Concrete embeded PVC waters range
Vetostop PVC water stops is a range of concrete embedded PVC profiles that stop water passage through tortuous path and positive valve seal mechanisms. The profiles are precisely engineered to block water passage in concrete joints. Vetostop PVC profiles are extruded from virgin non-recycled elastomeric polyvinyl chloride rubber. The profiles are designed for both internal fixation and external fixation with the internal sections brass eyelets placed on the non effective sides of the sections to enable tying to steel reinforcement for efficient fixation during concrete pours. Heavy duty profiles are used where large sections or where concrete heights exceed 4 meters.
- 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
- Factory prefabricated junction pieces. Easy to join on site
- Resistant to a wide range of diluted chemicals including hydrocarbons
- Heavy duty sections with high inertia resisting bending during concrete pours
- ASTM D412-06a (2013).
- US Corps of Engineers CRD C 572.
- US Department of Agriculture Guidelines.
- BS2571-1990.
- Vetostop PVC 6 mm thick sections supplied in 12 Lm rolls
- Vetostop PVC10 mm thick sections supplied in 10 Lm rolls
Vetostop PVC range has an unlimited shelf life provided it is stored clear of ground in a dry and shaded place below 35ºC.
Design Criteria
PVC water stops choice follows the guidelines of EN BS8102:2009 and CIRIA report No. 139
Recommended Profiles
Center Fixation
-
Vetostop CE250: 250 mm wide centrally fixed with bulb for expansion joint.
-
Vetostop CC250: 250 mm wide centrally fixed profile for construction and contraction joints.
-
Vetostop RE250: 250 mm wide rear fixation for expansion joints.
-
Vetostop RC250: 250 mm wide rear fixation for construction and contraction joints.
-
Vetostop HC250: 250 mm wide centrally fixed heavy duty profile for construction and contraction joints.
-
Vetostop HE250: 250 mm wide centrally fixed heavy duty profile for expansion joints.
Usage Instructions
Vetostop PVC center fix profiles inside form-work should be tied by steel wires to the reinforcement through the eyelets in the edge flanges. Rear fixation profiles 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. Vetostop PVC range 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 Saveto technical departments for further details.
Junction Pieces
Full range of factory made junction pieces are available for all profi les, for the following:
Flat and vertical cross.
Flat and vertical T.
Corner pieces.
Flat L.
Other custom pieces can be made upon order to customer specifications.
Hot welding of PVC will generate acidic hydrogen chloride fumes, jointing should take place in a well ventilated area, or while wearing oxygen mask. Avoid breathing fumes. Wear a proper mask.
