Powerful handheld, reduced vibration, drilling equipment is being used by Roger Bullivant to create a 300mm by 300mm pocket in the side of a property being underpinned in Worcestershire. Subsidence affecting the three-bedroom house in Redditch will be corrected using 18 reinforced concrete needles, cantilevered from 27 piles installed to a depth of 8m beside one wall of the property. Pairs of needle beams will be supported from groups of three piles; with two alongside the house working in compression and a rear pile working in tension.

The contract is being carried out over a period of 15 days on behalf of insurer Royal & Sun Alliance and is set to be completed at the end of May.
