Non-intrusive surveys that map the ground between boreholes: layers, rock head, groundwater, voids and buried utilities.
Geophysical surveys read the ground between boreholes without digging. Resistivity imaging maps layers, groundwater and weak zones; seismic refraction and MASW give rock depth and stiffness; downhole and crosshole tests give wave velocities for design; GPR, magnetic and microgravity surveys find buried utilities, voids and cavities.
Large or linear sites before drilling, limestone and karst areas, rock-head mapping for piling, groundwater searches, slope and dam investigation, and utility detection before excavation.
Your site, the structure and what the design needs to know.
Test locations, methods and the reporting you need.
Testing, drilling and sampling on site by our field team.
Logs, plots and test results for your engineer.
No. It fills the gaps between boreholes and shows where to drill. Boreholes confirm what the survey sees.
Resistivity sections to map layers, groundwater, weak zones and cavities.
P-wave velocity sections for rock-head depth and rippability.
Shear-wave velocity profiles for ground stiffness and site class.
P- and S-wave velocities measured in boreholes for design parameters.
Pile length measured from a borehole beside the pile.
Radar profiles to locate buried utilities, voids and shallow features.
Gravity readings to detect cavities and sinkholes in limestone ground.
Magnetic readings to find buried metal objects and geological contacts.
