Project Overview

The Lady Lever Art Gallery is a Grade II listed building and was built in 1922. King George V laid the gallery’s foundation stone in 1914.

The gallery is a reinforced concrete structure with exterior Portland stone cladding and asphalt roof covering. Over the past couple of years the building has been affected by rainwater ingress and damage to internal decorations. Our brief was to undertake a condition survey of the roof and items such as roof-lights, glazed lanterns and parapets and provide the Client with a phased repair strategy for the next 10 years.

Our investigations included:

  • Thermographic camera survey to identify trapped moisture beneath the asphalt covering.
  • Core samples through the roof to establish depth and type of insulation.
  • Sample testing of the concrete roof deck for the presence of harmful chlorides and corrosion of the steel reinforcement bars.

Scope of Works

The Client’s requirements were straightforward: to make the building water-tight and to increase natural lighting… but without damaging delicate tapestries and paintings.

JDB designed a package of works which included replacing the old glass roof-lights with new UV protected thermally efficient glazing systems. A new bitumen-felt roof covering ensured complete water-tightness and improved the thermal insulation of the roof deck. As an added bonus the new system can be laid directly over the existing asphalt – which greatly reduces the Client’s strip-out costs. Working with the contractor Fulwood Roofing Services (Northern) Ltd, Phase 1 of the works was completed in June 2013. All works are supported by 20 year insurance backed guarantees.
