Substantial traffic and heavy loads put a huge strain on ageing roads and infrastructure at busy port terminals.

This can cause significant ground subsidence, damage to concrete foundations, and infrastructure to deteriorate under pressure.

Left untreated, this can pose safety risks and interfere with the smooth running of port operations. It can render runways unsafe for aircraft and dockyards unusable and destabilise crane rails. Because ports operate around the clock, securing downtime to undertake repairs is challenging and costly. Mainmark’s environmentally-inert solutions are fast and proven, minimising downtime to reduce disruption. In some cases, projects can be completed during normal operations. Our solutions help to make these busy transport hubs safer and more efficient, quickly returning them to normal operation.

We solve problems at Airports

Raise, re-level and repair subsidence beneath airport buildings, concrete slabs, runways and hangar floors using JOG Computer-Controlled Grouting and our Teretek engineered resin solution, often without vacating the premises

Protect and revitalise ageing concrete and steel structures, such as tanks, concrete slabs and walls, using ENCAP6

Strengthen and stabilise ground to prepare for airport construction using Permeation Grouting and Jet Grouting

Fill large voids beneath airport runways, taxiways and airport buildings, decommissioned pipelines and culverts, and abandoned underground structures to increase load bearings using Terefil

Renew concrete runways, roads and driveways using Ultra-Panels

Success story:

Abandoning a concrete pipeline beneath an operational pavement in a busy Airport

On discovering significant damage to a 280 metre concrete pipe located beneath a high load, 24/7 operational pavement, airport engineers appointed Mainmark to fill the voids and permanently abandon the pipeline. We successfully completed the project in two stages over just three separate weekend shutdowns, with limited to access to the pavement areas above the pipe. Resin was injected to fill surrounding voids and protect against water ingress, and then Terefil was used to fill and decommission the pipeline. It delivered a minimum strength of 1,000kPA to withstand the heavy loads in this busy port environment.

We solve problems at Seaports

Raise and re-level docks, warehouses, weirs, shipyards, sea bridges, and roads with JOG Computer-Controlled Grouting and Teretek engineered resin

Repair and revitalise ageing seawalls, piers, wharves, tanks, and concrete walls with ENCAP

Remedy coastal and soil erosion and strengthen ground before seaport construction with Permeation Grouting

Stabilise lose or weak foundation ground with Jet Grouting

Fill voids, decommissioned pipelines and culverts, and abandoned structures beneath seaport infrastructure with Terefil for increased stability

Rehabilitate concrete roads, pads, wharf floors, and sea bridges with Ultra-Panels

Success story:

Restabilising a wharf near the environmentally-sensitive Great Barrier Reef

Erosion beneath a wharf facility in remote Far North Queensland was making it difficult for an important mining site to operate mobile cranes and transport heavy loads. Extreme tidal activity had caused the backfill to erode through the seawall, rendering the wharf unsafe. Proximity to the Great Barrier Reef World Heritage Area demanded an environmentally-sensitive solution to stabilise the seabed and seawall embankment at the shipping port. In just 9 days, Mainmark re-supported the wharf slab using Uretek deep resin injection method, making the wharf safe to bear the typical loadings of 90 tonnes or more.
