Geomarine are close to completing a challenging piece of lateral support work for a new basement in Guernsey. The design is a clever use of space to enable a once-closed basement to be flooded with light and have clear access to the outdoors. However a tight site with restricted access and piling in very close proximity to old boundary walls has required Jon Greenfield and his team to implement some novel solutions to form the basement box before it is handed over to the building contractor for completion.
