The specification of work included installation of masonry Brutt Beams at low level, first floor level and above the first floor window. Intermediate crack stitches were also included.

Small pockets are cut out of the pavement and the toe of the existing foundation is broken off to enable the Heli Piles to be driven as close as possible to the building.

Heli Piles were driven to a depth of 4M using a pneumatic post driver. Once the piles have been driven to the design depth, which is determined by the soil investigation report, tensile proof tests are carried out.

The Heli Piles were linked to the structure with 10mm Brutt Bar loops which are grouted into the side of the foundation or brickwork.

Concrete pile caps are formed to grade C30 to encapsulate the top of the Heli Pile. The tarmac pavement is reinstated.

Once the structure has been stabilised, fractured bricks are cut out and replaced with new.
Gable elevation of a disused commercial unit in Gateshead. Monitoring had taken place across a number of months and it was clear that the right hand side of the building had settled resulting in the fracturing to the gable. The cause of the settlement was attributed to clay shrinkage due to neighbouring trees.
A fast, clean and non-intrusive solution was sought by the client. The repairs were
undertaken using the Heli Pile and masonry beam system and installation was carried out by two operatives, taking five days to complete.
