This integration of services increases efficiency and accountability, while saving our clients the difficulty of sending different sample types to multiple laboratories.
Basic descriptions of each discipline follow, with additional information available on each of the service specific pages.
Soil Mechanics
Tests include the basic index soils analyses (soil classification, compaction, moisture-density, rigid wall permeability, single-plane and double-plane direct shear); vadose zone hydraulic tests (capillary moisture retention characteristics, Bruce-Klute diffusivity analysis, air permeability); sophisticated design-related strength tests (static and dynamic triaxial shear); and performance/conformance related hydraulic properties (gradient-controlled and flow-controlled back pressure saturated permeability tests, long-term leachate compatibility analyses).
Rock Mechanics
Provided are static and dynamic tests such as uniaxial/triaxial (confining pressure up to 10,000 psi) compressive strength with/without elastic moduli, creep test, differential strain curve analysis, indirect (Brazilian) or direct tensile strength, point load, Schmidt rebound hardness, strain or stress controlled direct shear on intact/fractured rock and ultrasonic pulse velocity. Also provided are index tests such as moisture content, chunk density, porosity, slake durability, freeze thaw, wet dry, Moh’s hardness, Cerchar abrasion and punch penetration excavability/drillibility tests.
Geosynthetics Testing
Applications include large scale design performance or compliance tests such as direct shear testing relative to geosynthetics & soils interface friction, geostatic puncture resistance, multiaxial burst analyses, and hydrostatic point stress, as well as more standard index tests, including tensile, tear, hydraulic properties (in-plane flow and permittivity), puncture, bonded seam strength, and mass, thickness and dimensional stability.
