Chilliwack ground conditions & what they mean for GPR
Local geology: Chilliwack sits on Fraser floodplain gravels and sands with mountain-fan gravels at the valley edges. Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland.
Local building stock: Dairy and berry operations, fast-growing Sardis subdivisions, and military lands with legacy buried infrastructure.

Chilliwack questions, answered
GPR vs X-ray for concrete — which is better?
GPR needs one side of the slab, no radiation permits, no area evacuation, and scans 10× faster at lower cost. X-ray wins only on sub-centimetre detail for congested embeds when both slab faces are accessible. For 95% of BC scanning work, GPR is the right tool.
Can GPR find voids inside the concrete itself?
Yes — honeycombing and consolidation voids reflect distinctly. Common finds in older pours and patch repairs; each gets boundary-marked for the engineer.
How fast can you clear core locations?
Single locations clear in 15–30 minutes including marking. A typical tenant-improvement scope of 10–20 penetrations clears in a half day, same-visit drilling included.
Is the equipment safe to use in occupied buildings?
Completely — GPR emits less RF energy than a phone. No evacuation, no permits, no disruption to tenants or hospital/lab equipment.
How deep can GPR scan in Chilliwack?
Chilliwack sits on Fraser floodplain gravels and sands with mountain-fan gravels at the valley edges. Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland. We select antenna frequency to match — and where local ground limits radar depth, we pair GPR with electromagnetic locating, acoustic methods, or tracer gas so the survey objective is met regardless of soil conditions.
Do you actually work in Chilliwack, or dispatch from elsewhere?
