Multi Grout CB-S
Ideal for Anchoring Into Soil or Rock
MultiGrout CB-S is a sanded, cement based non-shrink grout containing silica fume (microsilica) and other carefully selected additives. MultiGrout CB-S gains strength quickly and resists water washout making it ideal for anchoring tendons, cables and bolts into soil or rock media.
- MULTIgrout CB-S can be used for most grouted anchor requirements, including:
- Earth tiebacks for excavation and slope stabilization.
- Rock bolts or soil anchors in tunnel support systems.
- Cable bolting.
- Soil or rock tendons used for anchoring piles or foundation structures.
High early strength: MultiGrout CB-S has superior early strength gain compared to Type 30 grouts, allowing early tensioning of anchors. It has comparable strength gain to high alumina grouts, but does not experience strength regression.
Resistance to water washout: MultiGrout CBS has excellent cohesive properties. It resists washout or dilution by water and thus can be used in wet ground conditions and still retain its excellent physical properties.
Reduced Grout Takes: MultiGrout CB-S has thixotropic properties. It tends to get after placement or pumping. This gelling action prevents the loss of grout in porous or fractured geology.
Excellent Pullent Resistance: MultiGrout CB-S exhibits excellent pullent resistance for cable bolts and rock bolts due to the increased friction component imparted by the sand.
MULTIgrout CB-S is packaged in 30 kg, heavy-duty, polyethylene-lined bags. All MultiGrout CBS packaged materials can be custom packaged to meet specific project requirements.
MultiGrout CB-S contains Portland cement and carefully selected additives. Normal safety wear such as dust mask and rubber gloves used to handle conventional cement based products should be worn.
Adhering to recommended water additions is very important. Exceeding the maximum recommended water content per sack will result in inferior physical properties.
