Union Bay Geophysical Study
Location: Union Bay, Comox Valley, BC
Project Date: Jan 2020
Description: 2D MASW Survey for sub surface soil strata profile. Depth of Till.
work carried out
Two 2D MASW Surveys were undertaken to find the layer boundary between coal waste/midden and glacial till.
It is non-invasive geophysical method and therefore the drilling program and the number of test holes could be reduced. This in turn reduced the cost of the investigation
This provided two cross sectional images to inform engineering decisions.
How was data delivered?
Data delivered by two 2d Shear Wave Velocity Profiles and a Report.
Till depth varied in depth depth and was dipping towards the North East.
