RE: Preliminary Structural Inspection (1) story existing house structure
Dear Mr. Izedian,
Upon your request on October 09, 2010, we scheduled and performed a field site inspection of your residence foundations located at: 2624 N. Ocean Blvd. Fort Lauderdale, Florida on 10/11/2010.
Upon preliminary review of the exterior CBS walls and exterior slab at your property above the area of tunneling for plumbing repairs and backfill, we did not observe any foundation settlement shifting or significant cracking along the exterior structure.
Based on our preliminary exterior field observations, we only found (2) hairline cracks located at the south side of your property. Such hairline cracking could be the result of either aging of the stucco, shrinkage, or long term settlement due to unsuitable materials below the foundations.
However, we recommend further soil exploration including soil boring test by a certified soil testing lab or interior inspection of the floor and slab. Please note that our findings contained herein are inconclusive subject to further testing and interior inspections.
Based on invoice documents, contractor scope and paperwork transmitted by your plumbing contractor dated 9/23/2010, it was noted that the Ben excavated a trench below house slab in order to repair a broken plumbing pipes. The contractor explained that he backfilled the tunnel with clean compacted sand at north and south sides of the house.
Industry practice usually recommends to backfill the trench or tunnel with flowable fill ( A sand cement mix pumped to fill the hole) or compacted sand. However, since it is very difficult to access the small space between the sand and bottom slab for 100% to compact and consolidate the fill, its recommended to inject flowable fill or grout. It appears that your plumber only filled the tunnel trench with sand, but could not verify if the sand was compacted to a 100% density or if he utilized grout or flowable fill.
