Concrete Testing Services
GeoShield provides specialist concrete inspection and testing as part of our verification services to ensure that structures are both compliant and resistant to the risks posed by ground gases. Our work supports developers, contractors, and consultants in delivering buildings that are safe, durable, and aligned with regulatory expectations where methane, carbon dioxide, and other hazardous gases may be present.
We take a practical, inspection-led approach
Focusing on how concrete elements and gas protection systems perform in real site conditions rather than relying solely on design intent.
Concrete plays a critical role in forming part of the gas protection strategy on many developments and is often used to gain Gas Protection Points as per BS 8485. At GeoShield, we carry out detailed inspections to assess whether it meets the design intent as a structural barrier.
Rather than simply checking for obvious defects, our inspections consider workmanship quality, interface detailing, and construction sequencing.
“GeoShield provided prompt guidance, site visits, practical installation advice and detailed inspection reports, while remaining flexible with inspections and thoroughly testing completed membranes onsite.”
