent liquid leaking in or out, such as dams, reservoirs, subway, culverts, tunnels, sewage treatment plants,
water conservation, subways, sluices, underground facilities, aqueducts, roof, irrigation canals, sea walls, etc.
