Shoring supplier Groundforce's modular propping system has been used to support a brick retaining wall being underpinned at Hossier Lane in central London.
Construction firm Laing's building subsidiary, Holloway White Allom, is working on a £3.5M,2,000m 2office building for the charity the Haberdashers Company.
The old retaining wall supports a street 3.5m above the original basement level and is founded on fill over Thames Gravel. It is being incorporated into the new deeper basement and substantial temporary support was needed to prevent inward movement and rotation of the brickwork during demolition and excavation.
An 88m long Megabrace waling was fitted against the wall, supported by 16 hydraulic struts bracing off new and existing floor slabs.
