Terrazzo Information
EPOXY TERRAZZO
Description:
A nominal 1/4″ or 3/8″ thick resin matrix veneer placed upon a level concrete slab; Also can be specified with glass, synthetic, or granite aggregates in lieu of marble to provide brilliant colors or chemical resistance; The best “thin-set” system.
Advantages:
Unlimited matrix colors, color control, resiliency, chemical resistance and tensile-compressive strengths not found in cement based systems. Excellent for multi-colored patterns and designs. Light weight and flexibility make it ideal for multi-story use. It has the lowest maintenance cost due to non-absorbancy. In sanitary areas can be installed with minimal dividers providing seamless characteristics. When used in conjunction with a flexible membrane as a specified extra, it can absorb some horizontal concrete crack or control joint movement. It also has the quickest pour to grind installation time. Can also be used over properly installed and prepared plywood. Glass and other decorative aggregates increased costs.
Thickness:
Nominal 1/4″ or 3/8″ Epoxy Terrazzo topping. 0-1 chip sizes opt.#2 chip for 3/8″.
Weight:
3-4 lbs. PSF.
SANDCUSHION TERRAZZO
Description:
A cement matrix topping underbed with wire reinforcing, isolation sheet, and sand layer system for interior floor use. This is the best cement system.
Advantages:
Due to the underbed’s depth, wire mesh reinforcing, isolation sheeting and sand layer it will absorb minor substrate defects and prevent mirroring to the surface.
Thickness:
2.5″ to 3″ including a .5″ terrazzo topping.
Weight:
25-30 lbs. PSF.
BONDED TERRAZZO
Description:
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.
Advantages:
With sand-cement underbed it has less dependence on the concrete slab for flatness when compared to monolithic.
Thickness:
1.75″ to 2.25″ including .5″ terrazzo topping.
Weight:
18-22 lbs. PSF.
MONOLITHIC TERRAZZO
Description:
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.Advantages:
Fast installation and the most economical price make it ideal where time and budget are critical but where the beauty, low maintenance and the preformance of terrazzo is desired.
Thickness:
1/2″ Terrazzo topping
Weight:
5-7 lbs. PSF.
POLYACRYLATE TERRAZZO
Description:
A nominal 3/8″ think polymer modified cement matrix veneer placed upon a provided level concrete slab. Polymer provides strength to allow for thinner applications of cementitious systems.
Advantages:
Fast installation and moderate price range make it ideal to replace vinyl or carpet without depth transition difficulties; also good to use in areas subject to moisture vapor transmission where Epoxy terrazzo or other non-breathing floors will not adhere.
Thickness:
Nominal 3/8″ polyacrylate with terrazzo topping. Chip sizes 0,1 and 2.
Weight:
4.5 lbs. PSF.
RUSTIC TERRAZZO
Description:
Terrazzo with a non-ground, textured surface, for exterior use. This system is availablewith Bonded and Monolithic Terrazzo.
Advantages:
Infinitely variable textures, colors and patterns may be created in a weather-resistant, skid-resistant deck surface.
Thickness:
Bonded 1.75″ – 2″ including a .5″ terrazzo topping.
Monolithic .5″ terrazzo topping.
Weight:
Dependent on system selected.
