Rubber WaterBar Introduction

The product isin ordinary rubber water stop (when the joints or construction jointdisplacement, cause clearance exceeds the scope of elasticity of materials,general rubber water stop the loss of water stop function) on the basis ofwaterproof line adopts the water swelling rubber.To treat water after inflationincreased with water stop structure of tightness, thus raising the water stop,waterproof performance, solved perplex the surrounding the leakage problem ofpeople, is a new type of waterproof material.The series of products have beenwidely used in more than 200 key projects in the country, the use effect isgood.

Rubber WaterBar Feature

1.1Waterproofline adopting expansion rubber, under the influence of water after the waterswelling, make its closer contact with concrete, stop water effect isbetter.Elongation at break 500 (%) rubber and plastic material.

1.2Cross sectionstructure of the thickness, divided into strong, waterproof and installationarea, make it reasonable to receive strength evenly in the parts.

1.3And shrinkagecavity walls as flat, plate mold clamp system during the construction of largecontact area, is not easy to dislocation.

1.4Additionalmounting holes in the installation area, can make its easy fixed, and theadjacent steel does not produce displacement, construction is convenient,reliable positioning installation.
