Understanding Different Types of Foundation Repair Methods

Posted on: 14 August 2023

A good foundation is important for the structural integrity of any building. However, over time, foundations face integrity issues caused by factors such as soil movement, water damage, or poor construction. When foundation problems arise, it's important to address them promptly to prevent further damage. Understanding the different methods of foundation repair will help homeowners make informed decisions when it comes to their foundations.

Foundation Underpinning

Foundation underpinning is a common method used to stabilize and reinforce a foundation that has experienced settlement or is showing signs of sinking. This technique involves installing additional supports under the existing foundation to provide extra strength and stability. The process usually includes excavating sections of the foundation and placing piers or helical piles at strategic points to transfer the weight of the structure to more stable soil layers.


Slabjacking, also known as mudjacking, is a technique used to raise and level sunken concrete slabs, such as basement floors, driveways, or sidewalks. This method involves drilling small holes into a sunken foundation slab where a mixture of cement, sand, and other additives are injected under high pressure. The injected material fills voids and lifts the slab back to its original position, effectively restoring its level and stability.

Carbon Fiber Reinforcement

Carbon fiber reinforcement is a non-intrusive method used to strengthen foundation walls that are experiencing cracking or bowing. Carbon fiber strips, which are lightweight and incredibly strong, are applied to the affected wall using epoxy adhesive. Once installed, the carbon fiber creates a tensile strength that prevents further movement and distributes the load evenly. This method is particularly effective for stabilizing foundation walls and preventing further damage caused by hydrostatic pressure.

French Drains

French drains are an effective solution for managing water accumulation around the foundation, which can cause soil erosion and compromise its stability. A French drain system is a trench that's filled with gravel and connected to a perforated pipe that can redirect excess water away from the foundation. This method helps to control the water table and prevents moisture buildup around the foundation, reducing the risk of foundation damage due to hydrostatic pressure.


Waterproofing is a preventative measure that helps protect foundations from moisture penetration. This method involves applying a waterproof membrane or coating to the exterior walls of the foundation. It creates a barrier that prevents water from seeping into the foundation walls, effectively reducing the risk of water-related damage, such as cracks and deterioration.

Understanding the different types of foundation repair methods is essential for homeowners facing foundation issues. By taking prompt action and choosing the right repair method, homeowners can ensure the long-term stability and integrity of their foundation, protecting their investment and ensuring the safety of their home.
