Basement underpinning
Underpinning is a process used to strengthen the foundation of buildings. It may be necessary when:
- The usage of a building has changed (when there is an extra strain on the foundation because of the house extension).
- The existing foundation isn’t strong enough and cannot support the structure (when the type of soil was misclassified at the design and development phase).
- The soil supporting the foundation of the main building has changed due to subsidence or as a result of some natural disasters.
- The owner wants to increase the height of the ceiling in the basement.

How Can A Basement Floor Be Lowered?
Do you consider expanding your home down but not sure if it’s possible? The short answer is yes. In fact, many families choose basement lowering as the most convenient way of adding more space to your home. It’s a great way to increase the size of your property without sacrificing the backyard zone and without having to build an extra floor.
In many buildings, basements used to have limited functionality. They were intended as a structural part of the house, the sole purpose of which was to provide access to apparatuses. In order to add extra space in the basement, you need to make changes to the foundation wall. It’s not easy but it’s definitely possible. There are several ways of having your basement floor lowered. All of them require structural changes and the ultimate choice depends on your vision and your budget. Foundation underpinning is one of the most popular methods up to date.
















What Is Foundation Underpinning?
Underpinning Stages
Underpinning is a complex process that involves multiple stages. Here’s how a typical process looks like:
- Property examination and planning
- Digging a series of holes below the foundation footing
- Filling them in sequence to strengthen and lower the footing
- Digging out the soil left on the inside of the foundation
- Finishing up the renovation
It’s extremely important to entrust it to highly qualified experts with professional knowledge of excavation, building foundation walls, footings, doing concrete work, plumbing, and more.
Remember that underpinning is a complex process that takes a lot of time and requires a certain budget. However, if done right, it can have a tremendous result – a living space you’ve always dreamed of, be it extra space for your teenage kids, an office, gym, storage, entertainment space, a separate room for rent, and anything else you can imagine.
