In Airdrie, many developments sit on glacial till over sedimentary bedrock, and we often see buried utilities or old foundations that nobody mapped. A GPR (Ground Penetrating Radar) survey resolves that uncertainty quickly. It sends radar pulses into the ground and records reflections from buried objects, soil layers, and voids. For a contractor starting a basement dig or a city planner verifying an old utility corridor, this non-destructive method saves time and prevents costly surprises. We often pair it with calicatas exploratorias when we need physical confirmation of what the radar shows. Airdrie's rapid growth means more infill projects where documented underground information is sparse.
A GPR survey in Airdrie's glacial till can detect utilities down to 3–4 meters, reducing excavation risk by over 80 percent.

Risks and considerations in Airdrie
Airdrie sits at an elevation of about 1,100 meters above sea level, with a growing population that surpassed 80,000 in 2024. As the city expands south and east, new subdivisions are carved out of former farmland where old drainage tiles, buried debris, and abandoned wells are common. Hitting an undocumented gas line or a collapsed well during excavation can halt a project for days. A GPR (Ground Penetrating Radar) survey identifies these hazards before the first shovel. The risk is not just financial — it is also safety-critical when working near high-pressure utilities or in trenching operations. We have seen too many emergency calls that a quick radar scan could have prevented.
Our services
We offer a full range of GPR-based subsurface investigations tailored to Airdrie's development needs.
Utility Locating
Detect and map buried pipes, cables, conduits, and fiber-optic lines before any excavation. We mark targets in paint and deliver a georeferenced plan.
Void & Cavity Detection
Identify sinkholes, abandoned septic tanks, or washed-out zones under pavement. Essential for road repairs and building foundation assessments.
Concrete Scanning
Locate rebar, post-tension cables, and conduits inside slabs or walls. Reduces coring risk and speeds up structural modifications.
Archaeological & Environmental Survey
Non-invasive mapping of buried structures, old foundations, or contamination plumes. Used by environmental consultants and heritage planners.
Frequently asked questions
How deep can GPR penetrate in Airdrie's soil?
Typical penetration in Airdrie's glacial till is 2 to 3 meters with a 200 MHz antenna. In dry sandy layers it can reach 4–5 meters. Clay-rich zones reduce depth because they attenuate the signal faster.
Does a GPR survey work through asphalt or concrete?
Yes. Radar passes through asphalt and concrete with minimal loss. We often scan parking lots and warehouse floors in Airdrie to locate rebar or post-tension cables before coring.
What is the cost of a GPR survey in Airdrie?
A typical residential lot survey (utility scan) ranges from CA$710 to CA$1,460 depending on area size, grid density, and access conditions. Larger commercial projects are quoted per m².
Can GPR find buried plastic pipes?
It can, if the pipe is at least 50 mm in diameter and the surrounding soil is not too conductive. Plastic produces a weaker reflection than metal, but we adjust antenna frequency to improve detection.
Do you provide same-day results?
We deliver preliminary target markings on site within hours. The full report with georeferenced maps and profile images is sent within 2 business days. Rush reports are available for emergency projects.
