BC’s terrain ranges from sandy coastal soils to mountainous bedrock. The choice of GPR, seismic, electromagnetic, or resistivity methods depends heavily on site-specific soil composition:

• Clay soils reduce GPR effectiveness

• Sandy soils improve radar clarity

• Rocky or densely compacted soils may require seismic profiling or magnetic methods

Terraprobe’s geophysicists assess your site to match the right methods to your subsurface conditions.

Timing matters. Moisture content affects radar penetration and signal clarity. We schedule surveys during optimal conditions and adapt methodology based on seasonal and environmental factors like:

• Freeze-thaw cycles

• Water table levels

• Rainfall patterns

We bring localized expertise in BC’s Lower Mainland, Fraser Valley, and interior regions to mitigate weather-related risk.

What are you looking for—and how deep?

• Shallow surveys (0–2m): Ideal for locating utilities, shallow foundations, or archaeological features

• Deep surveys (>2m): Needed for bedrock profiling, groundwater mapping, or geotechnical data

Terraprobe develops a custom survey design based on your goals, adjusting techniques and equipment accordingly.

Surveying in built environments adds complexity:

• Interference from rebar, power lines, buried utilities

• Need for advanced signal processing and high-resolution imaging

• Risk of false positives from metallic or reinforced objects

We specialize in high-density data acquisition and advanced filtering to deliver reliable results in urban environments like Vancouver, Surrey, and Burnaby.
