This Porous Stone is 3in (76.2mm) diameter, 0.50in (12.7mm) thick and constructed of quality aluminum oxide material. The rigid disc supports either end of cylindrical soil samples while allowing two-way flow of fluids.

We offer a complete selection of Porous Stones for a variety of laboratory geotechnical applications, including triaxial shear, permeability, direct shear, consolidation and more. 

Porous stones allow water and other permeants to flow and be measured during test procedures while minimizing the fine particles within the sample from potentially entering the test system. High quality stones have a permeability range of 15-18ft3 (424-510l) of air per square foot and an average pore size of 179um. All Porous stones are available for immediate shipment.

  • Sintered Bronze Round Porous Stones are available in variety of popular sizes, and have 0.125in (3.2mm) or 0.25in (6.3mm) thicknesses.
