Soil Testing

Salinity Soil Test

Our Salinity Soil Testing measures both pH and salinity in order to determine an exposure classification level, in accordance with relevant Australian Standards. High salinity (soil salt level) may cause corrosion of screw piles or steel reinforcement within concrete. This test informs both building designer and design engineer regarding selection of appropriate materials to achieve the structure’s required design life.

When is it required?

Salinity testing and exposure classification level is used to determine design parameters within aggressive soil environments — giving builders and architects minimum concrete and steel requirements for the foundation system.

Special mitigation measures may include:

  • additional concrete cover and strength
  • double vapour barrier
  • additives to the concrete mix
  • galvanisation of steel screw pIles.

One engineer for all your needs

Every building project is different, requiring a combination of engineering disciplines. From bottom to top, our engineers can work on soil testing and foundations, all the way up to frame and roof truss design and even inspections. We believe these shouldn’t be thought of as separate, unrelated services.

Whether you’re renovating, extending, building a brand new home, or putting in a pool, you can gain significant benefits from understanding (in advance) the full range of engineering services you might need — and from using the same engineer for all these services.

Key advantages of integrated services

STA is a one-stop engineer with a service range that delivers three key advantages:

  • Save time and money

Pre-planning your engineering needs means you won’t have to keep re-booking an engineer when you need a particular service. It creates efficiencies that cut service times and save you money by pulling together the services you’ll need, at a lower overall price.

  • Enjoy engineering continuity

With all your engineering done by a single organisation, your consultants tap into a deeper knowledge of the site and the project, which leads to high quality outcomes, with more opportunities for innovative solutions.

  • Less risk, more reliability

While STA always takes legal responsibility for its engineering designs, an up-front engineering services package makes it easier to trust our work with a strong mutual commitment, and reduced risk of potential interruption or delay.

How it works

Engineering consideration – We help you think about your project in engineering terms. What specific services might you need?
1
Packaged plan – We develop a plan that packages up all the engineering services you need for your individual home or build project.
2
Prescheduled services – With each service pre-scheduled, we can work more closely with you over the life of the project.
