Porous Stones

Porous Stones provide solid support at both ends of soil specimens while allowing free passage of water for triaxial, permeability, consolidation, direct or residual shear, and other laboratory soil tests. They have a permeability range of 15 to 18ft³ of air per minute, per square foot, and an average pore size of 179µm. They are made of quality aluminum oxide and come in round or square shapes.

Round stones are used in triaxial, permeability, consolidation, and direct or residual shear strength soil testing. They are available with 0.25in (6.35mm) or 0.5in (12.7mm) thickness and range in diameter sizes from 1.400 to 6.00in (35.6 to 152.4mm).

Square stones are used in testing direct or residual shear strength. They are available with 0.25in (6.35mm) thickness and range in sizes from 1.953x1.953in to 3.985x3.985in (49.6x49.6mm to 101.2x101.2mm). A 12x12in (304.8x304.8mm) square Porous Stone is also available with 0.5in (12.7mm) thickness for use with the High Capacity Geosynthetic Direct Shear Machine.
