  "summary": "Sheet count of welded wire mesh needed to reinforce a slab, with overlap.",
  "description": "Welded wire mesh (commonly 6x6 W1.4xW1.4, sold in flat sheets or rolls) is a standard light reinforcement for residential slabs and patios, laid across the full slab area before the pour to control surface cracking as the concrete cures and shrinks. This calculator takes your slab area and the coverage size of your mesh sheets, commonly 5x10 feet (50 sq ft) or 4x8 feet (32 sq ft) for flat panels, then divides your total area by the sheet's coverage, rounding up and layering in an overlap allowance since adjacent mesh sheets need to overlap by at least one full grid square (typically 6 inches) where they meet to maintain continuous reinforcement across the slab. Sheets should be positioned roughly at the mid-depth or slightly upper-third of the slab thickness rather than laid on the ground, since wire mesh only resists cracking effectively when it's actually embedded within the pour rather than sitting at the very bottom where the concrete flows over top of it.",

    {
      "q": "How much overlap does wire mesh need between sheets?",
      "a": "At least one full grid square, typically about 6 inches for standard 6x6 mesh, so the reinforcement stays continuous across the seam rather than leaving a gap in coverage."
    },
    {
      "q": "Where should wire mesh sit in the slab?",
      "a": "Ideally at roughly the upper third of the slab's depth, supported on small plastic or wire chairs so it doesn't sink to the bottom during the pour — mesh left on the ground beneath the concrete provides essentially no crack control."
    },
    {
      "q": "Is wire mesh the same as rebar?",
      "a": "No, wire mesh is a lighter-gauge grid meant to control surface cracking in light-duty slabs like patios and sidewalks, while rebar provides real structural reinforcement for load-bearing or vehicle-rated slabs."
    },
    {
      "q": "What size wire mesh is standard for residential slabs?",
      "a": "6x6 W1.4xW1.4 (sometimes labeled 6x6 10/10) is the most common size for patios and sidewalks; heavier-duty W2.9xW2.9 mesh is used where more reinforcement is warranted."
