Thick and consists of a cement matrix and marble aggregate topping mix that is applied directly to the concrete slab using a bonding agent between the cement terrazzo and the concrete slab. The advantages of this material over cementitious terrazzo include a wider selection of colors 1 4 to 3 8 inch 6 4 to 9 5 mm installation thickness lighter weight faster installation impermeable finish higher strength and less susceptibility to cracking.

The best thin set system.

Installed in the same manner as for regular monolithic terrazzo but at a minimum 3 8 thickness. Due to its thinness it is also light in weight. A nominal 1 4 or 3 8 thick resin matrix veneer placed upon a level concrete slab. A sand cushion terrazzo floor is the ideal system for a floor where deflection or movement is anticipated.
