5.05 Super Density Grout

5.05 Super Density Grout is a specially designed, pre-mixed, ready to use, cementitious grout powder. The compound is a blend of fine cements, quality graded heavy sands and a set of admixtures. When the powder is mixed with water, a free flowing, anti-shrink, super density, high strength grout is produced, which will not segregate or bleed at the recommended water content.

5.05 Super Density Grout has a minimum set density of 3600kg/m3. Rockbond also manufactures a Super Density Grout version that has a minimum set density of 4000kg/m³. The grout is packaged in 25kg valve bags, or 25kg pails, and has a shelf life of 5 years.
