Northamptonshire, GB

As the founder and director of Groundcore Ltd, I transformed hands-on experience in landscaping, construction, and groundwork into an innovative, nationally recognised business. Groundcore specialises in high-performance, eco-friendly groundwork solutions for outdoor buildings, with a strong focus on quality, durability, and sustainability.My flagship innovation is the G-Core Eco Base System—a lightweight yet incredibly strong sub-paviour tray made from recycled polypropylene. This SUDS-compliant solution supports up to 150 tonnes per square metre and integrates seamlessly with pipework and electrical cabling, making it the perfect foundation for sheds, garden rooms, and other outdoor structures. The G-Core Eco Base System embodies our commitment to sustainability while providing practical, long-lasting performance - all without the mess or environmental impact of concrete.Patents for the G-Core Eco Base System were granted in the UK and across almost every U.S. state by 2021, establishing Groundcore as a global pioneer in modular, eco-friendly groundwork technology.Groundcore is built on a foundation of quality, trust, and forward-thinking design, delivering fully installed outdoor solutions with minimal disruption and maximum durability. From groundwork to final installation, we manage the entire process — ensuring a smooth, professional, and customer-focused experience.Under my leadership, Groundcore continues to expand, staying true to our mission: innovative, practical, and sustainable groundwork solutions, built by tradespeople for tradespeople.
