Innovative Technologies For Rapid Repair

The fast, non-disruptive solution for airport and taxiway subsidence

Across Australia and internationally, Mainmark has been providing fast, non-disruptive & cost effective solutions to remediate subsidence beneath airport assets since 1989.

Our technologies offer distinct benefits in addressing issues like bearing capacity failures, voiding, and loss of support often found in aging infrastructure, all while avoiding the expensive costs and disruption to operations typically associated with sub-grade and pavement removal and replacement.

Mainmark’s solutions and technologies are particularly well suited to address the complex challenges of airport pavement repair, including:

  • The filling of voids directly beneath pavements to reconfirm support and limit deflection and deterioration.
  • Raising subsided pavements to re-establish design levels and/or drainage gradients.
  • To provide targeted ground improvement to weak subgrade soils
