Underpinning is a method we use to strengthen the foundation of an existing building or structure. As underpinning contractors, we use this method for a variety of reasons depending on the circumstances. Underpinning is used for a variety of reasons. It is needed when an original foundation is simply not strong or stable enough, the usage of the structure has changed, the properties of the soil supporting the foundation have changed, or simply to add extra depth to a room or to add a basement.
Underpinning involves extending the foundation so that it rests on a more supportive system. It may be a more cost-effective solution to improve the current foundation of the building than constructing a new one. Our team of underpinning contractors in London, Exeter, Bristol and Birmingham are happy to answer any questions you may have.

What is building Subsidence
Building subsidence damage tends to occur when movement in the ground causes the building foundations to shift. The damage often will show up as cracks in walls or ceilings.
There are a number of reasons for subsidence, but most commonly it’s caused by faulty drains, tree roots sucking the moisture from the soil, or by drought or a change in the level of the water table.
