WHAT ARE MY BENCH SUPPORT REQUIREMENTS?

Please note that this information is the latest available from our various material suppliers and is subject to change without notice.

  1. Granite, Marble & Reconstituted stone
    Natural stone & Caesarstone, Silestone, Smartstone Quantum Quartz etc
    (nominal 20mm slabs with 20mm edge or mitred/laminated apron/edge profile):

    • </= 150mm overhang with no support in 20mm material is permitted to allow a 20mm finished edge; for overhangs over 150mm, substrates are required
    • Extra support rails on edges adjacent to underbench ovens, sinks and dishwashers required.
    • Up to 300mm overhang without additional support (18mm substrates sufficient) at </= 600mm spacing.
    • Over 300mm overhang, brackets, legs or metal frame required to support substrates
    • A minimum of 80mm is required between the front of the bench top edge and cut outs such as sinks or hotplates. A minimum of 50mm is required from the rear of the bench top to cut outs. A minimum of 35mm is required between sink and tap cut outs.
  2. Porcelain 12mm panels
    DEKTON, INFINITY, LAMINAM , NEOLITH & QUANTUM SIX+ 12mm

    • 12mm panels require full 18mm substrates. 40mm mitred edges require 26mm substrates.
    • </= 150mm overhang with no support is permitted in 12mm material to allow a finished 12mm edge; for overhangs over 150mm, substrates are required.
    • For 40mm mitred edges, substrates will need to be 8mm thicker than usual, ie: 26mm substrates in lieu of 18mm.
    • A minimum distance of 50mm must be kept from each cut out; ie: from edge to cut out and between cut outs.
    • Under mount sink cut outs should be the same size as the sink or rebated – ie: material not overhanging.
    • Drainage Grooves, Drainage Sections and Flush Mounting for appliances are not possible.
  3. Porcelain 5, 6 or 8mm panels
    • ONLY TO BE USED FOR SPLASHBACKS or other vertical surfaces. 
    • Not suitable for bench top applications.
  4. Porcelain 20mm panels
    • 20mm panels do not require substrates; however, back to front supports must be fabricated every 600mm and installed along the perimeter of cut outs larger than 600mm.
    • Standard overhang for 20mm is 300mm. Additional support in the form of MDF substrates (or similar) will be required for overhangs greater than 300mm
    • A minimum distance of 50mm must be kept from each cutout; ie: from edge to cut out and between cut outs.
    • Under mount sink cut outs should not overhang sinks – rebated or level with the sink is preferred.
    • Drainage Grooves and Drainage Sections are possible but must be kept to a minimum of 25% of the material; ie: maximum 5mm in 20 mm material
    • Flush mounting of Hot Plates is possible, but it should be noted that the cut out will have rounded corners – not square as per the outline of most appliances.
