A-frames not required below ground in Central London by using the recostal® system
Project: Basement with single-sided retaining wall
Location: Hanover Square, Central London
Contractor: J Coffey Construction
Developer: BJV Retail Developments
Product used: recostal® 2000GT
A challenging project in the middle of London, surrounded by other buildings in close proximity. The basement under construction required a single-sided retaining wall.
By using recostal® 2000GT as an ‘internal shutter’, the contractor avoided the use of conventional A-frames, thereby obviating any party wall complications – no loads were transferred to the surrounding party walls.
Inform UK provided on-site technical support as well as initial design drawings. recostal® 2000GT achieved faster controlled pours, allowing the hydrostatic pressure to come back in to the structure. The package supplied by Inform UK included a water coupler system allowing connection between the internal recostal® sheet and external shuttering. Water ingress along the tie rod was thus prevented. In addition wall thicknesses were controlled and the site footprint maximised.
The project manager, Mr K. Kalapan said “the benefit of controlled pours rather than a conventional single sided solution, plus not needing to utilise ‘party walls’ in the process was very helpful.”
