Other building work nearby has caused disruption to your property or neighbouring property causing a shift underground. Sometimes when other buildings have work done, the excavation of those footings close to existing footings can leave the other property exposed. It is important that excavation work next to other buildings is done carefully to prevent the potential need to underpin foundations in the future.
Underpinning foundations traditionally consists of digging a hole under and around the existing foundations and filling squares of concrete beneath to create a stable point base for the original foundations to rest on, preventing further movement.
There are other methods where the above option is not viable, this may involve steel or concrete pins that can be drilled down into the soil until a solid base is found, there can then support the existing foundation by bearing the load further down where the ground is more solid.
If you think that you need underpinning or have been advised that underpinning is necessary for your building then speak to us, we can advise on the best options based on the current structure and condition of your footings, to ensure that you make the right choice in terms of cost and structure for your home
