How Do You Fix Subsidence Cracks?

Subsidence, a common structural concern for many homeowners, often reveals itself through unsettling cracks. Left unattended, these cracks can escalate into severe issues jeopardising the integrity of the entire property. Luckily modern technology means that the causes of these cracks caused by subsidence can be fixed much more quickly, with less disruption and at a lower cost than traditional unpinning. By delving into the causes, implementing preventive measures and embracing advanced solutions, homeowners can fortify their structures against the threat of subsidence.

Should I Worry About Cracks In My Walls?

Identifying the Cause of Cracks in Walls

Effective subsidence repair begins with a thorough identification of the root cause. Consulting with an engineer is crucial, as they can analyse the soil composition, assess groundwater levels, and determine if geological factors are contributing to the subsidence. This initial investigation forms the foundation for a tailored and effective repair strategy.

Addressing Moisture Issues

Moisture management is vital in subsidence prevention. Beyond evaluating the property’s drainage system, homeowners should consider additional strategies. Installing gutter systems, grading the land to encourage proper water runoff and employing soil moisture barriers collectively contribute to minimising the risk of recurring subsidence. Effective moisture control complements soil stabilisation efforts and is essential for the long-term strength and integrity of the structure.

Stabilising the Soil

Soil stabilisation is pivotal in preventing future subsidence. While traditional methods like underpinning have proven effective, resin injection is gaining prominence as a modern and efficient technique. This process involves injecting a high-strength, expanding resin into the ground. The resin fills voids and compactifies the soil, providing enhanced support and reducing the potential for future settlement. Its adaptability makes resin injection particularly effective in various soil types and challenging geological conditions.

Addressing the foundation is a critical aspect of subsidence restoration. While underpinning remains a conventional practice, resin injection offers a contemporary alternative for subsidence repair.  The injected resin stabilises the soil beneath the foundation, creating a solid and uniform substrate. This not only supports the structure but also enhances durability and longevity compared to traditional methods.

Crack Repair with Resin Injection

Resin injection plays a pivotal role in crack repair, offering distinct advantages. Beyond filling and sealing cracks, the injected resin binds surrounding soil particles, creating a robust barrier against water infiltration. This dual-action approach not only restores the structural integrity of the affected area but also minimises the risk of further deterioration. Resin injection’s versatility makes it particularly effective in addressing intricate crack patterns and preventing the recurrence of subsidence-related damage.

Monitoring and Preventing Recurrence

Post-repair vigilance is crucial for assessing the long-term effectiveness of the chosen techniques. This is especially true for areas treated with resin injection, as it allows homeowners to gauge the stability and performance of the repaired sections. Continued preventive measures, such as maintaining proper drainage, managing moisture levels and periodic professional inspections are paramount to preventing subsidence recurrence.

Repairing Cracks Caused by Subsidence

Repairing internal cracks requires a systematic approach to ensure a lasting and visually appealing result. Begin by assessing the extent of the damage and identifying the type of crack. Small, hairline cracks can often be addressed with a high-quality interior caulk or filler. For larger or more severe cracks, consider using a flexible patching compound specifically designed for interior surfaces. Before applying any material, it’s crucial to clean the crack thoroughly, removing any loose debris or old filler. Use a putty knife or scraper to create a smooth surface for the repair material. Once cleaned, apply the chosen filler or patching compound, following the manufacturer’s instructions. Sand the repaired area once it’s dry to achieve a seamless finish.

Resin Injection For Subsidence Cracks

If you’ve noticed cracks in your walls they could be a sign of significant subsidence. It’s vital you act fast and if needed, get it repaired. The cracks are just a sign of things to come and the structural integrity of your home could be at risk.
