Soil Testing

Know where you stand with ASCT and our industry leading soil testing. Our soil testing services are part of a larger suite of geotechnical investigation used to determine the characteristics of a site’s foundations. Soil testing measures a variety of both physical and chemical properties ensuring you have a reliable overview of what lies underneath your building site. Our soil testing services are performed on samples sourced from various depths to provide an accurate and comprehensive soil analysis.

Australian Soil & Concrete Testing conducting Construction Materials Testing and Soil Testing with NATA accreditation

SOIL SPECIALTY TESTING

NATA-Accredited Soil Testing

All ASCT soil testing is conducted as per the relevant NATA, Australian Standards (AS) and State Government standards.

These tests are important for a number of reasons:

Regulatory compliance: Many local government organisations require soil testing before issuing construction permits, and failure to comply can result in costly delays and fines.

Quality Assurance: Ensuring your soil has the correct composition and properties is key to the long-term structural integrity of your development.

Cost Reduction: Uncovering issues in the initial phases of development provides an opportunity to implement correctional measures to avoid potential delays and additional expenditure.

Safety: Soil composition is key to ensuring your development is stable and not at risk of a collapse or failure.

ASCT works with your project partners to mitigate issues and provide solutions to soil testing issues you face ensuring you meet your project deadlines. Bringing certainty to the construction industry for over 30 years, ASCT have an extensive track record of success with projects of all shapes and sizes. From residential renovations to large scale infrastructure projects, ASCT have you covered. Additionally, our fleet of mobile annex laboratories provide the opportunity to service projects in remote locations. As our client, you will know exactly what the site consists of, the suitability and our advice for continuing the project.

Get in touch with ASCT and employ the power of certainty to mitigate project risks during your construction process.
