    Ground Strengthening for Properties

    When the ground beneath a property begins to show signs of instability, it’s time to consider ground strengthening solutions.

    Our innovative solutions address issues like subsidence, safeguarding the safety, stability and operational continuity.

    Mainmark offers quick, non-disruptive, and cost-effective ground-strengthening solutions as experts in ground improvement technologies.

    Our solutions:

    • Improve the soil’s load-bearing capacity and provide resilience against liquefaction
    • Fill voids in the soil under foundations, improving stability and supporting foundations
    • Lift structures, gently and accurately returning them to level

    Ground Strengthening

    Non-invasive Solutions

    Our Teretek® resin injection, JOG computer-controlled grouting and Terefil® lightweight cementitious fill methods provide non-invasive alternatives to traditional ground improvement techniques and require no extensive digging or excavation.

    They are suitable for all types of commercial and residential buildings, from factories and  to public buildings and social housing, as well as car parks, roads and bridges.

    Work can typically be completed from within a a few hours to a matter of days, depending on the complexity of the project and the size of the building.

    There is no need to vacate the property while our ground-strengthening solutions are being implemented, and the treated area returns to full operation immediately after the repairs are carried out.

    Ground Improvement

    Why is Ground Improvement required?

    Ground improvement is a solution for subsidence, which can cause buildings to sink or lean, walls to crack and floors to become uneven

    Subsidence can be caused by various natural and human-induced factors, including:

    • Drought or prolonged dry spells – During these periods, soil loses moisture and shrinks, leaving voids under the foundations.
    • Overgrowth of trees and shrubs – These can absorb moisture and dry out soil.
    • Soil erosion – This can be caused by heavy rainfall, flooding, damaged drains or broken pipes.
    • Soil decomposition – Soils with high organic content can decompose over time. This releases gases like carbon dioxide and methane and creates voids in the soil.
    • Nearby heavy traffic – Over time, the underground vibrations caused by heavy traffic can lead to soil compaction.
    • Historic mining activities – The removal of minerals or ores can leave underground voids that can cause the overlying rock and soil to collapse.

    If signs of ground weakness, instability or subsidence are observed, quick action is necessary to prevent further damage. Mainmark’s ground strengthening solutions can address these problems, helping to keep your commercial property stable and secure.

    Ground Strengthening FAQs
    What are the methods of ground strengthening?

    Typical ground strengthening techniques include soil replacement, compaction grouting, jet grouting, and a variety of ground improvement methodologies including geopolymer resin injection. Ground strengthening is a crucial process for enhancing the bearing capacity and stability of soil to support structures.

    Teretek® Engineered Resin Injection: This is Mainmark’s proprietary solution, a two-part resin that is injected into the ground. It expands, fills voids, and compacts loose soil, significantly increasing its bearing capacity. This method is ideal for residential, commercial, infrastructure and mining sectors as it is quick, clean, and minimally invasive, causing little to no disruption to the property.

    This method is tailored to meet the specific needs of a project, ensuring that ground conditions are adequately addressed. Mainmark’s expertise lies in evaluating the site conditions and recommending the most appropriate ground strengthening method to ensure long-term stability and safety.

    What is meant by ground strengthening?

    Ground strengthening refers to enhancing the load-bearing capacity and stability of the ground, often carried out before the construction phase to better support structures and infrastructure.

    Mainmark excels in this field by offering cutting-edge, non-invasive solutions like their Teretek® engineered resin injection, which significantly enhances ground conditions without the need for excavation or heavy machinery. This innovative approach ensures a solid foundation for any construction or repair work, providing peace of mind and long-term reliability for property owners and managers.
