underdrain
Soil drainage pipe
An underdrain is a drain installed beneath the surface—under soil, pavement, or a sports field—to carry away excess water.
Agricultural underdrains prevent waterlogging in fields; underdrains beneath retaining walls relieve hydrostatic pressure.
The verb means to provide with such drainage: The contractor will underdrain the entire lot before laying the foundation.
