In Issue 13

Ronacrete products were used to repair the nurses’ accommodation at Grantchester House, a high rise block of flats situated at Addenbrooke’s Hospital, Cambridge. The windows needed replacing, and the facades required restoration.

Three components of Ronacrete’s concrete repair and protection system were used to carry out the repair.

Firstly, damaged concrete was removed and following preparation of the concrete and reinforcement, Ronacrete Standard Primer was applied to the steel and concrete. Once the primer was ready, RonaBond HB40, lightweight repair mortar, was hand applied to the required areas at depths between 30 and 75mm. The mortar was then trowelled to leave a nice smooth finish.

Once the repair was complete and the mortar had set and cured sufficiently, the concrete façades were coated with RonaBond Anti-Carbonation Coating WB. While the client opted to coat the facade in white, RonaBond Anti-Carbonation Coating WB can be pigmented to over 300 colours.
