Locating underfloor heating pipes
Our GPR surveys provide a fast and efficient NDT means of locating underfloor heating pipes. Works for metal and plastic. Locate before you cut or drill!
GPR survey
Rebar mapping and concrete imaging surveys
High-resolution GPR rebar mapping, reinforcing steel location and concrete imaging surveys to depths of 400mm. Superior resolution to other methods.
Retaining wall surveys
Our non-intrusive GPR surveys can determine retaining wall construction detail, thickness and identify defects. Access is only required to one side.
Slab thickness measurement surveys
Non-intrusive surveys to provide slab thickness readings for concrete slabs, screed layers, bridge decks, road construction and more. Only one-sided access required.
Wall Thickness
Need to determine wall thickness or party wall detail but only have access to one side? We can help. Our GPR surveys can determine wall thickness, wall construction and more….
Void detection and location
Our GPR surveys can detect voids beneath slabs. By scanning on a regular orthogonal grid, the void location and extent can be determined and plotted.
Sinkhole detection
GPR is an excellent non-intrusive survey technique for sinkhole detection and location. We typically use a dual-frequency GPR system…
Pile cap location survey
Need to locate pile caps? Sandberg can undertake non-intrusive pile cap location surveys and determine slab thickness and reinforcement distribution.
Construction Detail Verification
Using GPR to verify construction detail and compliance with current legislation and standards. Suitable for floor slabs, concrete and masonry walls…
Why you must locate reinforcing steel in concrete before you drill
“Locate concrete reinforcing steel before you find it with your drill bit, core barrel or saw! Work safe and avoid dangerous and costly hits”.
