Concrete repair to Brighton art-deco appartment block


Repairs to the concrete façade of an art deco apartment block on Brighton sea front were carried out using RonaBond HB40 and RonaBond Flowable Micro Concrete.

Astra House is an Art Deco apartment block built in 1938 and situated on Kings Road on Brighton’s sea front.

The building houses commercial premises on the ground floor with 61 flats above. Decades of exposure to salt spray had corroded the reinforcement in pre-cast concrete façade panels causing spalling of concrete.  Despite several repairs over the years cracks continued to appear, eventually causing pieces of concrete to fall from the building.

Ronacrete Approved Contractor Constructive Solutions carried out a survey to establish what repairs were required and they were then contracted to remove the damaged concrete and debris from old repairs and to carry out the necessary repairs to the panels.  After removal and replacement of all reinforcement, RonaBond HB40 high build repair mortar was used to reinstate the concrete to the façade panels.  RonaBond Flowable Micro Concrete was used to re-form damaged sills.

RonaBond HB40 is a pre-packed high build, medium strength repair mortar for repairing concrete and protecting reinforcing steel. It is used to repair concrete facades and soffits, where its combination of ease of application and strength makes it an ideal product. RonaBond HB40 can be applied in thick-section layers up to 50-75mm on walls and 30-50mm on soffits, maximum layer thickness is dependent on the size of a repair.

RonaBond Flowable Micro Concrete is a repair concrete used in place of hand applied mortars to repair and replace sections of concrete. Designed for pour and pump application, the material is poured into shuttering to reform concrete profiles. It is shrinkage compensated and provides high early and ultimate strengths.

The residents were very pleased with the concrete repair work carried out by Constructive Solutions. It was part of a general refurbishment of the building which was overseen by Brighton and Hove Council and included interior and exterior refurbishment.
