Sometimes the position of reinforcement, tendons, pipes, conduits, services, etc. need to be located so that they can be avoided when drilling or cutting. In this scenario a full report and CAD plot is often not required. An on site mark-up survey offers the quickest and most efficient means of providing the required information.
Ground Penetrating Radar detects changes in the sub-surface, therefore it will detect metallic and non-metallic features making it suitable for detection and location of rebar, tendons, underfloor heating pipes, voids and other features within concrete. Results can be interpreted in real time making it quick and efficient method.
High frequency GPR offers several advantages over other, more traditional methods, such as Cover Meter and Ferroscan:
Our GPR surveyors are trained in house and have considerable site experience. This experience and expert knowledge means that we offer a reliable and quality service, helping to reduce risks during the cutting and drilling stage to an absolute minimum.
Although site mark-up surveys usually involve small local areas (e.g. for a single fixing or slab penetration), they can also be used for larger areas if required.
Generally, no off-site data processing is required. The GPR data is inspected by our surveyor in real time using the display screen on the GPR control unit. The position of detected features is picked in the data and their position marked up on site using chalk, engineers crayon or paint.
