Kings Hall Boundary Wall, Hackney

Consolidation & Repair

The historic brick boundary wall to the Kings Hall Leisure Centre in Hackney was in a state of disrepair, covered with overgrown vegetation and undermined by root systems and years of neglect. London Stone Conservation delivered a full programme of repair.

The public leisure centre was constructed in 1894, and along with the boundary wall are locally listed within the Clapton Square conservation area. The main building and public baths are also Grade II listed. The brick and mortar wall now forms a boundary between the leisure centre car park and a row or residential properties to Clapton Square.

In early 2018 London Stone Conservation won the tender to consolidate and repair the listed boundary wall for Hackney Council. The first phase of works was to clear the site of all organic growth and root systems, which included the removal of a large tree that was growing perilously close to the wall foundation. The overgrown appearance of the area had also led to illegal dumping and accumulations of detritus. With the area cleared and wall fully exposed, all surfaces were carefully cleaned with the DOFF superheated water system. The aim of the repair program was to stabilise the wall using sympathetic methods and materials, whilst maintaining as much of the original fabric as possible. The schedule included the localised consolidation of the existing foundation; deep tamping and grouting of voids; reinstatement of salvaged bricks; sourcing and replacement of reclaimed bricks to match; rebuilding of damaged areas; repointing and rebedding in lime mortar; and the building of new brick buttresses to further support the repaired walling.
