Access for investigation
The Challenge Geotechnical investigations require drilling in locations specifically characterised by poor ground conditions — the very terrain that makes equipment access and platform stability most difficult.
The Solution Composite mat platforms and access roads enable drill rigs to reach any investigation location safely, without compromising the sensitive ground being studied.
Drill rigs require level, load-rated access in locations often characterised by poor natural ground.
Drilling near waterways or sensitive soils risks contamination from spoil and drilling fluids.
Mobilising drill rigs to difficult ground without proper access adds significant programme risk.
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 works with geotechnical engineers to plan access routes that minimise the total mat footprint while reaching all required borehole positions. This optimises mat quantities and reduces vegetation impact in sensitive investigation areas.
Drill spoil and water from washing equipment must be managed away from the mat footprint to prevent surface contamination. JWA recommends spoil containment bunding integrated with the mat platform on all environmentally sensitive sites.
Real-world examples of how composite matting solves access challenges for geotechnical drilling projects.
The Wheatstone project required geotechnical drilling operations over a period of 12 months. Dura-Base mats were essential for providing access to the site, as the soft ground conditions caused standard all-terrain vehicles to bog. Additionally, the mats protected heavy machinery from the corrosive acid sulphate soils present on site.

The Australia Pacific LNG Project faced 14 months of geotechnical investigations in extremely sloppy ground conditions with daily tidal fluctuations. Dura-Base mats created a firm platform for drilling rigs, enabling over 100 core penetration tests.
