Four stages of concrete repair at St Saviours’ Estate

Four stages of concrete repair at St Saviours’ Estate

Repairs to six blocks of flats were carried out by Ronacrete Approved Contractor Gunite (Eastern) Ltd for Lengard on behalf of Southwark Council. They used products from the Ronacrete RonaBond Concrete Repair & Coatings range.

The refurbishment was carried out on six blocks of five, six and seven storey residential flats at St Saviours Estate, London SE1. The project required repairs to the fabric of the buildings.

Gunite cut out and prepared areas of damaged concrete, primed the exposed reinforcement with Ronacrete Standard Primer and then re-primed the reinforcement when the concrete was primed, before applying RonaBond HB40 high build polymer modified mortar.

The repaired areas were then made ready for decorative and protective coatings by the application of RonaBond Easy Skim FC. This is a pre-packed polymer modified mortar which is applied as a skim coat in thicknesses up to 3mm, to provide a smooth, hard finish to damaged, blemished and repaired concrete. It is a levelling mortar that provides a smooth “harder than plaster” finish to walls.

The final stage involved the application of decorative and protective coatings to the repaired surfaces. Two products were used at this stage, RonaBond Crack Bridging Anti-Carbonation Coating WB and RonaBond Anti-Carbonation Coating WB.

The RonaBond products greatly improved the integrity of the concrete and appearance of the flats on the St Saviour’s Estate, as well as providing protection from further corrosive damage for years to come.
