Foundation Repair Solutions

At Grace Foundation Solutions, we recognise that each foundation issue is unique and requires a tailored approach to ensure effective repair. This section explores the variety of foundation repair solutions we offer, designed to address the diverse problems that may affect homes in New Zealand. From traditional methods like underpinning to modern techniques such as resin injection, we detail how each solution works and its suitability for different foundation conditions.

Types of Foundation Repair Solutions


Underpinning is one of the most common and effective methods for repairing foundations that have shifted or sunk. This method involves extending the foundation in depth or breadth so it rests on more supportive soil. There are different types of underpinning techniques, such as mass concrete underpinning (traditional method) and the more modern micro-piling. The choice of technique depends on the soil type, the extent of damage, and the load of the structure.


Slabjacking, also known as mudjacking, is a repair technique used to lift and stabilise sinking concrete slabs. It involves drilling holes into the affected slab and then pumping a mixture of water, soil, sand, and cement beneath the slab to raise it back to its original level. This method is ideal for repairing smaller slabs such as driveways, walkways, and patios that have experienced minor to moderate sinking.

Resin Injection

Resin injection is a more advanced solution that offers a minimal invasion approach to stabilising and lifting foundations. By injecting a polyurethane resin into the ground beneath the sinking areas, the resin expands and hardens, lifting the foundation back to its proper level and stabilising the soil around it. This method is highly effective for residential areas and is quick, clean, and causes minimal disruption to the property.

Structural Repair and Reinforcement

In cases where the foundation damage is extensive, structural repair and reinforcement may be necessary. This could involve installing new support beams, reinforcing existing beams with steel braces, or using carbon fibre reinforcement to strengthen weakened areas of the foundation. These solutions are customised based on the architectural requirements and the specific needs of the building.

Choosing the Right Repair Method

As discussed in previous sections, the selection of the appropriate repair method depends on a thorough diagnostic assessment. Our team of experts at Grace Foundation Solutions evaluates several factors, including the type of foundation, the severity of the damage, the soil conditions, and the overall structure of the building, to recommend the most effective repair solution.
