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.

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 con-junction 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 increase cost.

Nominal 1/4" or 3/8" Epoxy Terrazzo topping. 0-1 chip sizes opt. #2 chip for 3/8"

3-4 lbs PSF

All these systems adhere to the concrete and require dividers to be placed precisely above any concrete joints. To prevent the concrete from cracking and therefore the terrazzo, ACI 302.1 R.89 Concrete Joint Placement must be followed. Some of these requirements include: Concrete joints should occur a maximum of three times in feet the depth of the concrete in inches. (Example: A 4 inch slab should have concrete joints at a maximum spacing of 12 feet.) Concrete joints should run off all corridor intersections and corners.
They should not be spaced more than 1-1/2 times the width of the concrete pour.
(Example: A 6 foot wide corridor should have
concrete joints at a maximum of 9 feet.)

In addition other dividers can be set to separate
colors or as an accent themselves. In these systems the dividers not located over concrete joints are strictly decorative. They do not function as leveling devices or crack preventers.

Dividers vary in width from 18 gauge to
1/2 inch. 16 gauge or
1/8 inch are standards. Zinc is standard but brass and colored plastic are readily available.

Polyacrylate

$$

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

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.

Nominal 3/8"
Polyacrylate with Terrazzo topping.
Chip sizes 0, 1 & 2.

4-1/2 lbs. PSF.

This 1/2 inch 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.

Fast installation and the most economical price make it ideal where time and budget are critical but where the beauty, low maintenance and the performance of terrazzo is desired.

1/2" Terrazzo
topping.

5-7 lbs. PSF.

A cement matrix and underbed system for
interior and exterior areas where conditions
require 1-1/4 inches to 1-3/4 inches of recessed
depth to be filled in addition to the1/2 inch terrazzo topping.

With the sand-cement underbed it has less dependence on the concrete slab for flatness when compared to monolithic.

1-3/4 " to 2-1/4"
including 1/2"
Terrazzo topping.

18-22 lbs. PSF.

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

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.

2-1/2" to 3" including a 1/2" Terrazzo topping.

25-30 lbs. PSF.

The position of divider strips is essential to
performance, serving a dual function: a control
for anticipated contraction and an aesthetic enhancement in separating colors. 5 feet or less on centers. Architects should design structural inset expansion plates between areas where major movement is anticipated.

Structural

$$$

For large areas over a graded compacted base. Involves 4" of 3,500 PSI underbed concrete plus
1/2" Terrazzo topping.

Single contract control: One contractor places
both the concrete slab and the finished ter-razzo
surface.

4-1/2" to 6", including a 1/2" Terrazzo
topping.

Approx.
60 lbs. PSF.

Divider strips are deeper than usual: 1-1/2 inch
to 2 inches inserted into the underbed 8 feet to 10 feet on centers. Control strips are provided on column lines.

Rustic
$ varies with system

Terrazzo with a non-ground, textured surface, for exterior use. This system is available
with Sand Cushion, Bonded, Structural and
Monolithic or any cement system.

Infinitely variable textures, colors and patterns may be created in a weather-resistant, skid-resistant deck surface.

1/2" to 6" including a
1/2" Terrazzo topping.

Dependent on system selected.

Temporary wood strips are used, then replaced by a pourable sealant inserted into the joint.

Prefabricated custom units for steps, bases,
planters, benches, wall panels, etc.

Unlimited uses.
