Weep hole
Weep hole
A "weep hole" is a drainage pipe equipped with a check valve. It is used to prevent cracks, uneven settlement, and uplift of structures caused by uplift pressure and scouring effects from infiltrating water or seepage flow. Excessive groundwater pressure pushes the rubber valve upward, releasing water into the drainage channel and preventing cracks and uplift in the structure.
