Support for the heaviest loads
The Challenge Heavy lift operations concentrate extreme loads on small areas through crane outriggers and heavy transport vehicles — loads that existing ground and infrastructure cannot absorb without engineered protection.
The Solution JWA composite mat systems distribute extreme point loads from heavy lifts and transport routes, protecting underground assets and preventing ground failure during critical operations.
Crane outriggers and heavy transport impose extreme point loads requiring engineered ground support.
Concentrated loads from heavy lifts cause irreversible sub-surface compaction and localised ground heave.
Ground preparation for heavy lifts adds cost and time — delays to lifts carry major programme impacts.
Deploy rapid access systems that protect the environment while supporting heavy loads.
Engineered composite mats distribute weight effectively, preventing bogging and ground damage.
Quick installation and removal means minimal downtime and maximum productivity.
Our systems provide reliable access in any weather conditions, keeping projects on schedule.
Durable construction allows for multiple deployments, reducing overall project costs.
JWA recommends integrating mat platform design into the lift study process, prior to final lift plan submission. This ensures ground support is specified against the confirmed outrigger load diagram rather than general estimates, and allows time for any additional geotechnical investigation required.
Before specifying mat coverage for abnormal transport routes, a buried services survey is essential. JWA works with project engineers to identify the critical load points along the route and design mat configurations that protect the most vulnerable assets.
Real-world examples of how composite matting solves access challenges for heavy lift projects.
How Dura-Base Composite Mats provided a cost-effective alternative to traditional crushed rock for the 180MW Dulacca Windfarm project, protecting sensitive agricultural land.
Sakhalin Island, Russia
The Sakhalin-2 oil and gas development in Russia required a reliable and portable composite matting system to facilitate the construction of an LNG plant. Dura-Base mats were used to create heavy lift access pads for self-propelled modular transporters (SPMTs) to move massive modules across sandy terrain in extreme weather conditions.

Dura-Base mats were subjected to rigorous tank trials to test their suitability for military use. The mats provided a robust surface capable of withstanding the immense weight and abrasive tracks of heavy military vehicles.
Central Queensland, QLD
The 3,200T Marion 8050 dragline was scheduled to travel for four months through the rugged outback terrain in regional Queensland, Australia. This massive machine relocation required careful planning and robust ground support systems.

The Boeing KC-135E Stratotanker required a robust surfacing solution for taxi aprons and parking during military exercises. Dura-Base mats provided a 105mm thick, interlocking platform capable of withstanding the 135-tonne aircraft loads.
Western Australia
How composite matting was used to support works at a Class A Nature Reserve. This environmentally sensitive project required the highest standards of ground protection.
Undisclosed
Defence armed forces required a temporary camp to conduct training in a remote desert environment characterised by barren, dusty, and sandy terrain. Dura-Base mats were deployed to create a stable 5,000sqm surface for the camp.
India
Dura-Base oilfield mats created a safe work platform for Weatherford’s Rig 807 drilling operations in India. The unique movable rig subbase exerted extreme pressure of over 175,000 lbs per tire, which the Dura-Base composite system handled successfully.
