    Technology

    Teretek®

    Our Teretek® technology provides a solution to address subsided structures, improve ground, and fill voids.

    Re-levelling: Efficient with Teretek®

    Using our specialised expanding resins, Teretek® is a reliable method to lift and level structures.

    With over 30 years of experience in the field, Mainmark’s approach ensures that the structures are lifted without adding weight to the underlying soils.

    Our approach re-levels structure quickly and accurately, allowing for precise adjustments in a controlled manner.

    Ground Improvement: Strengthening Foundations

    Teretek® is used to deliver ground improvement solutions beneath existing structures.

    There are two primary applications for the technology, bearing capacity increase and liquefaction mitigation. Over the past decade, Teretek® for ground improvement has been researched and developed to an extent that it can be designed to a high level of accuracy.

    Throughout its development, Mainmark have worked with international experts on the methodology to test its performance across a wide range of geotechnical conditions.

    Void Filling: Practical and Cost-effective

    Teretek® is well-suited for addressing smaller voids found under concrete slabs.

    By injecting the resin into these voids through small holes, Mainmark reinforces the connection between the ground and the foundation, offering a method that is both quicker and often more economical than traditional excavation and replacement.
