Forensic Investigation of a Patio Failure
A patio under construction failed catastrophically, resulting in a back yard full of concrete blocks and rubble fused together with sand and cement. My assignment was to determine the cause of failure. A homeowner had laid concrete unit masonry blocks around the perimeter of the patio. A combination of flowable fill (a mixture of sand, cement, fly ash, and water) and debris were used in the center as a substrate for the slab which was to be poured at a later time. The patio failed during the final pour of flowable fill. The patio failed because the moment created by the fluid pressure of the flowable fill against the wall overcame the adhesive force of the mortar between the blocks.
