We have developed a seafloor direct push system enabling us to perform either cone penetrometer or dilatometer with true interval seismic tests from the mudline of a river.
We have developed a portable direct push system that can move through a 32-inch wide door opening to access the ground floor concrete slab next to the structure’s footings.
We have performed the deepest dilatometer test in the world at Calvert Cliffs Nuclear Power Plant at a depth of 398 feet. We were the organizers of the Second International Conference on the Flat Dilatometer Test (2006).
The mechanical cone penetrometer probe, invented in The Netherlands in 1932 by P. Barentsen, measures the quasi-static thrust required to push a solid, conical tip having a 60 degree apex angle and a cross‑sectional area of 10 cm2 into the foundation soil
The PMT is typically performed by inserting a cylindrical probe into an open borehole, supporting it at the test depth, and then inflating a flexible membrane in the lateral direction to a radial strain of as much as 40% depending on the probe design.
To enable engineers to provide better professional design services and to save owner’s construction dollars, In Situ Soil Testing, L.C. performs high quality tests and provides comprehensive analyses of soil parameters. This website contains many references for Geotechnical, Structural and Civil Engineers to quickly find technical information about In-Situ tests and their design applications.(Which In-situ test should I use–a designer’s guide)
Founded by Roger A. Failmezger, P.E., F. ASCE in 1995, In-Situ Soil Testing, L.C. started with the purchase of a DMT/CPT truck originally owned by the University of Florida and designed by Dr. John Schmertmann (history of truck by Dr. Schmertmann). It was the first direct push truck in North America and still operates well today. The company has expanded significantly and owns a wide variety of in-situ soil and rock testing equipment. We routinely perform dilatometer, cone penetration, pressuremeter (soil and rock), borehole shear (soil and rock), and ko step blade tests. Unlike other firms who recommend only one test, because that is all that they own and can do, we recommend the most appropriate test(s) for your project’s needs.
