Post-tensioned cables mapping using Ground Penetrating Radar (GPR).

Using GPR scan to look for electrical boxes covered with tile by mistake. This simple scanning could actually save a lot of time and money for the contractor. This is a Palm antenna which is very small and able to scan very tight areas.

Special GPR scanning project at hospital basement to map out drains, water lines, power and other utility, Calgary, AB.

The entire floor with concrete lab-on-grade was scanned with 1600 MHz, 900MHz, 400 MHz, 200 MHz GPR antennas and swept with regular EM Radiodetection line locating equipment prior to deep borehole environmental drilling. Ground Penetrating Radar scanning in Red Deer, AB.

Using a GPR Mini Structure Scan to map rebar and conduits prior to coring through a suspended slab for new plumbing in Banff, AB. This compact scanner was used due to a lot of ceiling scanning required for the project.

Mapping rebar and electrical lines embedded within the slab before coring.

SCANTEC helps customers:

To map reinforcement within concrete slabs such as rebar, post-tensioned cables etc.
To identify critical Targets within and below concrete slabs such as conduits, buried objects, utility etc.
To perform slab analysis such as thickness and rebar spacing, pattern etc.
To determine potential voids, leakage or cracks within or underneath the slabs

Working with us prior to cutting, coring to safely avoid any accident by hitting live electrical cables or expensive repair for your projects. We are more than happy to answer any questions regarding GPR applications, capabilities or even limitations with specific projects.

Ground Penetrating radar (GPR) is nondestructive method uses electromagnetic radiation in the microwave band (radar pulses) to image the subsurface. Signals from buried objects or structures are reflected and detected by the receiver. For concrete applications, we can detect embedded objects within the slab such as reinforcement steel, rebar or any other critical targets such as electrical conduits. We can also determine the changes in the material properties to locate potential voids, cracks, and rebar deterioration.

DETECTION OF PIPES AND CONDUITS – CONCRETE SLAB-ON-GRADE LOCATING

Underground pipes and conduits scanned at a gas station.

A typical underground pipes and conduits scan at a gas station. Max depth around 5ft from surface with a 400 MHz GPR antenna.Vent pipes, production pipes to pumps as well as power and communication utilities can be located within this depth window.

This locating is performed prior to saw cutting or trenching through the slab to install new plumbing drain pipe, to run a new electrical cable in the floor etc.

DETECTION OF REINFORCEMENT – STRUCTURAL SLAB

Concrete analysis and rebar mapping for a wing wall using GPR.

Concrete analysis and rebar mapping using GPR for a wing wall .

Most of structural concrete slabs are reinforced with rebar or post-tensioned cables. Reinforcing steel location is determined prior to remedial works to ensure the integrity of the structure will be preserved during cu

tting and coring through the slabs.

The scanning process also helps engineers to plan the locations of the boreholes as well as fulfill any missing record of the slabs.
