Investigating the permeability or flow of water through rock subjected to high confining pressures is often necessary. The capacity of a rock mass at depth to transmit or yield water is of particular importance when designing deep structures such as tunnels.
Permeability end caps used with ELE-Hoek Cells and constant pressure systems are a cost-effective solution suited to investigating the permeability of rock at high confining pressures in the laboratory. To collect and measure the water which permeates through the rock specimen, a suitable burette such as 25-4540 is recommended. Each permeability end cap incorporates a tubing connector which accepts standard 6 mm tubing, 26-1926, used to connect the cell to the pressure system and burette.
