Rubber Water Bar Introduction
The product is in ordinary rubber water stop (when the joints or construction joint displacement,
cause clearance exceeds the scope of elasticity of materials, general rubber water stop the loss
of water stop function) on the basis of waterproof line adopts the water swelling rubber.To treat
water after inflation increased with water stop structure of tightness, thus raising the water stop,
waterproof performance, solved perplex the surrounding the leakage problem of people, is a new
type of waterproof material.The series of products have been widely used in more than 200 key
projects in the country, the use effect is good.
Rubber Water Bar Feature
1.1Waterproof line adopting expansion rubber, under the influence of water after the water swelling,
make its closer contact with concrete, stop water effect is better.Elongation at break 500 (%) rubber
and plastic material.
1.2Cross section structure of the thickness, divided into strong, waterproof and installation area, make
it reasonable to receive strength evenly in the parts.
1.3And shrinkage cavity walls as flat, plate mold clamp system during the construction of large contact
area, is not easy to dislocation.
1.4Additional mounting holes in the installation area, can make its easy fixed, and the adjacent steel does
not produce displacement, construction is convenient, reliable positioning installation.
