PVC water stops are used in concrete joints subjected to hydrostatic pressures. After being embedded in concrete, PVC Water-resistant belt fill up the joints to form a continuous watertight diaphragm that prevents the passage of fluid. The water stop must be designed and installed properly to accommodate joint expansions, contraction and lateral & transverse movements. In addition to these considerations the water stop must be compatible with the concrete system and the liquids and chemicals to be contained or controlled.
Slecting waterstop shape:
Ribbed with Centerbulb shapes are the most versatile type of waterstops available. The centerbulb accommodates lateral, transverse, and shear movement. Larger centerbulbs will accommodate greater movement.
Dumbbell with Centerbulb shapes accommodate lateral, transverse, and shear movement. Larger centerbulbs will accommodate greater movement. Consider using Ribbed with Centerbulb for better sealing characteristics.
Base Seal with Tear Web shapes accommodate lateral, transverse, and shear movement. Larger centerbulbs will accommodate greater movement. Base Seal waterstops have some limitations with transitions and intersections.
Flat Ribbed shapes are preferred for nonmoving joints and provide the best sealing characteristics.
Dumbbell shapes are an alternate profile for nonmoving joints. Consider ribbed shapes for better sealing characteristics.
Base Seal is ideal for slab-on-grade joints or backfilled walls and are easy to form. Base Seal waterstops have some limitations with transitions and intersections.

Applications of PVC Waterstop
It is used to almost every strategic concrete structure such as Dams, Canals, Over Head/Under Ground Water Tanks, Swimming Pools, Basement, Bridges, Road Embankments, Retaining Walls, High-rise buildings, Multi-storeyed Buildings.
Advantages of PVC Waterstop
Its basic advantage is in its time of fixing. It works as a sealant and it is fixed on predetermined place while concrete slab is laid. It is easy to installing and easy to weld at site and at required angle & shape
PVC waterstops must be securely positioned in the forms to prevent deflection or misalignment during concrete placement. This is achieved by tying off the outer edge of the waterstop to adjacent reinforcing steel. Dacheng offers options to properly anchor PVC waterstop, including:
• Punched Flanges - most ribbed shapes can be provide with punched flanges
• Grommets - select shapes can be provided with brass grommets
• Hog Rings and Pliers - available for field application and suitable for most shapes
Virtually every concrete structure requiring a PVC waterstop is going to encounter a joint that will change direction or intersect with another joint. One of the benefits PVC offers is the ability to heat weld the material to create a continuous sealing diaphragm within the joints of a concrete structure. Waterstop failures are often the result of field fabricated transitions and intersections. To avoid potential problems, strongly recommends factory fabrications and maintains an inventory of the most common fabrications to meet the demands of a construction schedule. Splicing irons are available in a variety of sizes for field welding lengths of PVC waterstop.
