At MAA Corp, earthworks are at the core of what we do. With extensive experience in Transport for NSW (TfNSW) and local LGA specifications, including R44 Earthworks, we deliver solutions that meet the highest industry standards. We understand the critical role that quality, precision, and compliance play in ensuring the success of every project. 

Our Approach to Earthworks

Our process is guided by key principles that reflect our commitment to quality and conformance: 

       Material Quality and Suitability

We source and use only the highest quality materials that meet stringent engineering specifications, including grading, plasticity, and moisture content. Each material undergoes thorough testing to confirm compliance before placement.

        Relative Compaction

Achieving optimal compaction is non-negotiable. Our team ensures every layer meets the required compaction levels, verified through rigorous testing which include relative compaction, proof rolls and Benkelman beam testing to guarantee stability and durability.

        Moisture Content Control

Materials are moisture-conditioned to meet the specified range, ensuring proper compaction and avoiding issues like cracking or shrinkage over time.

         Layer Thickness and Uniformity

Fill is placed in carefully measured layers, typically 200–300mm compacted thickness, and compacted evenly across the site. This systematic approach prevents variability and ensures structural integrity.

         Inspection, Testing, and Documentation

Our in-house Inspection and Test Plans (ITPs) provide clear guidance at every stage. All tasks are inspected, monitored, and documented to ensure compliance with R44 specifications. This meticulous process minimises risks and ensures long-lasting results.

Engineering Support

Our engineering team works closely with site crews to provide real-time technical guidance, address challenges, and ensure every task is executed efficiently and to the highest standards. This collaboration ensures a seamless process, even on the most complex projects.
