SikaFix® PU

Flexible polyurethane grout

SikaFix® PU is a low-toxicity, two-component, 100 % solids, polyurethane foam. It will displace and stop flowing water, forming a tough flexible foam, firmly bonded to the concrete surface.

  • The final cured product is a non-toxic rubber foam similar to that used in shoe soles
  • High bond strength even to damp surfaces
  • Flexible and easy to use
  • Waterproofs and seals cracks quickly and efficiently
  • Ministry of Transport Québec (MTQ) acceptance

Consumption

Yield

1 L (33.8 US fl. oz) grout = ~25 L (6.6 US gal) foam (typical free expansion)
1 L (33.8 US fl. oz) grout = ~3 L (0.79 US gal) foam (typical contained expansion)

Note: Variation in crack/void configuration, injection conditions and end use will influence the yield.
Application steps

SUBSTRATE PREPARATION

Ensure that cracks contain moisture or have been pre-wetted. For low pressure injection, use Sika® Injection T’s or use Sika® Injection Ports. Install the fat end of the devices into 13 mm (1/2 in) holes.

CLEAN UP

Use SikaFix® Pump Flush, a non-flammable solvent, to remove uncured product from tools and equipment. Cured material can only be removed mechanically.
