High Performance Expanding Rubber Water Stop Band (made in China)

Q:Can you describe about the concrete pvc water stop ?
A:Water stop being embedded in the concrete joints, acts as a continuous watertight diaphragm to prevent any seepage of liquids in constructions joints which are subject to hydrostatic pressure. It is designed for expansion or contraction joint; At the same time, it can accommodate lateral and transverse movements which make it capable to suit the moving joints.

Q:What are the features of pvc water stop?
A:The following are the features of pvc water stop:

1. Rubber waterstop will expand when getting in touch with water, so allowing it to come into closer contact with the concrete, creating a better water-stop result.

2. Different thicknesses structure is adopted for the cross section, which is divided into the high-strength area, the waterproof area and the installation area, allowing for uniform and reasonable stress for all portions.

3. At installation area add installing hole, it could facilitate fixed with adjacent reinforced, and not produce shifting. Construction is convenient, positioning installation is firm.

4. High quality meet even exceed the industrials standard.

5. Never discolor concrete.

6. No electrolytic action with surrounding metals.

7. Capable to withstand hydrostatic pressure.

8. Heat weldable in conjunction with electric splicing irons.

9. Withstand the expansion and contraction movement of the joints.

10. Capable to taking care of any deflection or displacement arising caused by temperature changing or differential settlement of foundation.

11. Supplied in coils for easy handling with high flexibility.

12. Easy to install by tethering the outer flanges of the PVC waterstop to adjacent a reinforcing bars.

Q:Please describe about the quality testing of joint after welding.
A:
Weld seam protruding rib was bright and full empty sag, no leakage welding slag, no bubble.
The strip folded 180 degrees with hands and the weld joints as much as possible into sharp corners. There will be no crack,no bubble and no traces of slag. If there are defects, re fusion with welding torch welding or cutting
