Terrazzo and Vapor Barriers
Controlling Moisture is Critical
The evolution of terrazzo from a cementitious system to epoxy brings a new concern: controlling moisture. While the cement system developed centuries ago allowed moisture to naturally migrate from the ground or concrete slab and then escape, epoxy-based terrazzo systems do not breathe. That means that if the concrete slab or space below is not controlled, and moisture rises up, epoxy terrazzo will usually fail.
Tile, Marble & Terrazzo
For performance and life cycle advantages, tile,marble and terrazzo are the most durable and beautiful finishes.
