At some point in your life, you may have heard the term underpinning being thrown around. But what does it really mean? In simple terms, underpinning refers to the process of strengthening the foundation of a building to prevent further damage. Whether it’s due to subsidence or any other reason, if your home’s foundation is not stable, it can lead to severe structural damage. This blog will discuss the basics of underpinning, including its benefits, types, and when it’s necessary to opt for underpinning.

Benefits of Underpinning

If you’re planning to sell your home, underpinning can increase its value by making the foundation stable. Additionally, underpinning reduces the risk of any structural damage, which can help you save money by avoiding costly repairs. It also protects the structural integrity of your home and enhances its lifespan.

Types of Underpinning

There are a few different types of underpinning available, and your choice will depend on factors such as the extent of damage and the nature of the soil. Here are some of the types of underpinning you can consider:

  • Mass Concrete Underpinning: This method involves filling the entire area beneath the building’s foundation with concrete. It’s suitable for smaller buildings and when the soil isn’t too soft.
  • Beam and Base Underpinning: This method involves creating a reinforced concrete beam and base beneath the existing foundation. It’s suitable for most soil types and can be used for larger buildings.
  • Mini-Piled Underpinning: This method involves drilling holes into the soil and inserting piles that are made of steel or concrete. It’s suitable for soft soils and when the building is located in an area with limited access.

When is Underpinning Necessary?

If your home experiences subsidence, it’s important to address it as soon as possible to prevent further damage. Subsidence occurs when the soil beneath the foundation of a building shrinks or shifts, causing the foundation to crack or sink. Other reasons for opting for underpinning include changes in the building’s use, the occurrence of natural disasters, and problems caused by nearby construction work.

Underpinning is a process that’s essential for maintaining the structural integrity of your home. Choosing the right type of underpinning depends on the extent of damage and the nature of the soil. Additionally, it’s important to hire a professional who has experience in underpinning to ensure that the work is done efficiently and effectively. If you suspect any damage to your home’s foundation, don’t hesitate to get it checked out by a professional. Remember, preventative measures can help you save money and protect your home’s value in the long run.
