Huge struts used to prop London excavation

Four 150-tonne working load capacity Groundforce MP150 struts brace the sheet pile and secant pile retaining walls for a basement excavation in West London

Groundforce supplied ten hydraulic struts to support the excavation at a commercial development known as Merchant Square in West London. Six of the struts were the monsters pictured, 500 tonne (1,100 kip) capacity, 49 m (160 feet) long, the largest struts that Groundforce makes. These struts were able to span the entire width of the excavation without intermediate support. Check out the cool time-lapse video below to see the entire sequence of excavation.
