Xradar™ Pre-Design for Toronto Restaurant

A new restaurant was being planned in a redeveloped old building in the outer suburbs of Toronto and called Xradar™ to assess the proposed location and map the subsurface of the concrete slabs.


The client had a rough plan of how they wanted to design the space however they needed to core a large number of holes into the slab in order to install a commercial kitchen and a bar. They needed to know everything about the slab and the position of all targets within.


Xradar™ was brought in to execute a Pre-Design Scan of whole restaurant slab. Using our Xradar™ enhanced scanning technology, our skilled technicians carried out the scan of this space marking out all targets within the slab which included service channels, slab bands, dense steel reinforcement and metal conduits.

Xradar used a high frequency GPR survey to achieve the required accuracy and a mid-range frequency GPR to reveal information about the structural details underpinning the area. Several grids with evenly spaced lines were laid out resulting an approximately 350 sqm of total coverage.

The Xradar systems used were carefully calibrated onsite to ensure accurate depth measurements. Data was processed and compiled to produce contoured heatmap style results. Results were presented in a CAD workspace and digital reports delivered.

The Xradar survey was complimented with Vuit 3D laser scanning to achieve accurate, scaled georeferencing of our survey grids, and a convenient way to view and present the asphalt thickness results.

The survey revealed a distinct change in the asphalt thickness due to the structural change to the subsurface that was confirmed with the survey results from the mid-range frequency GPR. The data uncovered not only the asphalt thickness but also the nature and location of the subsurface features such as: beams, voids and structural slab changes.
