House Underpinning
The art of underpinning structures is as old as that of building itself, going back to ancient times. The purpose of this is to increase the size or depth of a structure’s foundation. This is called remedial underpinning. It is a specialised form of construction and needs to be performed by experienced foundation specialists and engineers.
A solid foundation is the backbone of any home. If your foundation has suffered wear and tear over the years, our underpinning service provides a golden opportunity to address these issues comprehensively. We’ll meticulously stabilize, repair, or reinforce your foundation during the underpinning process, guaranteeing the long-term structural integrity of your home.
Underpinning is a process used to stabilise the ground beneath the property by distributing the load across a greater area. Underpinning is carried out where there are serious problems with movement with the soil.
There are many methods of underpinning a property but the most common is placing friction type piles under the foundation wall. Holes are drilled beneath the existing footings of the external walls to a depth, width and spacing that has been determined by an engineer. The footing and top structure is hydraulically jacked up to level, at this point spiral reinforced steel piles cages are installed into the holes, the engineered spiral reinforced steel cages are then filled with concrete. This method is not suitable for all properties.
