At SDA Site Investigation LTD, we provide thorough and reliable site and ground investigation services for both domestic and commercial projects. Before any construction begins, it’s essential to understand the soil, rock, and ground conditions beneath your site. With over 35 Years drilling experience and 8 years trading experience, our team delivers accurate results that allow you to make informed decisions and move your project forward with confidence.






A site investigation gives you a detailed understanding of the land you’re building on. Without it, construction risks increase, potentially leading to costly problems later.
Key benefits include:
By investing in a proper investigation at the start, you ensure your project has a safe and stable foundation.
We use a combination of drilling techniques, soil sampling, and in-situ testing to gather accurate information about your site. Every project is tailored to meet specific requirements, whether it’s a domestic extension or a large-scale commercial build.
For homeowners, our site investigations ensure your new build, extension, or landscaping project is carried out safely and compliantly. We provide easy-to-understand reports that your architect and builder can use with confidence.
We are trusted by developers, contractors, and architects across Kent, London, Surrey, Sussex, and the South East. With a proactive approach and the ability to work to strict deadlines, we deliver the accurate data required for safe, large-scale construction.
