Cemkrout GPH high strength non-shrink 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 thickness up to 100mm. 
Cemkrout GPH 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.

Uses

Cemkrout GPH is used for general purpose grouting where it is essential to eliminate shrinkage when completely filling the void between a base plate/formwork and a substrate. Such an application would be the grouting if a stanchion base plate structural reinstatement works and heavy machinery stabilization work. It can also be used for anchoring a wide range of fixings. These include masts, anchor bolts fence posts and bridge plates

Advantages

  • Gaseous expansion system compensates for shrinkage and settlement in the plastic state
  • No metallic iron content to cause staining
  • Prepackaged grout overcomes potential on-site. 
  • Develops high early strength without the use of chlorides.
  • High ultimate strength and low permeability ensure the durability of the hardened grout.
  • Against carbon dioxide and chloride diffusion.
