WHEN IS UNDERPINNING REQUIRED?
Underpinning is needed if you see any shift of shape on the walls of the building that the walls are beginning to bulge or crack. Another aspect that provides a warning about the failing base is the faults that appear in the arrangement of the house and building doors and windows. On the floor of the house or tower, cracks can also form. The push pier method is the unique device usually debated with this homeowner. When a home settles or cracks, soil movement under the foundation causes it. To combat this problem, engineers developed systems that move the home’s weight off the unstable soil to stable bedrock support. This is achieved by moving down the ground hydraulically galvanised steel piers until they touch bedrock. The home’s weight is then transferred to the piers through the use of rough steel brackets mounted to the home base. It is possible to adjust each pier bracket and pier combination to make the whole home level. The pier structure of the base is secured against the motion and returns the house to a living, stable state.

UNDERPINNING FOR LORD RAMIE RANGERS CEO OF SUN MARK LTD WINNER OF THE QUEENS AWARDS.
Underpinning was dug down 1 meter below existing foundations. Existing foundations were 600 to 800, and 600 underneath the existing footings.
Once we dug down undersides to be cleaned of all soil.
H16 dowel bars were put in, connecting all the underpinning together.
Once this was then inspected by building control, and passed, pins were then shuttered up and a 75mm gap left under existing footing.
Concrete was poured and dry packed 24 hours after.
All pins were carried out in one metre sections. As per sequence in the drawing.
Muck dug up from the work area was put back in and compacted down every 300.
Remaining muck was taken to the front of the property and removed from site via grab lorries.
Pins were dug out using a mini digger, and hand dug in places where the digger could not reach, muck was carried to the front using a one ton dumper.
All muck was then removed from the site using grabs.
