PTG Consulting’s Sunshine Coast geotechnical team delivers expert ground investigation, testing and design for residential, commercial and infrastructure projects across the Sunshine Coast, Noosa, hinterland and beyond.

Based in Baringa, our team brings CPEng, RPEQ, RPEV and NER certified expertise to every project — from single residential site classifications through to complex multi-borehole investigations for major infrastructure and development projects.

What sets our Sunshine Coast operation apart is the integration of our onsite Protest CMT construction materials testing laboratory. Drilling, sampling, lab testing and reporting all sit under one quality-assured workflow — meaning fewer interfaces, faster turnaround and a single accountable team across the life of your project.
