Providing gravel exploration services throughout Alaska

Surface- or borehole-based geophysical methods often provide insight into subsurface layers such as gravel deposits, bedrock interface, and clay layers in a cost-effective manner.  Geophysical data provides spatially extensive information, compared to drilling boreholes, and so gives more insight at a lower cost - a win-win! We recently demonstrated the success of geophysical tools to find gravel in Northern Alaska.  We're excited to offer this capability to promote cost-effective, rapid exploration for gravel resources!

Surface-based methods are non-invasive, and therefore often safer, cheaper, and quicker than traditional sampling methods like drilling.  Our tools and expertise are able to delineate many subsurface boundaries, including the following, depending on site conditions:

Gravel deposits
Depth to water table
Stratigraphic sequences/layers
Mapping permafrost depth and variability
Depth to bedrock and bedrock quality
Shear-wave velocity profiles
Karst/void detection and delineation
Identifying ice wedges, layers, and mass ice
