StoneLids™ technology... the art & science of stone

NOT EVERY COVER IS CREATED EQUALLY...

While at the forefront of modern technologies, Modern Composites cares about the earth; this is why from packaging to product fabrication we use recycled materials whenever possible. As a matter of fact we use recycled packaging and have reduced the use of resins and plastics in our products to below 15% while other major lid companies use 100% plastic. Find out more about StoneLids™ products below.

About StoneLids

  • Fits all standard skimmers/skimmer rings without modification (custom fitment available for other products)
  • 85% recycled stone materials (extensive research done to reduce the polymer content below 15%)
  • Non porous (Algae will not grow on it's surface)
  • Cool to the touch even while in the hot sun (unlike metal lids)
  • Non slip surface
  • Graffiti resistant (paint and concrete will not stick to the surface, just wipe off or sand to remove blemishes)
  • 3x Stronger than concrete (strength of 12,000 PSI makes StoneLids™ virtually unbreakable)
  • No electrical ground required (unlike metal lids)
  • Easy to cut and drill (the lids can be scored to match the deck pattern)
  • .1Lb per cubic inch (will not blow off in windy conditions)
  • Looks like real stone (because it is real stone – we use 85% stone in our proprietary formula)
  • Easy to store for distribution (packages come in boxes with protective cardboard no larger than a standard skimmer lid)
  • New construction lids available to cover the plastic  ring
  • Available in a variety of colors to match any deck surface (no more white plastic lids to interrupt the fluidity of the deck texture)
  • A complete line of “white goods” replacements are in development for a complete uninterrupted deck solution (drain covers, valve box covers, auto fill lids etc…)
