Strugrout E760
Expanding Cementitious Construction Grout
Strugrout E760 cementitious grout is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a flowing non-shrink grout for gap thicknesses up to 100 mm. Strugrout E760 is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimizing water demand. The low water demand ensures high early strength. The graded filler is designed to assist uniform mixing and produce a consistent grout.

- Pre-soaking: Flood the area with fresh water for a minimum of 2 hours prior to grouting.
- Base plate: Ensure it is clean and free from oil, grease or scale.
- Leveling shims: Treat with a thin layer of grease if they are to be removed after hardening.
- Formwork: Construct to be leakproof.
- Unrestrained surface area: Keep to a minimum.
