PVC Waterstop

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:

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:

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

Elastomeric Rubber Bearing Pad China Supplier

Laminated Elastomeric Bearing Pads

Laminated elastomeric bearing features reinforced steel plates that are sandwiched between layers of rubber through vulcanization and molding manufacturing process to form a homogeneous unit. Not only do these embedded steel plates limit excessive expansions, but also increase transversal, longitudinal and compressive strength as well as rotation capability comparing with plain elastomeric bearings.

Features:

Laminated elastomeric bearing

• Capable to withstand severe vertical loads and external forces.
• High accommodation of movements caused by expansion, contraction, concrete creep effects and shrinkage, etc.
• Allow for rotations of the bearing in any horizontal axis caused by deflections or misalignments.
• Absorb vibrations and isolate sounds.
• Great traction resistance.
• Corrosion free in that the steel plates are embedded in the rubber without contact of air.
• Easy to install.

Applications:

• Bridges with small displacements and short span.
• Load bearings of building structures.
• Flyovers.

Types:

Normally, different shapes of laminated elastomeric bearings suit different types of applications. For example, rectangular bearings are ideal for orthogonal bridges, while round bearings are suitable for oblique crossing and cylindrical pier bridges. Round bearings with spherical surfaces are the best choice for curved bridges with 3% to 5% slopes.

Load distribution & movement accommodation of laminated elastomeric bearing

Details:

• Materials: quality natural rubber, neoprene or others to suit your scheme.
• Thickness: 1/8” to 30” or custom thickness.
• Width: 36” to 48” or custom widths.
• Shapes: rectangular, square or round (with optional holes for anchor bolts as your request).
• Hardness: 50 to 70 durometer complying with AASHTO.
• Standards: AASHTO, ASTM D4014, BS EN 1337 or other standards according to your requirements.
