Taking physical samples safely requires strict on-site containment. Before disturbing any suspect material, we apply a surfactant fluid to dampen the area and suppress airborne fibres. Using hand tools, we extract a small, discreet cross-sectional sample right down to the original backing layer, ensuring the laboratory receives an accurate profile of the material.
The sample point is immediately sealed with clear encapsulant or filler to leave the surface stable and safe. Each sample is double-bagged in heavy-gauge polythene bags, clearly labeled on site, and dispatched directly to an independent UKAS-accredited laboratory for polarized light microscopy analysis. Turnaround is prompt, and our final reports translate technical laboratory findings into plain English recommendations.
