Why rely on 1940s technology for your designs? With GSS CSW testing you can:
Avoid the guesswork associated with empirical stiffness relationships
CSW testing provides output as an easy-to-use stiffness profile
Avoid uncertainty over the strain at test measurementsCSW is measured at small strain levels permitting straightforward adjustment to design strains
Avoid the conservatism required by unreliable dataCSW data provides accurate, representative in-situ bulk stiffness values
Minimise drilling of boreholesCSW is non-intrusive, giving data to typically 6 to 10m depth
Avoid lengthy programmes of testingeach CSW test takes only about an hour
Reduce investigation and testing costseach CSW test costs only about the same as a plate load test
Find out how innovative Continuous Surface Wave testing by GSS can provide rapid, accurate, &
cost-effective stiffness profiles for value engineering your project.

Simple test setup
GSS-manufactured test equipment is simple,
reliable and non-intrusive – so very low risk.
Each test takes only about 30 minutes to
complete with no need for boreholes, rigs or
heavy plant.
Testing is operated from a standard 4WD,
but equipment is fully portable if required.
Reliable on-site data control
Bespoke GSS C-DAS software controls testing
and provides automatic data quality control to
optimise data in the field.
Immediate preliminary results
Immediate display of test data and simple
stiffness profile displays are output &
compared on site – allowing rapid initial
assessment of ground stiffness and ground
conditions.Advanced data processing
Advanced data processing permits provision of a
layered stiffness profile (Go & E) provided as a simple
spreadsheet output, with full user control over input
values and design strain softening value. Detailed guidance & engineering support
Experienced Chartered Geotechnical Engineer
support with a range of free-to-use guidance
documents and references.
CSW testing applications include:
Foundation design optimisation
Earthworks control testing
Ground improvement design & validation
Ground profiling & 3D stiffness modelling
Mineworkings investigations & treatment
validation
Seismic & liquefaction assessments
