Masonry beams and Cemflex ties through the masonry were installed to stabilise the walls.

Areas of the walls where bulging was evident were drilled and the core was injected with Pozzolanic grout as a means of stabilising the core and preventing further settlement.

The original proposal was to take down the pillars to the Gin-Gang to enable mass fill underpinning. However, the pillars to the Gingang were carefully excavated in stages and 60mm diameter Helical Piles were driven to an average depth of 2M.

Reinforced concrete pile caps were cast onto the top of the piles to support the Gin-Gang pillars. Once the concrete was cured, the opposite side was piled and capped.

The walls to the main building were supported by pairs of internal and external Helical Piles at 2M centres.

The Helical Piles were connected with pre-fabricated steel cages and C30 grade concrete was used for the beam.
The restoration of this farm building and Gin-Gang, situated in a rural area of
Northumberland, included the installation of Helical Piles as a method of underpinning to satisfy Building Control.
The original proposal involved traditional underpinning using mass concrete. However, the constraints of a short program and issues with safety, due to deep excavation and the risk of collapsing masonry, meant that the Pile and Beam system were ideal.
The masonry was consolidated by grouting and strengthened by the installation of a
continuous masonry beam and Cemflex ties. The Helical Piles were installed at strategic locations to not only support the main structure, but also carry an internal steel frame which in turn, supported the roof.
