Terra Firma Laboratories was established in 2005 by Tom Seymour. Inspired to take the leap of faith that is required to run your own business, Tom took on the challenge of taking his skills learned as Laboratory Manager for an local Engineering Consultancy and created Terra Firma Laboratories with the ambition to provide a construction materials testing services and geotechnical laboratory for the construction and mining industries.

Initially servicing the local residential development sites in the City of Casey, from our small laboratory in Berwick, since 2005 we have expanded the range of projects we offer our testing services to include Engineering Geotechnical Design projects, EPA Audited Landfill construction projects, dams and other water storage construction projects, and mining infrastructure construction projects. Our customers are based not only in metropolitan Melbourne but also in regional Victoria, outback Australia and as far afield as Papua New Guinea and Indonesia.

Since 2005 we have grown the business from one two-man laboratory to a business with two on-going Melbourne laboratories, a third branch laboratory in Roebourne, W.A.  and multiple project-based laboratories located anywhere across the country at any one time.
