Post-Tensioned Cables Mapping Using Ground Penetrating Radar (GPR), Downtown Calgary, AB

: Post-tensioned cables mapping for a commercial building in downtown Calgary completed by SCANTEC.

: The cables were placed in a grid pattern with 45 inches to 50 inches spacing between bundles in both directions. Each bundle was a group of 2 or 3 tendons. The depth of tendons varied throughout the floor.

: Interpreted post-tensioned cables were marked on the floor with red spray paint.

Post-Tensioned Cables Mapping Using Ground Penetrating Radar (GPR), Kensington, Calgary, AB

: PT cables were identified, marked with depth and location

: Tensioned cables were distinguished from rebar and other objects

: Drilling crew went ahead for the borings

: Underground and embedded lines in slab

: Anomalies found

: The entire floor with concrete lab-on-grade was scanned with 1600 MHz, 900MHz, 400 MHz, 200 MHz antennas and swept with regular EM Radiodetection line locating equipment prior to deep bore hole drilling.

Concrete GPR Scanning prior to Coring and Cutting, Lethbridge, AB

: Slab thickness, rebar size and spacing, depths, voids and location of conduit or critical objects can be determined

: Location of hole can be easily chosen

: Findings were marked on the floor

: Palm antenna can easily scan tight areas and close to walls

: Findings were marked on the floor

Voids location below Concrete, GPR Scanning in Sherwood Park, AB

: Voids area within the dashed line; * mark is recommended test core

: Area 2 with broken water line

: Void area 3

: The scanning helped the contractor to determine the best location to start the investigation and repair the slab
