National Terrazzo & Mosaic Association, Inc.Terrazzo General Information
Terrazzo flooring has a long and rich history dating back over 1500 years. Terrazzo, from the Italian word for terraces, is one of the original recycled products created centuries ago by Venetian craftsmen utilizing the waste chips from marble slab processing. Today terrazzo flooring continues to provide the ultimate in durability and low maintenance, typically lasting the life of the building. Terrazzo is the best flooring solution for most building types from performance driven institutions such as schools, airports, and hospitals to high design driven markets of retail and commercial buildings.
Terrazzo is composed of a mix of aggregates embedded in cement or epoxy. Aggregates may consist of a combination of marble, granite or quartz, recycled glass, plastics, and other specialty materials and are embedded in pigmented cement or epoxy matched to the color desired. Because of its unlimited color palette, each terrazzo installation is unique and infinitely customizable.
Today's buildings demand environmentally friendly, sustainable finishes. As it has for centuries, terrazzo provides a flooring solution with low lifecycle costs, small environmental impact, and recycled content. Additionally, terrazzo does not support microbial growth. This helps to create a healthy indoor environment. Terrazzo may realistically contribute to five LEED credits.
The following is basic information about different terrazzo systems. Please contact the NTMA for additional information, technical questions, specifications, or color samples.
Epoxy (Thin Set) Terrazzo:1/4" or 3/8" thick resin terrazzo veneer placed upon a provided level concrete slab, this system creates the ideal floor for multi-story or ground levels. Ideal for both vertical and horizontal applications, this lightweight system offers a full range of colors. Both epoxy and polyester resist many types of chemical spills, making them perfect for labs, hospitals and manufacturing facilities.
Sand Cushion Terrazzo:This is the best available cement terrazzo system. This system is for interior floor use on lower and ground levels and multi-story buildings alike. The terrazzo is separated from the concrete substrate by an isolation membrane or fine layer of sand. Divorcing provides protection from minor substrate defects and prevents mirroring to the finished product.
Bonded Terrazzo:This cement system is ideal for interior and exterior areas where conditions require 1 3/4" to 2 1/4" of recessed depth to be filled. With an adjustable lesser thickness requirement, bonded terrazzo can be used for floors, bases, walls, or any vertical surface.
Rustic Terrazzo:This exterior application has a textured surface, and is available with sand cushion, bonded, structural and monolithic systems. Infinitely variable textures, colors, and patterns may be created in this weather-resistant, non-slip surface.
