What is underpinning?
Underpinning is a process which strengthens the foundations underneath a house to allow for additional loads or to correct subsidence.
Most of the time, the underpinning of a home is a massive undertaking for everyone involved and can be costly for homeowners. Because of this, it’s particularly important homeowner’s understand what’s causing their home to subside as well as the various underpinning methods available on the market. Homeowners also need to understand the advantages and disadvantages they can bring.
Why underpinning is essential for a sinking home
When a home suffers from subsidence, an immense amount of force is being exerted onto the structure. This force strains the foundations, floor, walls, ceiling and even the roof.
If sinking isn’t stopped, foundational and structural issues like wall cracks can multiply, escalating repair costs to put a large hole in your budget. Underpinning is essential to stopping a home from sinking further, enduring more damage and saving you money.
The most common underpinning solutions on the market
Mass concrete underpinning
Mass concrete underpinning is one of the most commonly known type of underpinning, and is also known as traditional underpinning. It involves excavation of large holes underneath a home and constructing box shaped piers to support your home’s structure. It’s most useful for exposed footings or when floor levels are being lowered to accommodate a new room.
Steel pile underpinning
Steel pile underpinning is an option for homes built on reclaimed land, flood prone areas or land that used to be bogs. The steel piles are driven deep into the ground by specially adapted, tracked excavators. They are then fixed with brackets that are attached to your home’s structure as these types of land tend to be unstable, especially after heavy rainstorms.
Cement grout underpinning
Cement grout underpinning is a form of preventative maintenance for subsiding buildings and structures. Underpinning can be achieved by pumping a special concrete mix or a non-shrink cement grout under structures to fill in large holes and voids. This underpinning method works well if the gaps below a building or structure are large and locatable.
