Good subdrainage is necessary to preserve pavements from pot-holes and cracks that result from water seeping in under the pavement surface. Underdrain systems should be installed to prevent ground water from sseeping through cuts and weakening the subbase materials. Warning signs of the need for subdrains include broken pavements, pumping joints, "checked surfaces", heaving, slides, and deflection. The specific type of subdrain constructed depends upon the nature of the water seepage; i.e. side hill seepage, high water table, surface leakage, and perched water table. The most important requirement for an effective subdrainage system is structural integrity.
