Salted - JP Concrete’s precast service solution for Cornwall’s Walls
6 March 2018
A major upgrade and expansion by JP Concrete of the retaining walls for Scorrier Salt Barn in Redruth will help keep Cornwall’s roads moving during winter time, with over 7,000 tonnes of gritting material securely stored at the depot, the largest in the county.
Working closely with the South West’s main highways, engineering and construction specialist, Cormac (owned by Cornwall Council), JP Concrete provided a complete one-stop, precast service solution, including management of the existing 108m (failing) concrete perimeter and 39m of dividing T-walls that had to be removed and crushed. Damaged over the years by vehicle impact that had caused cracks to appear, the very aggressive salt and brine environment had resulted in severe corrosion and structural uncertainty.
Also managing multiple trades to ensure minimal disruption to Cormac’s operational depot whilst construction work was in progress, JP Concrete supplied and installed bolt-down precast retaining wall units, as well as sealing the floor precast unit joints and vertical joints between units.
Once the existing walls were removed, the new retaining wall units (comprising 103 2.5m L-Units) were positioned, levelled and sealed to provide a clean and effective new retaining wall around the perimeter of the 29m wide x 37m long steel frame building.
The toes of the new units were reversed, so that the loading is on the back. This prevents machines from damaging the toes when loading and unloading the grit-salt. This design layout also protects the fixing in the units from salt corrosion and provides personnel with a safe walkway around the building for easy cleaning and maintenance.
David Vincent, Area Highway Manager for Cormac Solutions, commented: “We needed a company who could provide a complete solution to speedily supply, transport and install new concrete panels, as well as remove and dispose of the old material. We made JP Concrete aware of the critical timeframe for a major delivery of salt, and true to their word, they pulled everything out of the bag”.
He added: “This has been an outstanding collaborative effort. We had to clear space for the work by reducing salt levels, leaving only a tight window of less than two weeks for JP Concrete to get in and carry out their work. We worked closely together on having the old material removed, crushed and recycled, which completed an excellent job all round”.
Prior to the installation at Redruth, JP Concrete worked with Morgan Sindall and Toro Shelters to create a new 5,000 tonne salt barn for Central Bedfordshire Council.
