Fast food order delivered

FORTICRETE ENGINEERING Products' Keystone dry build wall system was a quick solution for a major retaining wall at a new food factory at Manton Wood near Worksop in Nottinghamshire.

The 250m long structure was built in only six weeks.

Site topography meant substantial excavation had to be carried out to allow construction of the ground level loading area at the rear of Hazlewood Chilled Foods' new facility. This created a 250m long, 6m high steep embankment alongside the access road to the loading bays.

The Keystone block wall, which locks together using strong pultruded fixing pins, was used to create the retaining wall to the slope. Tensar geogrids were 'locked in' using the pins and extended to a tail length of 3. 5m to the rear of the wall. The wall was backfilled with several hundred tonnes of sandy material excavated from site and 20mm clingstone.

Chester-based PC Construction built the 900m 2wall supervised by main contractor Clegg Food Projects. After the 300mm deep and 600mm wide dry mix concrete foundations were laid, a team of four with an excavator was able to build about 40m 2 to 45m 2of wall a day using the mortar-free system.
