Infrastructure

Roads, Bridges & Culverts

Keeping Australia’s roads operational with minimal disruption

Keeping transport infrastructure functional

Since 1989 Mainmark has been providing fast, non-disruptive & cost effective solutions to remediate subsidence beneath road surfaces and bridge approaches.

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 road closures typically associated with sub-grade and pavement removal and replacement.

Some of the more common applications for the remediation of roadways are:

  • The filling of voids directly beneath pavements to reconfirm support and limit deflection and deterioration.
  • Raising subsided pavements to re-establish design levels, drainage, or camber gradients to restore a safe and comfortable ride for motorists.
  • Void filling, Re-supporting, and Raising bridge approach and relieving slabs.
  • To provide targeted ground improvement to weak subgrade soils.
