Overview
About this product
Black reflective fire glass with the tumble-finished body that catches flame movement and amplifies it across the bed of the feature, MSI Black Polished Pebbles ships by the bag. Underfoot stability, drainage behavior, and the visual continuity of natural material make this the kind of exterior surface that signals attention to the small landscape details. Set in sand for permeable installations, in mortar on prepared substrate for vehicle approaches, or over pedestals on rooftop and deck applications.
Underfoot, this is the kind of exterior surface that signals attention to the small details, a smoother walk in bare feet, a more confident step in winter shoes, the quiet substance of natural material rather than something poured. Once installed and weathered into the landscape across a season, the surface develops the kind of patina that distinguishes designed exterior work from manufactured paving alternatives.
