10 years after HeliBeam system repairs, moving property still retains stability

Client:	Royal Insurance Engineer: Lloyd Associates
Location:	Glastonbury
Reference No:	CS013

Property, built on the side of a steep hill of clay overlaying rock, was suffering from masonry cracking due to widespread ground movement.
Main building, on stepped footings, was separating from rear extension built on a concrete slab.
Front corner of the building had fallen away due to subsidence, caused by an adjacent tree, and vertical cracks were running from the upper windows to the DPC.

No practical options were available as piling or mass underpinning were likely to disturb the footings and accelerate movement.

Our Approved Installer used the Helibeam System in one of its first insurance-backed repair programmes.
Pairs of stress-free stainless steel HeliBars were grouted into five selected mortar beds around all sides of the building to create deep masonry beams: two above the DPC, two under the upper storey windows, one under the eaves, with grouted CemTies installed on the internal corner.
The whole structure was reinforced and loads were redistributed allowing the masonry to bridge over areas of subsidence.
Individual cracks were stitched with concealed grouted HeliBars.

The only repair accepted by the Royal Insurance.
Differential movement was arrested, integrity was reinstated, future cracking and small cyclical movements prevented and all repairs were hidden.
The property regained insurable status, was mortageable and was sold.
10 years after repairs, no further problems have occured.
