Core Drilling and Extraction Services

Core Extraction

Logo featuring two blue gears and text 'Construction Site Testing Ltd'.

Our Coring Services provides precise and reliable sampling of hardened concrete, asphalt, and other construction materials. Core samples are taken to determine in-situ strength, density, and durability, as well as to assess the compliance with design specifications. This method is invaluable for investigating existing structures, verifying the quality of placed materials, and supporting refurbishment or remedial works.
