Poolview and Commercial and Specialised Diving sent us these pictures from one of their jobs at Ponds Forge international Sports Centre in Sheffield, England.
Which is an Olympic-sized swimming pool with 2,600 seating capacity.
The highly skilled work was performed underwater which eliminated the need for draining the huge 2,500,000 litres of water. This avoids the very high costs and any potential damage associated with draining the pool.
Poolview are the UK's leading manufacturer, supplier and installer of Lifeguards "Intelligent Submersion Detection & Drowning Prevention Technology" which was installed on this job in Sheffield.
