Southwark Estates - Structural Renovations

Southwark Estates

Structural Renovations have been awarded the contract by The City of London Corporation to verify the condition of the concrete on 10 residential blocks of flats in the Southwark, Southeast London.

The ages of the various blocks range between 65 and 90 years and are therefore some of the oldest flats in the area.

Although all the blocks appear to be predominantly constructed from brick, they do in fact contain significant quantities of reinforced concrete, in the form of public and private balcony supporting slabs, window surrounds, roof overhangs and lintels.

Our brief is to establish whether cast-in chlorides, combined with carbonation attack over time, has affected the condition of the buried reinforcement leading to cracking or spalling concrete which has the potential to compromise structural integrity.

The works will be carried out over an 8 week period, using specialist technicians working from mobile elevated works platforms, roped access techniques (abseil) and mobile towers.

Following completion of the site activities, a structural engineer’s assessment will determine the extent of necessary concrete repair and corrosion control. We will then develop and suitable specification, based upon one of the recognised concrete repair manufacturers repair systems.

This survey project will be completed whilst the blocks are live and therefore it is a requirement for us to ensure these works are completed in an efficient and timely manner, causing minimal disruption to residents.
