The Floor Edging/Control Cavity wall system will promote breathing and allow moisture to gravitate downward to a drain field/drain tile system.

Control Cavity™ (CC 4800)* and Floor Edging™(FE 8555) System
It works as a cavity weep detail in a furred-out, below-grade poured wall system because it has vertical channels throughout the wall system. The vertical channels allow any moisture that may get into the wall to move down and out of the wall (both sides).
