Abstract:
A breathing system for a steel reinforced concrete slab or pile slab allows water to penetrate the slab from both directions, upward and downward, thereby relieving any water pressure differential across the slab. This minimizes stresses on the slab, and maintains the water table. A plurality of apertures are distributed over the surface of the slab, and extend between the upper and lower surfaces. Each aperture may include a pipe. The apertures are evenly spaced apart in between the reinforcing bars, so as not to compromise the strength of the slab. The apertures will allow water to penetrate evenly over the entire surface of the slab. Layers of sand or crushed stone adjacent the upper and lower surfaces convey water to and from the apertures.
