Façade Concrete Repairs

Design Museum, Kensington, London, August 2026

Project overview

Concrete Repair Solutions were appointed by the Design Museum on Kensington High Street, London, to repair areas of deteriorating concrete on the building’s external elevations.

Concrete on the façade and roof edges had started to crack and spall as the reinforcement beneath began to corrode. Our team removed the defective concrete, protected the steel, and rebuilt each area by hand to match the original concrete as closely as possible.

With the museum open to visitors throughout, the works were carefully planned around its day-to-day operation.

What we did

Access & Protection

Accessed the elevations by MEWP and rope access
Set up exclusion zones around each work area
Protected glazing and surrounding finishes

Sample Repair

Carried out a trial repair for approval first
Matched the colour and texture of the original concrete
Agreed the finish with the client before starting

Concrete Repairs

Removed defective concrete by hand
Cleaned and primed the exposed reinforcement
Rebuilt each repair by hand to the original profile

Protection

Applied a clear anti-carbonation coating over the repairs
Left the concrete’s appearance unchanged
Cleaned down and handed over each area

Technical overview

The Design Museum is one of London’s most recognisable buildings, so the repairs had to be both durable and visually sensitive. Every repair needed to blend in with the original exposed concrete.

Before the main works, a sample repair was carried out and approved, confirming the materials, colour and finish that would be used across the building.

At each location the damaged concrete was carefully removed and the reinforcement cleaned and treated against further corrosion. The repairs were then rebuilt by hand to match the existing profiles and texture.

A clear anti-carbonation coating was applied over the finished repairs, protecting them for the long term without changing the look of the concrete.

Project challenges

Working on a landmark building that stayed open to the public
Matching new repairs to the original exposed concrete
Reaching high-level roof edges and soffits safely
Keeping visitors and staff safe around the work areas

The outcome

All identified repairs were completed on 7 August 2026, with no defects or outstanding items at handover.

The repaired areas blend in with the original concrete, and the building is protected against further deterioration.

The museum stayed open throughout, and the works are backed by a 12-month workmanship warranty.
