Dispersion Apparatus

The dispersion apparatus works with the Pinhole Test to identify the dispersive characteristics of soil. Additionally, it helps determine the stability of clay soils used.

The test replicates the conditions of water flowing along a crack in a soil mass. The water flows through a 0.041 inch drilled pinhole in a compacted soil sample.

The dispersibility of the sample results from calculating the flow rate of water through the pinhole, evaluating the cloudiness of the water, and measuring the final size of the pinhole. The final test results reveal the cost-effectiveness of projects and identify potential safety issues.
