Specifications

For all terrazzo specifications, the NCTA refers to the National Terrazzo & Mosaic Association (NTMA), the central source for terrazzo technical data, details, and specifications. For in-depth information on terrazzo systems, visit the specifications section of NTMA website.

Epoxy terrazzo

A nominal 1/4″ or 3/8″ thick resin matrix veneer placed upon a level concrete slab. Can be specified with glass, synthetic, or granite aggregates instead of marble to provide brilliant colors or chemical resistance. The best “thin-set” system.

Sand cushion terrazzo

A cement matrix topping underbed with wire reinforcing, isolation sheet, and sand layer system for interior floor use. This is the best cement system.

Bonded terrazzo

A cement matrix and underbed system for interior and exterior areas where conditions require 1.25″ to 1.75″ inches of recessed depth to be filled in addition to the .5″ terrazzo topping.

Monolithic terrazzo

This 1/2″ thick cement matrix veneer placed upon a provided concrete slab is dependent on the concrete quality for flatness and crack prevention. On grade or below grade only.

Polyacrylate terrazzo

A nominal 3/8″ thick polymer modified cement matrix veneer placed upon a provided level concrete slab. Polymer provides strength to allow for thinner applications of cementitious systems.

Rustic terrazzo

Terrazzo with a non-ground, textured surface, for exterior use. This system is available with Bonded and Monolithic Terrazzo.
