Reading bridge over the river Thames.

GPR bridge investigation

On bridges GPR can be used to map reinforcement, locate post-tensioned tendons, determine general construction detail, thickness of construction and much more…

GPR surveyor scanning the gas holder base to determine the thickness.

Gas holder base thickness measurement

GPR case study: How we used GPR survey methods to determine the gas holder base thickness non-intrusively, with access to one side only.

Concrete floor slab in car park

Concrete Floor Slab Surveys

Our GPR surveys provide a fast and efficient NDT means of surveying concrete floor slabs to determine construction detail and identify defects.

Tendon ducts being cast into concrete slab

Locating post-tensioned tendons in concrete

Our NDT GPR surveys can locate tendons, including their depth, in pre-stressed and post-tensioned concrete. Essential prior to cutting, coring or drilling.

Concrete reinforcing bar location survey with rebar positions marked up in situ on slab soffit.

Concrete reinforcing bar location and other site mark-up surveys

Non-destructive concrete reinforcing bar location surveys using GPR. If you need a simple rebar location, we can mark up rebar positions on site.

Rebar reinforcing cage.

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.

Stone retaining wall by the sea.

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.

GPR surveyor scanning floor slab with GPR for thickness measurement.

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.

Technician coring concrete slab - always locate rebar before coring.

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”.
