At SDA Site Investigation LTD, we provide professional in-situ testing services to assess soil and ground conditions directly on site. In-situ testing is a fast and effective way to gather vital data before construction begins, giving you clear insights without the delays of off-site laboratory testing.
With over 8 years of experience in the industry, we support domestic and commercial clients across Kent, London, Surrey, Sussex, and the South East. Our proactive, safety-first approach ensures that every test is carried out with precision and professionalism.







In-situ testing involves carrying out soil and ground assessments on-site using specialist equipment. Unlike laboratory testing, the results are available immediately, allowing you to make quick and informed decisions about your project.
These tests help identify:
• Soil strength and stability
• Ground bearing capacity
• Permeability and drainage
• Compaction and density
By understanding these factors early, you can avoid costly errors, delays, or safety risks during construction.
We offer a comprehensive range of in-situ testing methods, tailored to the requirements of your project:
Our team uses modern equipment and proven techniques to deliver reliable results quickly and efficiently.
For homeowners, in-situ testing provides reassurance before starting extensions, landscaping, or self-build projects. We provide straightforward reports that your architect and builder can rely on.
