Cressy House - Structural Renovations Concrete Repairs

Cressy House

Structural Renovations commenced work in October this year at this purpose built residential development, comprising 3 linked blocks, in southwest London.

Our brief was to survey, prepare and repair the exposed faces of the reinforced concrete slabs, which form the floors and roof.

Previous repairs and coatings had deteriorated, together with additional defects that had developed since the last maintenance scheme and the survey identified extensive damage.

All defective concrete was removed back to sound material and the edges square-cut to prevent feather-edging. Any exposed reinforcement was cleaned of corrosion before being treated with 2 coats of corrosion preventative primer. The prepared defects were reinstated using a polymer rich, cementitious repair mortar, back to the original surface profile.

Following completion of repairs the previously decorated concrete was pressure-washed to remove loose and failed coatings, to form a stable substrate, upon which a coat of water based, epoxy modified surface primer was applied. The primed surfaces were then treated with 2 coats of a pigmented, anti-carbonation coating to afford protection to both repaired and existing concrete but also to provide a uniform aesthetically pleasing finish.

The works were accessed from a fixed scaffold and completed within a restricted programme period, to the satisfaction of our client.
