Geotechnical & Environmental Consulting · Cape Town
Understanding what lies beneath.
So you can build, buy and develop with confidence. Ground and environmental investigations for developers, industry, mining and finance across the Western Cape.
01 · Who we are
A site can look ordinary and still carry a risk that adds millions to a build.
TNB Environmental Solutions is a South African geotechnical and environmental consultancy. We help developers, industry, mining operations and financial institutions understand what is in the ground before they build on it, buy it or take responsibility for it.
Our work sits where engineering meets environmental compliance. We investigate, test and report so that decisions are made on facts, not assumptions, in language that engineers, authorities, banks and legal teams can all act on.
Our mission
Accurate, independent geotechnical and environmental information that lets our clients build safely, comply fully and manage environmental risk with confidence.
Our promise
Clear, defensible reports that stand up to scrutiny from competent authorities, engineers and reviewers, delivered on time and within an agreed scope.
Integrity
Findings are independent and reported as they are, whatever the commercial pressure.
Technical rigour
Investigations planned and run to recognised South African and international standards.
Clarity
Reports written to be understood and acted on, not filed away and forgotten.
Responsiveness
Honest timelines, and communication that continues through the whole project.
