Load transfer in building a road over mine workings
Geogrid reinforced load transfer platforms have been used in a complex £2.5M access road project for a new housing development near Glasgow, built over redundant mine workings.
Keller Ground Engineering's subcontracting arm, Comtec, secured a design and construction package for bridge approach embankments up to 8m high.
Working with the Tensar design team, Comtec proposed load transfer platforms of Tensar geogrid reinforced fill as being cheaper and quicker than concrete rafts or pile caps.
Time saving in sewer construction for a bypass scheme
Deep drainage specialist Dragtone has been using a new 'rolling strut' trench support system from Groundforce in the installation of sewer pipework 9m down on the Swindon Northern Orbital Road.
The system (pictured right) provides full vertical support of a narrow trench, avoiding the need for wider excavation at the surface and so minimising disruption. As trench excavation proceeds, rails and panels can be pushed further into the ground.
