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.
