Pisolite, named for its pea-like shape and size, is a naturally formed small pebble or mechanically produced spherical stone. Typically 5-12mm in diameter, it is smooth and often gray, white, or beige. Our Pisolite is uniform in size, low in fines, and offers good drainage and aeration. In construction, it's used for exposed aggregate finishes. In horticulture, it serves as an ideal topdressing and seed cover, effectively retaining moisture and preventing soil erosion, while also being a refined material for landscape paving.
