The fast & non-disruptive solution to port and seawall subsidence

Mainmark has been providing fast, non-disruptive & cost effective solutions to remediate subsidence beneath seawalls and port terminals.

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.

  • The filling of voids due to erosions because of wave action
  • The raising and re-levelling of slabs in the container yard to ensure smooth travel of straddle cranes
