We have had a longstanding relationship with Kel Gray from Subtest for many, many years. Ever since Kel started his own business we have engaged Subtest to carry out all our residential site classifications, waste water designs and slope stability reports. Kel's experience and knowledge of Mackay and surrounding areas is invaluable. Someone with his calibre of local knowledge and understanding in the geotechnical field is hard to find. He is trustworthy and efficient and we highly recommend Subtest to anyone seeking geotechnical services.

Subtest are brilliant to work with - Kel and his team are very professional and very knowledgeable in all aspects of geotechnical. Punctual and very quick to provide reports after inspections. A great service - easy to deal with and by far the best in their field in the Mackay region. Fully recommended for all construction and building and development project works.
