KingStop 50®
PVC Waterstops
Overview
KingStop 50 is extruded from an elastomeric polyvinyl chloride rubber. KingStop 50 are designed in precision engineered profiles to stop any possible leakage from construction, contraction and expansion joints in cast-in- place concrete elements. KingStop 50 are produced in two profile ranges; one used for internal fixing and the other for external fixing. Both profiles can used in combination as an integrated system suitable for use in water retaining and water excluding structures. Internal fixing profiles have brass eyelets at 300mm spacing enabling the waterstop to be tied to the reinforcement for support during concreting. External fixing profiles can be fixed by using nails onto the form work or onto the blinding concrete.
Applications
- KingStop 50 is suitable for use in construction, contraction and expansion concrete joints in the following structures:
- Water reservoirs
- Waste water treatment plants
- Storage tanks
- Retaining walls, foundations, basements and suspended slabs
- Swimming pools
- Subways, tunnels and culverts
- Canals, pumping stations and underground chambers
- Foundations, basements and suspended slabs
Advantages
- Unique profile design with multiple ribs
- Has no effect on the quality of potable water
- Brass eyelets at 30cm spacing for more rigidity while concreting
- Hollow center bulb for expansion joints to accommodate movement
- Prefabricated junction pieces
- Easy to join on site
- Resistant to wide diluted chemicals including hydrocarbons
- STANDARDS KingStop 50 complies with BS 2782, and U. S. Corps of Engineers CRD- C 572-74 for the following properties:

KingStop 50 fixed external should be fixed before concreting with nails to the concrete blinding and vertical shutters through the edge flanges. SITE WELDING The key to a leak free waterstop network is correct on- site jointing. KingStop 50 is made of thermoplastic PVC, and can be easily welded using suitable heating processes, such as welding knife. Cut the edges to be welded in a sharp and straight line then secure the ends in a welding jig. Use the welding knife between the ends, until an even, molten bead appears. Remove the welding knife and press the ends firmly together. Consult KINGKRETE technical departments for further details.
