Over the life of a residential home in Australia, cracks might appear along walls or in the brickwork.

The size or width of these cracks usually indicates the severity of the underlying issue. Common causes of such cracks include poorly compacted backfill, structural inadequacy, or soil settlement beneath the foundation.

To accurately diagnose the cause of these cracks, it’s essential to engage the services of an engineer. This professional will inspect the cracks and conduct soil tests to assess your options.

In Victoria, New South Wales, and Queensland, each region’s distinct soil conditions necessitate specific compaction testing techniques. Victoria’s diverse soil ranges from clay-heavy areas around Melbourne to sandy loam near its coasts. New South Wales, particularly Sydney, is known for its predominantly sandy and clay soils. Queensland, with its tropical and subtropical climate, presents a mix of both sandy and clay soils, with a higher prevalence of expansive clay soils in regions like Brisbane.

If the tests reveal insufficient soil compaction beneath the foundations, the engineer may recommend remedial underpinning measures to prevent further settlement and cracking.

One such effective underpinning technique is Micro-fine cement grout Injection. This method involves injecting a blend of micro-fine cement and water into the soil through a long, hollow injection spear. The grout mixture then infiltrates the soil and solidifies, essentially cementing the soil mass together. This increases the soil’s load-bearing capacity and helps transfer foundation loads to a more stable soil stratum.

Our engineers have extensive experience in the design of micro-fine cement grout injection. Their expertise ensures that all underpinning works are designed to the highest standards, aiming to minimise the potential for further foundation settlement.

If you’ve noticed a crack in your brickwork, it’s crucial to address it promptly to prevent potential structural issues. Don’t wait for the problem to worsen.
