Compliant IBC Site Class + Depth & Thickness of Layers in 30 minutes with ReMi™ Software & Systems

Rapidly and cost-effectively determine subsurface ground conditions for geotechnics, engineering, mining, energy, and research.

Geotechnics

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

Save cost 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.
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.
Research

State-of-the-art seismic data processing software for research, teaching, and collaboration on a local or planetary exploration scale.

"I've personally used ReMi since 2005 on hundreds of sites at this point, and is my goto method for shear wave velocity to 100'+ (usually 300'+) even above DHS, CHS, SCPT and refraction surveys. I've used the method on small retail sites to industrial sites to deep TBM tunnels to levees to power/nuclear sites...with and without surface coverings (such as pavements)...many of which were blind surveys. The method provides invaluable data in seismic site class determination and especially SSSA w/ SRA per ASCE7. Many thanks for your whitepapers and expert support thru the decades!"

Quick and Easy to Use

VsSurf™ ReMi™ software gives every user the ability to get geologic and geophysical subsurface information for geotechnics, engineering, and geotechnical engineering applications - autogenerate a report with an accurate and ASCE 7-22 compliant seismic site classification in less than 30 minutes. The analysis is conceptually simple - you can train your field crews and leave the field knowing you have a result that is accepted by building authorities around the world.

“New Albion Geotechnical has worked with Dr. Louie on numerous occasions, with applications ranging from challenging design projects to applied research. The use of refraction microtremor investigations to develop shear wave velocity (Vs) profiles for dynamic site response analysis and nonlinear soil-structure interaction has been the primary focus of our project work. We have always benefited from his insights, thorough review of data, and practical perspectives. Dr. Louie has provided assistance with Vs data from his archives, review of refraction microtremor data and interpretation developed by others, and with the development of project-specific requirements for efficient, reliable surface wave investigations. We consider the project-specific measurement of Vs an integral part of our geotechnical site characterization for seismic applications and look forward to continuing interaction with Dr. Louie and Terean.”

Methods accepted in both industry and academia

ReMi™ software enables small and large institutions to give their students the practical training that the industry demands while facilitating research projects. VsSurf analyses are backed by dozens of peer-reviewed publications.

“Let me start by saying that the VsSurf software is very user friendly! Secondly, the training and support that comes with VsSurf is unmatched! Alison [Lead Geophysicist & Operations Manager - Terean] is definitely focused on making sure that the client is familiar and knowledgeable with both the software, and the field equipment used to obtain the data. The expertise of the Terean Team is simply amazing!”

Perform non-intrusive surveys in traffic-heavy urban areas

ReMi™ software gives users a ground investigation method that is proven to work in traffic-heavy urban areas. Ideal for real-world geotechnical and engineering services. Find the depth to interfaces, profile landslide blocks, assess aquifer volume, and evaluate rippability at the noisiest sites.

"The results from the last job I did turned out great – the Vs100 came within 3 ft/s of seismic CPT down to 100 feet."
