GPR surveys

Building inspector abseiling on the outside of a building in London carrying out a Ground Penetrating Radar survey.

We specialise in the innovative use of GPR in the Civil Engineering and Building sectors. Find out more about our twelve most common GPR surveys:

chimney flues in London

Chimney flue location surveys

A fast and efficient NDT method for the locating chimney flues within walls.

Concrete floor slab in car park

Concrete floor slab surveys

Determine reinforcement detail, slab thickness and changes in construction.

Conduits and electrical services on concrete floor slab

Locating services and conduits

Location of service conduits within floor screeds and reinforced concrete slabs.

Stone facade of London building

Detecting embedded metal in masonry

Surveys to locate embedded beams, columns, metal dowels, pins and cramps.

Tendon ducts being cast into concrete slab

Locating Tendon Ducts

Accurate location of tendon ducts in post-tensioned or pre-stressed concrete.

Underfloor heating pipes being covered with screed

Locating underfloor heating pipes

Our site surveys can locate pipes used in the majority of underfloor heating systems.

Reinforcement marked-up in-situ on slab soffit

On-site mark-up surveys

Sometimes a simple site mark-up survey is all that is required. We do that too.

Railway tracks with ballast

Railway ballast thickness and evaluation

NDT surveys to determine the condition and thickness of railway ballast.

Reinforcing cage

Rebar mapping and concrete imaging

High-resolution rebar mapping, far superior to that offered by other techniques.

Retaining wall by the sea

Retaining wall surveys

GPR surveys offer NDT determination of construction detail and thickness.

Void below asphalt road

Void location surveys

Void detection in most materials incl. concrete, stone walls and below concrete slabs.

Two brick walls with a gap in-between for thickness measurement

Wall and slab thickness measurement

GPR surveys to determine the thickness of screed, concrete slabs and walls.
