Rubber Waterstop is widely used in construction concrete joints.It is to reach waterproof standards of construction joints, by increasing combination areas of two concrete construction / placement.
Waterstop types:
According to different raw materials, waterstops can be classified into:
--rubber waterstop (natural rubber waterstop, neoprene / chloroprene waterstop, synthetic rubber waterstop, bentonite waterstop, EPDM waterstop)
--pvc waterstop
--steel waterstop
--rubber waterstop with steel edge
Bentonite waterstop has the features of water expanding, water hydrophilic and swelling. This hydrophilic waterstop has better performance in construction joint sealing.
Applications:
Ideal for construction, control and expansion joints, on grade joints at wall or slab junctions, in industrial fields.
--Dams, locks, canals, water reservoirs and aqueducts.
--water and waste water treatment facilities
--primary and secondary containment structures
--storage tanks
--bridge and deck abutments
--slabs-on-grade
--culvert and tunnels
--retaining walls
--foundation
--parking garages
Features:
--high tensile strength and good elasticity
--corrosion and weather resistant
--can withstand high hydrostatic pressure
--can bear shocks of heavy turbines, earthquacks and floods etc.
--easy and quick operation
--waterproofing, good sealability
--low cost, comparing with steel waterstop
Demension:
Length:Usually 20m or 25m per roll.
Width:150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm etc.
Thickness:3mm-20mm.
Costomized demensions are available
Section profile:
Dumbell, dumbell with center bulb, ribbed flat, ribbed flat with center bulb, ribbed with tear web, base seal, split waterstop, cap waterstop etc.
It need to confirmed as per client detailed drawing, can be customized
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.
