Penzance’s Jubilee Pool lido is undergoing stabilisation work to safeguard the Grade II-listed seafront structure following storm damage during winter 2014.
Geotechnical contractor Saxton Drilling is working with Cormac Solutions to anchor the base of the tidal pool to the underlying bedrock.
According to owner Cornwall County Council, the base of the 1930s Art Deco pool was replaced in 1997 but the depth to bedrock below the structure varies from 2m to 6m. The pool lies within the tidal range so can only be used at low tide and is drained and refilled every two weeks.
A spokesperson for the council said: “There is evidence that the pool base flexes due to hydrostatic pressures with the movement of the tides and is causing cracking of the pool base, consequently the pool cannot be left empty when the tide rises because of the risk of damage to the pool base.”
Saxton is installing 95 33mm diameter rock anchors into 3m long rock sockets to secure the pool base to the underlying bedrock. Anchor plates will be covered and joined by a 150mm structural concrete slab at the end of the work.
The Coastal Communities Fund granted the council £1.95M to partly fund the £2.9M scheme that will also see other facilities at the pool upgraded. Match funding has also been provided the council, Cornwall and Isles of Scilly Local Enterprise Partnership’s Regional Growth Fund, Tempus Leisure, the Friends of Jubilee Pool, and Penzance Town Council.
The pool is scheduled to reopen in spring 2016.
