Applications | Geotechnics, Engineering, Mining, Energy & Research

**QC in the field.** Check every record live and generate a report while still collecting — from the comfort of your vehicle.

**Non-intrusive.** No drilling, no excavation — just geophones on the surface.

**Deploy anywhere.** Soil, pavement, slopes, shorelines and tight urban lots.

**Compact.** The full system packs into a single rugged case.

**Easy travel.** Small enough to fly with — take it to any project site.

Three ways to work with us

Software, processing, or the full system.

VsSurf 1dS — 1D S-wave velocity profile

1D S-wave velocity profile showing earthquake ground-shaking potential site class per the IBC and depth of subsurface layers.

Software

VsSurf 1dS

For making 1D shear (S-) wave depth-velocity profiles using passive and active seismic sources:

Determine earthquake ground-shaking potential per NEHRP and/or IBC — Vs100 (feet) / Vs30 (meters)
Constrain the depth and velocity of subsurface layers
Estimate density & rheology of earth & rock
Understand rippability and excavation costs
Reads both SEGY and SEG2 file formats
Auto-generate a final report

Industries

Where ReMi® earns its keep.

01

Geotechnics

Reliably and quickly determine critical subsurface information for less; such as earthquake ground-shaking potential per the International Building Code (IBC), depth and velocity of subsurface layers, and rheologic properties of earth & rock.

Geotechnics solutions →

02

Engineering

Confidently and independently evaluate the depth, lateral extent, and rheologic properties of subsurface soil and rock layers. Constrain the location of faults and slides and determine the effectiveness of compaction and earth remediation projects.

Engineering solutions →

03

Mining

Reduce costs by covering your mineral resource ground reliably and rapidly to understand depth to bedrock, locate faults, estimate excavation and hauling costs, constrain the location of ore & waste rock zones, and monitor earthen structures such as tailings retention dams.

Mining solutions →

04

Energy

Non-invasively image basin-wide earth structure to over 10,000 feet (3,200 m) depth, to assist in developing drill targets for producing energy resources in commercial quantities.

Energy solutions →

05
