Foundation Support of HI Before & After
  • Cracking Tiles in Haiku, HI

    Cracking Tiles in Haiku, HI

    Haiku resident Mark S. had noticed some cracks along his home's walls and one prominent crack along his living room entryway. He made an appointment with Patrick Hooley of NorCal Foundation Support to come take a look at what could be done.  Patrick found that there was a void under the living room’s slab foundation. This void is what was causing the cracks in the entryway floor and along the living room walls. Patrick informed Mark that we could fill this void with PolyLevel which would also lift the slab to level out the floor. Mark went ahead with Patrick’s suggested solution and is glad he did.  The tiles that were previously unlevel are now leveled and a problem of the past.
