Richard Jackson Ltd were retained by insurers to investigate, design and oversee slope stabilisation works and the re-building of a retaining wall following catastrophic collapse of an existing wall in South London.
The existing retaining wall failed during the night following heavy rainfall. Matters were further complicated by the adjoining property having been extended so that foundations were in very close proximity to the top of slope / retaining structure. A system of soil nails were utilised to stabilise the slope before removing the collapsed wall.
The re-building of the retaining wall further incorporated the soil nailing to ensure its stability. Doing so removed the need for extensive excavations that could have caused further instability both of the slope and consequently above the property above.
All the works were carried out within an area having very limited success and without the need for the occupants to relocate.
