PVC Waterstop - The Best Solution to Concrete Construction

PVC waterstop, 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; meanwhile, it can accommodate lateral and transverse movements which make it capable to suit the moving joints.

The PVC waterstop is extruded form an elastomeric plastic material including high grade polyvinyl chloride, special resin and some chemical additives such as plasticizers and stabilizers. The high material makes PVC waterstops unsurpassed with a variety of features and benefits as shown follow.

Features & benefits:

Four types of PVC waterstop in blue, gray and yellow
PVC waterstops
  • High tensile strength.
  • Superior elongation capability.
  • Excellent inherent elasticity and impermeability
  • High resistance to acids, ozone, seawater even diesel oil.
  • Extremely alkalis, chlorinated water and other waterborne chemicals resistant.
  • Not susceptible to fatigue deterioration as with metal or rubber.
  • High quality meet even exceed the industrials standard.
  • Never discolor concrete.
  • No electrolytic action with surrounding metals.
  • Capable to withstand hydrostatic pressure.
  • Heat weldable in conjunction with electric splicing irons.
  • Withstand the expansion and contraction movement of the joints.
  • Capable to taking care of any deflection or displacement arising caused by temperature changing or differential settlement of foundation.
  • Supplied in coils for easy handling with high flexibility. 
  • Easy to install by tethering the outer flanges of the PVC waterstop to adjacent a reinforcing bars.

Applications:

Four types of methods for easy fixing PVC waterstop including punched flanges, brass eyelets, hog rings and clamps.
PVC waterstops with punched flanges, grommets, hog rings or clamps for easy installation
  • Ideal for movement joints.
  • Suitable for above or below grade applications.
  • Suitable in portable water tank.
  • Water and sewage treatment facilities.
  • Liquid retaining structures such as dams, canals water reservoirs, lock and aqueducts.
  • Tunnels and culverts.
  • Foundations and basements.
  • Parking decks, bridge decks and abutments.
  • Elevator pits, roof and floor slabs.
  • Primary and secondary containment structures.

Installation:
In general, the right way of waterstop installation determines the performance in preventing waters and other waterborne chemicals. Any deflection and misalignment should be avoided - that means the best way of installation is to fix the PVC waterstop to the surrounding steel. So for easy installation, three economical methods are provided by our company as shown in the picture:

  • Punched flanges
  • Grommets
  • Hog rings or clamps
