Barbican Structural Renovations Sealant

Barbican Estate

Structural Renovations Limited have completed a number of repair and waterproofing contracts for the City of London Corporation at the Barbican Estate.

We were initially asked to devise suitable remedial schemes for the differing issues being experienced at the Grade II listed site, where consideration needed to be given to residents, staff and the public and where noisy works were to be carefully programmed to suit all interested parties.

Our works to Speed House, Ben Jonson House, and John Trundle Court podia required us to isolate agreed locations, carefully lift the brick paving either side of the main movement joints and rake out all defective materials back to sound substrate. Following this preparation work we applied a 3 coat, glass fibre reinforced polyurethane membrane, dressed into the joint. The paving was subsequently reinstated and a new polyurethane jointing compound was used to reseal the joint and accommodate future movement in the structures.

Works at the rear of Lauderdale Tower, together with Wallside involved both waterproofing, to prevent ingress to the car parks below and repairs to exposed aggregate concrete, using a modified mortar containing the appropriate size, type and concentration of aggregate.

These projects, the last of which was completed this month mark the 10th successive year of working for the Estate, where we’ve built up a knowledge of the wide variety of structures, along with good working relationships with a number of the Corporation’s employee’s.
