PVC Waterstop

PVC Waterstop is a waterstop material made of PVC polyvinylchloride resin and various additives through mixing, granulating, extrusion, and other processes. It has the elastic deformation of PVC resin, prevent leakage seepage in the building structure joints, with the characteristics of corrosion resistance and good durability.

Non Movement Joint	Movement Joint

Flat Ribbed Construction or contraction joints where little or non-movement. Better sealing than dumb bell shapes.	Ribbed With Center bulb The most widely used type. Center bulb accommodates lateral, transverse and shear movement. Larger center bulbs accommodate larger movement.

Dumbbell Construction or contraction joints where little or non-movement.	Dumbbell With Center bulb Accommodates lateral, transverse and shear movements.

Back Seal Ideal for slab-on-grade joints or walls which will be back-filled. Easy to form.	Tear Web Accommodates large movements, Upon joint movement the tear ruptures allowing the U-bulb to deform without putting them aterial intension

Swellable Waterstop

Swellable Waterstop is an absorbent strip used to seal and waterproof concrete joints. It is made of polymer expansion rubber. The synthetic rubber/polymer expansion rubber expands the joint when exposed to moisture. It is a new type of waterproof material, waterproof effect is more reliable than ordinary rubber. In contact with water the Swellable Waterstop will swell approximately 250%-600% of its original dry volume, the expansive clay mass will seal the cracks and small voids in the joint.
