Following clay shrinkage subsidence of a majestic wine store in Milton Keynes in 2018, Optera were engaged by insurers to stabilise and rectify distortions in the brick clad portal frame.
The external column which supports masonry over a flying freehold had dropped which led to cracks in the high level brickwork and bed joints to open in the region of 40mm.
Optera designed and installed a series of 300mm diameter open bored auger piles around the supporting pad footing and jacked the column back to its pre-loss geometry. The resultant lift has closed all but minor bed joint opening which can be locally repaired.
The works were undertaken within 1 week and have been completed ahead of time and within budget.
