SikaGrout® HES is a ready-mixed, Class C shrinkage-compensated cementitious grout that sets rapidly with high early strength gain. It suits jobs that need strength back in service fast: machine base plates, anchoring, starter bars, bridge bearing pads, precast panel grouting, and cavities. The grout does not segregate or bleed, and it is non-corrosive to steel or iron.
What is SikaGrout HES used for?
Machine base plates, anchoring, starter bars, bridge bearing pads, precast panel grouting, and cavities, gaps, and recesses where rapid strength and return to service are required.
How fast does SikaGrout HES gain strength?
It sets fast and builds high early strength, so equipment can go back to work sooner. The full strength timeline is in the technical specifications.
How much water do I add?
Flowable: 3.2 to 3.5 litres per 20 kg bag. Trowellable: 2.5 to 2.8 litres per 20 kg bag. Pot life is about 20 minutes at 23°C.
- Suits: Concrete structures and elements for machine base plates, anchoring, starter bars, bridge bearing pads, precast panel grouting, and cavities, gaps, and recesses. Steel and iron fixings: the grout is non-corrosive.
- Prepare: Surfaces must be sound and clean. Follow the product instructions before placement.
