Site class in under 30 minutes. A full section from the same data.

Reliably and quickly determine critical subsurface information for less — earthquake ground-shaking potential per the IBC, depth and velocity of subsurface layers, and rheologic properties of earth and rock.

Engineering & Geotechnical

Built for the way geotechnical teams actually work.

Under ASCE 7-22, measured surface shear-wave velocity is the preferred method for site classification. Terēan® products meet all requirements of ASCE/SEI 7-22 Seismic Design (Chapters 11–23), and results are accepted by building authorities around the world.

Your field crews can collect while borings are being logged — drill-rig vibration simply adds energy — and the same 1D site-class data builds a full 2D section, so you can evaluate the lateral extent of layers, locate faults and slides, and confirm compaction and remediation work.

ReMi® for engineering & geotechnical.

ASCE 7-22 site class

Vs100 / Vs30 per NEHRP and IBC, with an auto-generated report accepted by building authorities.

Liquefaction potential

Detect low-velocity zones beneath more competent material and tie them to CPT data for safer designs.

Tie to boreholes

Correlate continuous 2D velocity sections with borehole and CPT data to reduce drilling and validate conditions.

Faults & landslides

Constrain the location of faults and map landslide planes non-invasively.

Compaction & remediation

Determine the effectiveness of compaction, pilings and earth remediation projects.

Noisy urban sites

Proven in traffic-heavy areas, on pavement, on slopes and on space-limited lots.

VsSurf ReMi 2dS® — Mapping Liquefaction Potential — Low-velocity zones beneath stiffer material, mapped across the whole site.

Borehole correlation — image provided by Geocon — A continuous 2D velocity section tied directly to borehole data.

We did the ReMi line first and saw that there was a loose, low velocity layer until about 20-30 ft… We definitely would not have done a 50 ft boring if we did not see the ReMi data first.
