General
Only butt joints should be formed on site with Sika Waterbars PVC-P Type DR.
Prefabricated formpieces:
Standard formpieces (flat or vertical) for Sika Waterbars PVC-P  Type DR include: Cross pieces, T-pieces, L-pieces.
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:

• The overhall width of the Waterbar should be at little less or equal to the thickness of the concrete slab into which it is placed.
• The overall width of the Waterbar should be at least six times the size of the largest aggregate used.
• External waterbars are to be installed on the surface of the formwork or on the surface of the base of dry clean concrete.
• 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 DR 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.
