Ground Penetrating Radar
Ground Penetrating Radar (also known as Ground Radar, GPR, Impulse Radar Ground Probing Radar, Sub-surface Radar and Surface Penetrating Radar) was originally developed for mapping geological features. It is now increasingly used as an NDT survey technique in Civil Engineering and offers a unique non-invasive and non-destructive means for the characterisation of the subsurface and subsurface features.

Ground Penetrating Radar (GPR) offers a cost-effective non-destructive (ND) method of building inspection and investigation. GPR can be used to determine construction detail when no as built drawings are available (or to confirm that drawings that are available are correct) and assessing the feasibility of proposed building works.
Ground Penetrating Radar (GPR) is very effective in locating chimney flues in buildings. This can be done with no intrusive works or damage to the building structure. It can be done in occupied buildings with minimum disruption to the occupants. The only requirement is that good access to the walls to be surveyed is available.
Modern concrete floor slabs can be subjected to extremely tough conditions including heavy static and moving loads, impact and abrasion . Warehouse floors in particular can suffer badly. Problems with concrete floors can also arise when a change of use occurs and loads differ from the original design. Failure of the concrete floor slab may occur, resulting in costly down time and expensive repairs.
