Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

Key Resin Co. History• Founded in 1993, by Robert Cain, President.• Bob Cain has been the co-chairman of the National Terrazzo and Mosaic Association’s (NTMA) Technical Committee since the mid 1970’s.• Key Resin offers:

– Epoxy Terrazzo Flooring– Resinous Flooring Systems– Moisture Vapor Control Primer, Crack Isolation Membrane– Full Range of Coatings for Concrete Floors and Walls

The purpose of this presentation is to provide general information which will be helpful in specifying terrazzo. The participants will gain an understanding of the various terrazzo systems and how it can be utilized in a variety of design applications.

Course Description

Learning ObjectivesUpon completion, you will be able to:

Explain WHAT Terrazzo is

You will know the HISTORY of Terrazzo

See WHY to specify Terrazzo

How terrazzo can contribute to project sustainability

Explain the different TYPES of Terrazzo

See that the DESIGN POSSIBILITIES are endless

What is Terrazzo

A “poured in place” mortar of portland cement or epoxy resin mixed with chips of marble, glass or other aggregate.

Terrazzo flooring is poured, troweled, cured, ground and polished to a smooth surface to show the chips.

Design & Detail SpecificationsTerrazzo Strips

• Common materials:– White alloy of zinc, aluminum, brass and plastic are recommended– Stainless steel are not recommended as it causes problems when

grinding.

• Review the Expansion Joints and Control Joints in your floor. Do this with your flooring contractor!

• Honor all Expansion and Control Joints – Best Option!– Incorporate joints into the flooring design, if possible.– Specify areas in floor that may require buried control joints.

» Excessive concrete movement may cause cracks or heaving even with membrane treatment.

– Long corridor runs should allow for divider strips perpendicular to the corridor.

Surface Prep – New Concrete

Minimum 28 day cure on standard concrete

Perform moisture testing to confirm suitable levels

Remove all contaminants by chemical cleaning

Concrete Surface Preparation - Follow ICRI Guideline No. 03732

Mechanical bond is important - remove laitance & obtain a uniform surface texture (ICRI CSP #4-5)

Moisture Vapor Transmission

What is MVT?

Moisture Vapor Transmission (MVT) is the natural migration of moisture vapor

through sub-grade earth and building components.

Moisture Vapor Transmission

Epoxy Terrazzo

Moisture Vapor TransmissionPossible Sources of Moisture

• Slabs-on-Grade with No Effective Vapor Barrier

• Elevated Slabs using Pan-Type Construction

• Lightweight Concrete

Occurs when a source of moisture and a non-breathing system on the surface are

present.

LEEDingTerrazzo

• Leadership in Energy and Environmental Design (LEED) – LEED 2009 for Commercial Interiors

• To earn certification, the project team must satisfy a criteria of seven prerequisites and earn:

• 40-49 points for Basic certification• 50-59 points for Silver certification• 60-79 points for Gold certification• 80+ points for Platinum certification

LEEDing Terrazzo

• Use of terrazzo may contribute to LEED Credits in the following areas:

LEEDing Terrazzo

• Use materials with recycled content• 100% recycled glass is not recommendedMR Credit 4

• Use of regional materials (500 mile radius)MR Credit 5

• Building reuse credit for reusing existing terrazzo floorsMR Credit 1.2

• Subcontractor working with the GC to reduce construction wasteMR Credit 2

• Low-Emitting Materials (Flooring Systems) • Epoxy terrazzo uses 100% solids, zero VOC resins resulting in no

air contaminantsCredit 4.3

• Innovation Design Credit (ID Credit 1) - Creative or innovative design or material application

LEED – Innovation Design Credit

• Epoxy Terrazzo has the lowest life cycle cost when compared to other flooring systems.
