Practical Advice. Trusted Experience.
Geotest Services supports development and construction projects by providing integrated geotechnical, environmental and laboratory services across Sydney, the Central Coast, Wollongong and regional NSW. Our team works across the full project lifecycle, from early site assessment and investigation through to construction support and compliance verification.
Our capability spans contaminated land assessment, geotechnical investigations and materials testing, with advice informed by local ground conditions, regulatory requirements and construction experience. This integrated approach supports early identification and effective risk management, helping projects progress efficiently from planning through to completion.
Established in 1999, Geotest Services operates from its main office in Blacktown, with additional offices on the Central Coast and in Wollongong.
