The foundation is a crucial component of any home, bearing the weight of the entire structure. However, it can succumb to issues like settling, shifting, or cracking over time. Here are common types of home foundation repair methods that homeowners can leverage to ensure the structural integrity of their properties.

Piering

Piering is a popular method used to address settling issues in foundations. This method involves driving steel pipe pilings into the ground beneath the foundation until they reach a stable soil layer. Hydraulic jacks then lift the foundation to its original level, and the piers are locked to provide permanent support. 

Piering is further divided into two types: push piers (driven piers) and helical piers. While both serve the same purpose, helical piers, equipped with helical plates to pull them into the soil, are typically used when there's a need to resist both downward and upward force.

Slabjacking

Slabjacking, also known as mudjacking, is a repair method where a mixture of soil, cement, and water (mud) is pumped beneath the foundation. The pressure from this injection raises the foundation back to its original level. 

This method is cost-effective, minimally invasive, and suitable for repairing small to moderate foundation settling issues.

Sealing

If the foundation damage is due to water leaks or moisture penetration, sealing is a commonly employed repair method. Waterproof coatings or sealants are applied to the interior or exterior of the foundation walls, preventing water from entering. 

In more severe cases, a complete waterproofing system, including drains and sump pumps, may be installed.

Underpinning

Underpinning is a method used to strengthen an existing foundation. This process involves excavating sections of the ground below the current foundation and filling these sections with concrete or steel supports. 

Underpinning is typically used when the original foundation is not strong or stable enough to support the home, often due to changes in soil conditions or an additional building level.

Crack Repair

For minor foundation cracks, a simple crack repair may be sufficient. This repair typically involves the use of an epoxy or polyurethane resin injection to fill the crack, preventing further damage and water penetration. 

While this method is relatively straightforward and affordable, it's suitable for small cracks only and does not address potential underlying issues.

Preventive Measures and Maintenance

Beyond repairs, it's crucial for homeowners to focus on preventive measures and regular maintenance to avoid severe foundation issues. This includes addressing soil, drainage, and other issues. Contact a home foundation repair contractor for more information.
