Locating Under-floor Heating Pipes

GPR (Ground Penetrating Radar) can be used to non-intrusively look beneath the surface to detect and map the locations of under-floor heating pipes. This can be performed in properties with under-floor heating prior construction works which require drilling or breaking the surface to ensure that the under-floor heating pipes are not damaged.

Why use GPR to map the locations of under-floor heating pipes?

Ground Penetrating Radar is a completely non-destructive technology (NDT) which can locate and map the positions of under-floor heating pipes without causing any damage to the surface. GPR works by transmitting a signal into the floor and receiving reflections which are caused whenever the signal passes from one material to another. GPR will work on any floor covering that is not conductive (doesn’t contain metal), and the heating pipes themselves will show up clearly in the GPR data because they are significantly different from the surrounding, homogenous material (usually screed).

How a GPR survey to map the locations of under-floor heating pipes is performed

Our GPR surveyors will attend site and using the latest advanced Ground Penetrating Radar technology, locate the under-floor heating pipes by performing a series of scans across the surface in a closely spaced grid. The spacing between GPR scans will need to be close enough to map the exact paths of the under-floor heating pipes including any deviations and, because GPR requires direct contact with the floor to work, the floor must be clear and unobstructed for the survey to be performed.

Mapping the locations of under-floor heating pipes

A GPR survey to map the locations of under-floor heating pipes can be applied to surveys of any scale – from small rooms and residential areas, to large offices and museums. The heating pipes themselves will often be relatively close together and follow complex trajectories under the floor, this can be difficult or impossible to predict without a survey.

Deliverables from GPR survey to map the locations of under-floor heating pipes

The locations of under-floor heating pipes can be seen in the GPR data and marked directly on the floor surface on site. Alternatively, if a map showing the locations of the under-floor heating pipes is required, it will be more efficient to collect GPR data and save it for office based post-processing and interpretation. In this case the saved data is returned to the office and loaded into our advanced GPR processing software where we apply filters to improve the appearance of the data and then compile it into a 3D view. The heating pipe locations are interpreted from the image and a drawing is produced in CAD.
