Lower Kelly Landslip


CORMAC Solutions Ltd / Cornwall County Council


Lower Kelly, Calstock



A section of elevated highway collapsed, cutting off vehicular access to homes and trapping 40 vehicles. A piled solution was developed by Cormac Solutions and was installed using one of our Comacchio MC600 drilling rigs. The trapped vehicles were later evacuated by the Royal Navy using one of their Devonport-based landing craft.

Quantum’s solution involved drilling of 47 190mm diameter welded steel cased piles with a 168.3mm diameter thick walled CHS installed and grouted 2.5m into bedrock.  Ancillary Support included on site fabrication and fixing of permanent waling beams.
