Soil mechanics

At the forefront of Soil Testing for over 70 years, Wykeham Farrance (WF) has been instrumental in the development of internationally recognized test systems that are capable of replicating complex phenomena in a laboratory environment.

A member of CONTROLS since 2004, WF’s expertise, coupled with 60+ years of CONTROLS' leadership in construction material testing equipment, gives you access to a range of expert Soil Testing Systems that are innovative, easy to use and affordable.

CONSOLIDATION TESTING

The typical Consolidation test determines the rate and magnitude of consolidation of a soil specimen. Wykeham Farrance provides an extensive offering of consolidation testing equipment to satisfy the needs of any soil laboratory.

From standard front-loading oedometers available in analog or electronic versions to the fully Automatic Computerized Oedometer (ACE EmS) that comes loaded with Electromechanical Servo-actuation (EmS) technology. In addition to the most common oedometer test also Constant Rate of Strain test (CRS) and hydraulic consolidation are also available.

SHEAR TESTING

Direct/residual shear test is used to measure the shear strength properties of soil. Wykeham Farrance testing equipment ranges from manual direct/residual shear machines up to the fully automatic direct/shear machine (SHEARMATIC EmS) that comes loaded with Electromechanical Servo-actuation (EmS) technology.

The Large Shear Box machine, ideal for soil sample and other materials that contains large particles, is also available. Want to investigate the residual shear strength by applying the shearing action for a large displacement of the soil sample? The ring Shear machine, also known as Bromhaed Apparatus, is what you need. Meanwhile, the Laboratory Vane test apparatus offers a rapid method of determining soft soil shear strength, when an immediate value is required.

DYNAMIC TESTING

Dynamic properties of soil such as stress-strain characteristics have been recognized as crucial in many aspects of construction design.

There are several types of geotechnical engineering problems associated with dynamic loading, some example includes: wave propagation, machine vibration, seismic loading, liquefaction, and transient cyclic loading. Our Dynamic triaxial system (Dynatriax EmS), Resonant Column/Torsional Shear and Cyclic Simple Shear are designed to reproduce in the laboratory these unusual in-situ events with the highest accuracy.
