MASW
Map near-surface stiffness
Measure shear-wave velocity and ground stiffness in the shallow subsurface to support site classification, foundation design and assessment of ground stability.
Reduce ground uncertainty, before it becomes project risk.
From complete seismic survey delivery to targeted specialist support, we provide the expertise, technology and imaging needed to turn ground uncertainty into usable engineering insight, supporting safer design, more confident planning and smoother regulatory approval.
Do these ground investigation questions sound familiar?
- What subsurface evidence do we need to demonstrate compliance with relevant regulations and support planning approvals?
- How can we identify variations in bedrock depth, weak zones and potential hazards between our boreholes?
- Which survey methods will strengthen our ground model and help target further intrusive investigations?
Who can manage survey planning, permissions, access and delivery within our budget and schedule?
EchoVision plans, manages and delivers seismic investigations that complement your existing ground data, helping you reduce uncertainty, target further investigation and make informed engineering decisions faster.
how seismic can help you
See more of the ground, not just individual investigation points.
Boreholes, CPTs, trial pits and laboratory testing provide essential direct information about the ground — but they only tell you what is happening at specific locations.
Seismic imaging can help connect those points, revealing how ground conditions vary laterally and with depth across a wider area.
By mapping changes in seismic velocity, ground stiffness, geological boundaries and subsurface structure, we can help engineering teams strengthen the ground model, target further investigation and make better-informed decisions before committing to design or construction.
The goal is to provide the right subsurface information to reduce uncertainty around the engineering decision you need to make, fast.
Seismic can strengthen ground understanding across the project lifecycle
Planning and regulatory approval
Provide the subsurface evidence needed to support compliance and progress development.
Site characterisation
Build a more continuous picture of soil, rock and geological conditions across a site.
Ground stiffness and Vs characterisation
Measure shear-wave velocity and ground stiffness to support site classification, foundation design and engineering assessment.
Bedrock and overburden mapping
Define the depth, geometry and variability of competent ground across a site or proposed route.
Weak zones and geological structures
Investigate changes in ground properties, weathering, faults, fractures and other features that could influence engineering design.
Targeted ground-risk investigation
Provide additional evidence around suspected cavities, historic workings, buried features or anomalous ground conditions.
Infrastructure and route investigation
Understand changing subsurface conditions along roads, railways, tunnels, utilities and other linear infrastructure.
Ground stability and monitoring
Investigate or monitor changing conditions around slopes, embankments, infrastructure and areas affected by ground movement.
Investigation optimisation
Use wider subsurface coverage to identify uncertainty and help target subsequent boreholes, CPTs or other intrusive investigation.
Choosing the right seismic method for the ground question.
Different engineering questions demand different approaches to subsurface imaging.
EchoVision combines expertise in MASW, seismic refraction, 2D and 3D seismic reflection, and ambient noise tomography with the practical experience to plan, manage and deliver your investigation. We tailor the methods and survey design to your site and objectives, providing the subsurface insight you need to make informed engineering decisions.
Imaging depth
0m
Towed land streamer
Acquire dense shallow data quickly
Rapidly collect closely spaced seismic measurements across accessible sites and corridors to investigate near-surface variability with minimal deployment time.
Seismic refraction
Define layers and depth to competent ground
Use changes in seismic velocity to map subsurface interfaces, estimate bedrock depth and investigate variation in soil and rock properties.
Ambient Noise Tomography (ANT)
Build a bigger picture of deeper ground structures
Use naturally occurring seismic noise to map variations in shear-wave velocity and reveal larger-scale geological structure, typically from tens to hundreds of metres below ground, without requiring an active seismic source.
Seismic reflection
Image deep, complex subsurface structures in high-definition
Create detailed images of geological boundaries, structures and deeper ground conditions where greater resolution or investigation depth is required.
How we can help
Getting useful seismic insight is not always straightforward.
Getting useful seismic insight means balancing technical requirements with practical constraints, budgets and internal capacity. We help engineering teams overcome challenges such as:
- Selecting the right method, resolution and investigation depth
- Integrating seismic with boreholes, CPTs and existing ground data
- Acquiring reliable data on busy, noisy or restricted sites
- Filling gaps in specialist expertise, equipment and team capacity
- Managing survey delivery within budget and schedule
- Turning geophysical results into useful engineering insight
- Responding quickly when new ground uncertainties emerge
That’s where EchoVision can help.
EchoVision combines decades of seismic experience with modern acquisition technology, specialist processing and practical field delivery to help geotechnical and engineering teams get the ground insight they need, fast.
We can take responsibility for the complete seismic workflow or strengthen an existing ground investigation programme with targeted specialist support.
