Basement underpinning is the process of excavating an existing basement to increase its size and also enhance the foundation of a building. Underpinning is done by digging the floor of the existing basement. Once the desired additional depth is attained, the next step involves adding concrete footers, piers, and walls. Depending on the quality of a home’s foundation, you might need to use screw piles and brackets. You can also underpin your basement by installing piles and beams on each side of the basement’s walls.

Basement underpinning offers you an opportunity to add some extra indulgences, such as large windows that transform what’s often a dull space filled with standard furnaces, washing machines, and water heaters. Underpinning requires the input of experts. Without the requisite expertise, basement underpinning can go wrong, resulting in a weak foundation that can lead to structural collapse.

Does Your Home Need One?

Basement underpinning can be done for a variety of reasons. We’ll now walk you through some of the pros of this process. This way, you can determine whether your home currently needs it.

Basement underpinning provides the following benefits:

  • Makes Your Home More Accessible

In most homes, plumbing, wiring, and heating systems are found in the basement. Imagine that you need repairs or general maintenance done on any of these systems. Is the crawling area sufficient for you or a serviceman to carry out the job comfortably? Underpinning allows better access during repairs, upgrades, and inspections. Consider basement underpinning to prevent a situation where you can’t carry out emergency repairs, such as fixing a faulty heating system during winter.

  • Creates Additional Space

Do you need extra space, like an extra bedroom or storeroom? Basement underpinning is the perfect solution when you need additional space but feel constrained by your small plot. You can have your basement excavated to suit your increased demand for this extra room.

You can have the underpinning company create high ceilings to allow for more air circulation and avoid the stuffy feel that’s common with tiny basements. In addition, the team can work on the general lighting so that your basement looks like it has natural lighting. More space allows your family and friends to enjoy comfort when they visit you. You can also convert the additional space into an entertainment room for your family or a home office if you work from home. And if you need extra income, you can convert the extra space into a small apartment for rent.

  • Reinforces Your Building

Adverse weather conditions, unqualified contractors, and soil types play a big role in your foundation’s stability. Significant weaknesses in these factors can compromise the structural integrity of your home, often evidenced by cracks that should be a reason for worry.

Basement underpinning allows you to strengthen your foundation and guarantee your structure’s safety. In addition, the process can improve the stability of your building and increase its lifespan.

Areas with clay soil are prone to land spillage that can shift the ground. This increases the risk of your building collapsing during extreme weather conditions, like flooding. If your home is built in an area likely to experience subsidence or land spillage, basement underpinning will reinforce your home’s foundation.

  • Increases Your Home’s Economic Value

Every homeowner hopes that their property’s commercial value appreciates. Basement underpinning allows you to create additional space-square footage that influences property value affordably. In addition, expanding your basement also allows you to modernize your home, especially if it’s an older style. Modern fittings and style also add to your home’s economic value.

  • Allows The Construction Of Additional Floors

It’s advisable to consider your building’s foundation whenever you want to add additional floors. Ordinarily, your building’s current foundation can only carry the structure’s weight in the original construction plan. When the time comes for structural changes, basement underpinning allows you to enhance your building’s foundation. This enables it to carry additional floors and dead weight from additional fittings and fixtures.

  • Makes You A Recipient Of County Incentives

The heavy downpour experienced yearly in most cities overwhelms the city’s drainage system, causing flooding in the basements of many homes. Basement flooding poses a significant risk to communities living in flooded properties. Some cities offer incentives and rebates for property owners that work with licensed contractors to underpin their basements.


Basement underpinning is a complex process, and a simple mistake can lead to structural collapse. Therefore, various factors must be considered, including soil conditions and building use, when preparing to excavate a basement. This process requires the input of professionals to ensure it is done right.

If your home needs to undergo basement underpinning, consider engaging qualified and insured professionals like aquamasterplumbing with a reputation for excellent home renovations.
