About this Service
A Kalispell threat assessment evaluates Flathead Valley properties and mountain-edge lots for glacial valley soils and groundwater risk. It fits homeowners and developers in the Flathead Lake area planning new bunkers or conversions near foothills.
Field work typically includes hand-auger samples, two or more boreholes, and a groundwater survey to size perimeter drains and sump systems. The assessment accounts for frost heave and wet winters, and recommends HDPE waterproofing membranes and insulated thresholds where seasonal runoff is high.
The outcome is a site-specific report with depth, waterproofing, and drainage specifications suitable for structural engineering and permitting. If perched water tables appear, plan for deeper excavation or raised access to avoid persistent damp conditions.
