NBCC Division B and ASTM D6391 set clear requirements for hydraulic conductivity data, and in Kamloops the semi-arid climate and stratified glacial deposits make desk estimates unreliable. The Thompson River valley often hides perched water tables and silty lenses that laboratory remolding cannot capture. Our team runs the Lefranc test in soil and the Lugeon test in bedrock, delivering site-specific permeability values you can use directly in dewatering design, excavation planning, and foundation drainage. Because Kamloops sits where lacustrine silts meet fluvial sands, guessing the coefficient of permeability can cost you weeks of delay. We measure it in place, under actual groundwater conditions, and report results that hold up to municipal plan review.
A single Lugeon test in fractured Kamloops basalt can reveal flow paths that borehole logs alone will never show.
