Cali Bamboo's marbled, fossilized bamboo flooring offers funky durability through an innovative process of compressing and intertwining the material's fibers. The San Diego-based company says the scratch-resistant planks that result have “twice the density and strength of almost any other flooring,” making them appropriate for use with radiant heating systems and in high-traffic areas.
