Monolith is a permeable resin bound stone system for exterior floors. Kiln-dried quartz aggregate between 1 and 3 mm is mixed with a single-component, moisture-cured polyurethane binder and the FLOWTECH anti-stick agent, then troweled and compacted over a primed substrate. Each stone ends up locked in place while the spaces around it stay open, and that open structure is what lets rainwater drain down through the floor rather than run off the top of it.

What you end up with is a continuous stone floor that holds its texture underfoot, sheds no loose gravel, has no joints to re-sand each spring and gives weeds nowhere to take hold. It covers the same ground as a resin bound driveway, permeable paving, a stone carpet or an epoxy pebble overlay, with one difference that matters outdoors: the binder holding it together is polyurethane rather than epoxy, so it keeps its color in the sun instead of yellowing.

In most cases it goes over the surface you already have. Sound concrete and asphalt both work, and so does tile once it has been tap-tested and leveled, which usually means there is nothing to demolish, nothing to haul away and no re-grading to pay for. We see it most often on driveways, pool decks, patios and walkways, and it works just as well on courtyards, entry plazas, roof terraces and light commercial exteriors.

How thick it goes down is decided by what will use it rather than by how you want it to look: 3/8″ where people walk, 5/8″ where cars drive, and 3/4″ anywhere wheels turn under load. That one choice then sets everything else on this page, from the number of bags you order to what the material costs you.
