Gilson offers all the equipment you need for measuring different soil characteristics strength including unconfined compression, shear strength, stability, and permeability. 


Soil strength is a key property to evaluate in geotechnical laboratory testing for safe construction of embankments and foundation systems. Soil permeability, or hydraulic conductivity, is an attribute used to evaluate movement of water through soil and is valuable for groundwater and environmental applications.

  • Unconfined Compressive Strength Test Systems offer an efficient method to determine simple strength values for cohesive soils.
  • Triaxial Soil Test Systems provide information about shear resistance, strength and cohesion, to predict slope stability and structural foundation behavior.
  • Flexible Wall Permeability Soil Test Systems determine flow characteristics of water or other permeant fluids through soils.
  • Consolidation Test Systems determine values used to calculate potential settlement of structures.
  • Direct/Residual Shear Machines use pneumatic pressure or dead-weight loading to determine a soil sample’s resistance to lateral shear forces.
  • Granular Soil Permeameters enable permeability determinations for a wide range of particle size distributions.
  • Compaction Permeameters are available in two unique options to measure constant or falling-head properties of remolded or compacted soil.
  • Shelby Tube Permeameter is corrosion-resistant and enables testing on undisturbed soil samples remaining in sections of 3in (76mm) diameter tubes.
  • Slake Durability Device measures abrasion resistance during wetting and drying cycles of shale and other soft rocks used in embankments.
  • Expansion Index Consolidometer is a straightforward and self-contained method for predicting swelling potential of compacted soils.
  • Pin Hole Dispersion Device determines the dispersive characteristics of clay soils by simulating the action of flowing water along a crack in a soil mass. 
Load Frame Components are available under Unconfined Compressive Strength Test Systems, Soil Cement Testing Systems and Triaxial Soil Test Systems.
