Application
APPLICATION INSTRUCTIONS
APPLICATION METHOD / TOOLS
General
Only butt joints should be formed on site with Sika Waterbars PVC-P Type V.
Prefabricated formpieces:
Standard formpieces (flat or vertical) for Sika Waterbars PVC-P Type V include: Cross pieces, T-pieces, Lpieces.
Prefabricated formpieces help to reduce the required butt joints on site to a minimum.
Special formpieces:
Combined formpiece systems using combinations of different standard connections and profiles. The standard maximum total length of formpiece system is 20m maximum. Longer formpiece systems on request.
Handling:
▪ Careful transport and handling on site
▪ Installation at ambient and waterbar material temperatures ≥ 0°C
▪ Protection until the waterbar system is fully cast in the concrete
▪ Special care must be taken with the waterbar system ends
▪ Waterbars must be cleaned before casting in
Application:
▪ Internal waterbars are to be installed within the concrete section and clearance from the edge of the concrete must be at least half of the total width a of the waterbar
▪ Detailed information on installation is given in the relevant method statement and instruction for use. If there are very high stresses or difficult concreting conditions, the waterbars can be combined with integrated injection hoses installed locally on the lateral anchoring ribs to additionally inject / grout around the cast-in parts at a later date.
Jointing on site:
The Sika Waterbars PVC-P Type V are butt jointed by welding. Jointing with adhesives is not permitted. Requirement: Minimum ambient temperature + 5°C and dry weather conditions. Site joints must be formed only by trained and qualified personnel.
