Grouting, Fixing & Anchoring
Grout is a fluid form of concrete used to fill gaps. Grout is generally a mixture of water, cement, and sand, and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between tiles. Grouts are versatile construction materials used for structural stabilization and load transfer. Grouting mortars are free-flowing, high-strength cement or synthetic resin-based mortars used for filling of voids under machines and other structural elements as well as for the grouting of anchors. The particular characteristics of such mortars are optimal flowability without segregation, high early strengths and low shrinkage.
When comes to grouting of anchor, starter bars are normally used to tie reinforced masonry or concrete walls to slabs or footings, as designed by the engineer. Anchoring steel bars in concrete is needed when an additional structural concrete member is to be linked to existing structure or to increase the section of the existing structure.
