Buildings Repairs & Refurbishment Concrete Repair Coatings Cleaning & Preparation External Façade Refurbishment Projects
Thackley End comprises four residential apartment blocks located at 119 Banbury Road in the Summertown area of Oxford, a predominantly residential setting. The buildings are of reinforced concrete construction and feature communal external stairwells with glazed panels, covered walkways, flat roofs, and private rear balconies.
Over time, the external concrete surfaces had suffered from carbonation, compounded by the deterioration of an existing anti-carbonation coating and historic localised repairs. To protect the structural integrity of the assets and maintain their appearance and safety, a programme of concrete repairs and recoating was required. The works were designed to address ongoing degradation and support the long-term asset management strategy for the buildings.
Removal of existing anti-carbonation coating using KEIM Paint Stripper
Pressure washing of external concrete surfaces
Removal and replacement of defective construction and building joints
Ancillary spot repairs to building fabric
Removal of defective concrete
Repair of defective concrete
Application of KEIM anti-carbonation coating to all external concrete surfaces
Application of multi-seal self-adhesive to building joints
Concrete Repairs Ltd (CRL) undertook the works as a coordinated package, combining specialist access, surface preparation, concrete repairs, and protective coating application. Site establishment included offices, welfare facilities, and storage areas to support safe and efficient delivery. Access to all elevations was achieved through the organised delivery and erection of scaffolding, supplemented by MEWPs where appropriate, allowing controlled access to stairwells, walkways, balconies, and external walls.
The existing anti-carbonation coating was carefully removed using KEIM Paint Stripper STS 7M, followed by thorough pressure washing to expose the concrete substrate. This process ensured that carbonation-affected areas, previous defective repairs, and latent defects could be accurately identified. Defective construction and building joints were removed and replaced, while ancillary spot repairs were carried out to address minor fabric defects.
Areas of defective concrete were broken out to sound material and repaired using appropriate concrete repair techniques to reinstate cover and structural performance. These interventions were targeted and proportionate, ensuring that only affected areas were treated while maintaining programme efficiency. Once repairs were completed, a new KEIM anti-carbonation coating system was applied to all external concrete surfaces, providing a breathable yet protective barrier against further carbonation. Multi-seal self-adhesive was applied to building joints as instructed, ensuring continuity of protection across interfaces. CRL’s integrated approach demonstrates its expertise in concrete repairs and structural repairs UK, delivering technically sound solutions tailored to residential assets.
“Throughout the works, tenant liaison was managed to an exceptionally high standard. Vim, ensured that residents were kept fully informed of programme activities and any changes through regular notice board updates and letter drops. This proactive and considerate approach was greatly appreciated by both tenants and the client. "
Client's feedback
The reinstated anti-carbonation coating system provides long-term protection to the concrete façades by reducing carbon dioxide ingress while maintaining vapour permeability. Combined with the removal of defective joints, installation of new joint systems, and application of multi-seal self-adhesive, the works significantly enhance durability at vulnerable interfaces. Careful surface preparation, including chemical stripping and pressure washing, ensured optimal adhesion and performance of the new coating system.
By addressing carbonation-related deterioration and previous failing repairs, the programme reduces the risk of reinforcement corrosion and future concrete spalling. The outcome is a resilient external envelope with reduced maintenance requirements and an extended service life. CRL’s methodical delivery supports sustainable asset management, ensuring the buildings remain structurally sound, visually consistent, and protected against ongoing environmental exposure.
