The Screw Piles London project was this residential property had its front area and lower ground floor sink due to subsidence which occurred as a result of the trees located on the public footpath in front of it.
In these instances, subsidence occurs due to the trees which absorb moisture from the soil.
In order to repair the problem, we had to remove the steps going down to each side of the property and excavate along the front as a means to reach down low enough to where was needed.
We then proceeded to install screw piles into the ground which were placed down to approximately 8 metres in depth – the depth at which we encountered firm sub strength.
The screw piles were then connected to the existing property foundations with special bracketry.
In between the screw piles, we cast a ground beam.
In the same vein, we cast reinforced concrete in between the screw piles which spread the load and strengthened the work even further.
