Ground Improvement


Pioneering ground solutions for modern construction

As urbanisation and population growth surge, so does the need for engineered ground improvement solutions.

The escalating construction and retrofit of buildings and infrastructure highlight the importance of foundation performance, increasing longevity and safety.

Mainmark specialises in advanced ground improvement methods. Ground improvement modifies a soil’s properties, improving its load bearing capacity or resilience against liquefaction. Mainmark specialise in delivering a suite of technologies that cover densification, solidification, and soil replacement methods.

We use our Teretek® resin injection technology to enhance soil properties beneath existing structures. In areas with challenging ground conditions, we use Terefil® to replace the existing soil with an engineered lightweight, cellular concrete raft. Our permeation grouting and jet grouting techniques solidify soil, increasing load bearing capacity.
