DESCRIPTION
RB-RH is formulated to be used in applications where high compressive strength is prime goal such as installation of heavy machineries with high vibrations.
RB-RH is ready to use mortar with all necessary additives, only on-site addition of water is required to prepare smooth mortar. For all grouting, anchoring or injection purposes the inter surfaces should be cleaned and pre-wetted and then the mixed mortar should be placed or injected.
RB-RH is supplied in 25kg bags.

As the water consumption is at minimum rate (4.5 – 5.25 liters per a 25 kg bag) curing is essential in order to avoid surface cracking. In moderate temperatures curing should be continued for 3 days. In this way blow holes and minor blemishes in an otherwise fair faced concrete can be hidden.
RB-RH should be laid at a minimum thickness of 1 mm and to a maximum depth of 150 mm.
Should be stored in original bags and protected from excessive compaction, direct sunlight and rainfall, in this situation the shelf life exceed 12 months.
RB-RH is not a fire or health hazard. Spillages should be washed down immediately with cold water. For further information refer to the material safety data sheet.
