Application

Swimming pool.Sewage treatment works.Tunnel.Subway.Railway.Basement.Underground garage.Storage tank.Power plant cooling tower.Wall seam.The construction joints, expansion joints, cracks of concrete works. Installation tips:

The storage and transportation of waterstop should avoid moisture and extrusion deformation. Before the next concrete pouring, the construction joints that have appeared all should install the waterstop. The construction joints and after pouring seam that need to fix waterstop should keep dry. And you should clear the scum, dust and debris on interface. After determining the installation site of waterstop, we should apply a thin layer of adhesive on the interface where the waterstop is to be installed and on the bottom of the waterstop. And we should paste after a period of volatility. We also can fix the waterstop on the mounting area with high-strength anchor. In case of concrete interface is damp or uneven, adhesive paste fixed is not strong, we can further strengthen the fixed with strong nail depending on the specific situation. In short, the PN unvulcanization waterstop must be in close contact with the concrete interface and fix closely to prevent PN unvulcanization waterstop out of the interface and lose impermeability. After installing the waterstop, it should be poured with concrete. The thickness ＞50 mm. The connection of waterstop should be connected in overlapping methods. It should be fixed with high-strength nails after pasting. The installation path forms a closed loop along the construction seams without break points. Before pouring the next concrete, the PN unvulcanization waterstop should avoid being soaked in water and other submerged water.

Steel-edge Waterstop Ideal for Deformations Joints

How Steel-Edge Waterstop Works To Proof Liquids? Steel-edge waterstop is a modification of traditional rubber waterstop with steel plate rings being inserted into the middle of vulcanized rubber. High liquid-tightness and high absorption of shear movements make the steel-edge waterstop a recommended choice for expansion, contraction joints and other construction fields with high pressure and structure variable.

https://www.jointwaterstop.com/product/steel-edge-waterstop.html

Once the structure sedimentation, concrete shrinkage and creep occur, the rubber parts of steel-edge waterstops will be elongated and thin to adjust to these deformations without affecting the adhesion between steel plates and the rubber part, between steel plates and the surrounding concrete. In this way, the steel-edge waterstops are able to withstand greater tension and torsion than traditional waterstops; meanwhile, it effectively prevents concrete loosen, breaking off and the form of leaking cracks.
