Description

RocBuild HF is a single pack structural grade, polymer modified, fiber reinforced cementitious repair mortar. RocBuild HF is a high strength reinstatement mortar with shrinkage compensating properties. The product is ready to use, requiring only the on-site addition of water.

RocBuild HF consists of a blend of Portland cement graded silica sands, styrene polymers, non-asbestos fibers and shrinkage control agents. Drying shrinkage is controlled to ensure complete void filling and therefore effective load transfer. RocBuild HF is a quality controlled repair mortar that exhibits low slump characteristics coupled with remarkable ease of application. The presence of a polymer ensures an excellent bond to most surfaces and improves such properties as impermeability, flexural and tensile strength. Cellulose fibers improve water retention to aid complete hydration of the cement.
