Overview
About this product
MSI Mixed Polished Pebbles brings natural tempered fire glass to gas firepit and outdoor fire feature work: heat-rated, reflective face, drop-in install over standard burner assemblies. Underfoot, the texture stays comfortable across barefoot summer use and confident under winter shoes, the kind of practical detail that distinguishes residential exterior work from utility deck installs. Set in sand for permeable installations, in mortar on prepared substrate for vehicle approaches, or over pedestals on rooftop and deck applications. Pairs with both formal and naturalistic landscape vocabularies, the surface tightens visually as the planting around it matures into the design.
What this surface delivers is the long view, patios that read intentional after the planting matures, walks that carry their tone through the seasons, pool decks that hold their finish under full sun without fading. The material handles freeze-thaw cycling, UV exposure, and the structural loads of pedestrian or vehicular traffic without dimensional movement or color fade. What this material delivers is the long view, patios that read intentional after the planting matures, walks that hold their tone across the seasons, pool decks that look the same in year ten as they do at install. 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.
