At Protest Engineering, we’ll provide consultation and advice for your residential, industrial or commercial project. Our team of highly skilled, geological consultants will diligently work with you from inception to completion of your project, ensuring all standards are met.

We provide concrete testing, rock testing, aggregate testing and across the Sunshine Coast and beyond.

Our NATA accredited laboratories offer extensive options for testing and field services to a wide range of standards. Such soil tests include processes such as sample preparation, weathering and sampling. We also perform tests to determine strength bearing, reactivity, compaction and classification.

With the recent changes to the Queensland Plumbing Laws and Codes, from the 1 st   July 2019 it is now a requirement on all sites with an associated Site Classification of M, H1, H2, E and P to be accompanied by a Sanitary Articulation Design (SAD). A SAD is now required when the underlying soils of a site may be subject to   excessive settlement or surface movement due to a volumetric change of the soils caused by changes in the ground moisture condition .  The range of soil movement dictates the Site classification and as such where it is expected some natural soil movement will occur, articulated joints at key points on a drainage system is required. The articulated joints are required to carry the differential movement between adjacent structures (i.e. a house or retaining wall) and the natural ground around it in order to prevent pipework from shearing and becoming displaced (potential spilling sewage into the ground).

Sanitary Articulation Designs are now mandatory across Queensland and requires a suitably qualified  RPEQ Civil Engineer (or Drainage Designer) to undertake the design. Protest has on team an RPEQ Civil Engineer who is experienced in Sanitary Articulation Designs.

In addition to be able to assist with the Sanitary Design, Protest are also able to assist simultaneously with Effluent Designs and the supporting Geotechnical, Structural Engineering  and Site Investigations.

So, if you have an enquiry please get in contact with our team to see how we can assist on your project.
