Soil Testing & Design

Soil Testing in the Sunshine Coast, Brisbane, & Gold Coast

Soil Testing & Design

Having your engineering and construction requirements not only fulfilled but exceeded requires verifiable engineering expertise. We know how essential the soil is to your building project, having provided geotechnical services since 1994 to South East Queensland, Brisbane, Gold Coast, Sunshine Coast, Toowoomba, Northern Queensland and Northern New South Wales. Few teams can offer as in-depth an analysis and as trustworthy a report as East Coast Group of Companies.

When You Need A Soil Test

Our geotechnical services are necessary for new build projects, but they’re also a relevant when planning for extensions and renovations. We also provide soil testing for those who want to know everything about the land they’re buying. If there’s been a failure in your property’s retaining walls, support structures or foundations, we can identify whether the soil had any part to play in that.

What We Offer

You need to know that the ground of your project site is safe to work on, what kind of stabilisation your construction projects might need, and what kind of foundations are necessary for the structure. The only way to know that is through our in-depth analysis techniques and comprehensive soil testing services. We are recognised geotechnical experts in the region, with knowledge extending to fields such as the following:

Soil Testing

We provide laboratory testing of the soil, using a variety of samples to determine the necessary engineering parameters required to progress the design.

Dilapidation Reports

In thriving neighbourhoods, there is always the risk that continuous construction and demolition projects in the surrounding area can affect your soil conditions. Dilapidation reports help you understand those changes and can prevent disputes in the event of property damage caused by work nearby.

Services We Provide

Beyond helping analyse the soil, we also provide a variety of designs to best fit your ground conditions:



  • Slab and Footing Design: Whether building a new structure or planning a renovation or extension, the correct footings best distribute the load based on the soil it’s built on.
  • Structural Design: Structural solutions to satisfy your needs, with experience working with materials such as timber, plywood, steel, masonry, and concrete building elements.
  • Retaining Walls: Cantilever, gravity and anchored walls that support soil laterally. We can obtain accurate geotechnical parameters to allow a safe and economical design.
  • Swimming Pools: Soil shrinkage and swelling around the structure due to moisture can cause cracks in the foundation. Adequate geotechnical information prior to design stage is crucial to mitigate against these issues.


If you’re taking on a new construction project, buying new land, or finding the cause of a failure, East Coast Group of Companies offers the most comprehensive soil investigation and testing services.
