Cost-Effective Infrastructure Repair

Extending the Lifespan of Utilities through Proven Ground Engineering Techniques

Repairing ageing and damaged infrastructure is most often more cost effective than replacing it.

Mainmark uses proven ground engineering and asset rehabilitation solutions and techniques to help asset owners including local councils to extend the life of utilities.

Our expertise extends to remediating assets for electricity, gas, waste management, telecommunication providers, as well as water authorities.

De-commissioning Assets

Utilising non-invasive solutions

When preparing to decommission or abandon below-ground assets, our Terefil® technology provides an advanced lightweight cellular concrete for soil replacement, large void filling, and pipe abandonment.

Teretek® improves ground beneath assets and corrects subsidence, minimising downtime and service disruption.

Our non-invasive solutions eliminate the requirement for excavation, ensuring minimal disruption to the surrounding area.

  • Correcting tilted transformer slabs
  • Mitigating risk of rocking of wind turbine base pads
  • Lifting out dips where water is ponding
  • To provide targeted ground improvement to weak sub-grade soils
