The âPerc Testâ. A Perc Test (also known as âPerk Testâ, and more formally known as a Percolation Test), is a soil evaluation that tests the rate at which water drains through soil.
This video portrays what one of the more âcomplicatedâ versions of a perc test looks likeâ¦. As you can see, some situations call for heavy equipment, surveyors, engineers and the like, whereas other situations can be as simple as drilling small holes in the ground (by hand) and taking samples of the soil.
