Here is the Stone and
Marble inspection SUPER SERIES!
Three schools and instructors have teamed up to create this special opportunity for stone inspectors ...
and those who want to become stone inspectors!
Everything you need
to become an IICRC Certified
Marble and Stone Inspector
is being presented in ONE place.

Marble and Stone Inspection
All in Las Vegas, Nevada.
This effort brings together three different schools to present the
Marble and Stone inspection course along with its two prerequisites, in the same place, at the same time, making a kind of Stone Super Course in one place. Bob Merkt, Libby Longstreth (from SST) and Fred Hueston (from NTC) have teamed up together to make it possible to take the Substrate class, the Floor Cleaning Technician’s class and the Stone and
Marble Inspection Certification class in one place without scrambling all over the country.
Earn IICRC certification in all three classes.
You will have a chance to earn 3 certifications and meet the prerequisite requirements for ALL floor covering inspection classes.
Even better... the series will be held in Las Vegas, Nevada this November 2005.
Las Vegas is one of the easiest and most comfortable places for seminars.
The substrate class and the
marble and stone inspection class will be held next to a stone yard to provide first hand examples of stone,
marble and substrate issues.
Why take the Stone and
Marble Inspection Certification class? As many of you know, the use of stone flooring in the US has increased dramatically over the past several years. Unfortunately, there are many installers that do not know how to properly install stone flooring. With this, comes an increase in the number of failures. There are very few inspectors in the world that are qualified to determine why these installations fail. Now you can be one of them. The best inspectors are those who have been working in the industry for a long time and are ready to convert that experience to expertise.

The
marble and stone inspection certification covers all aspects of
marble and stone such as
limestone, granite, terrazzo, slate, onyx and quartzite and their use in flooring and other applications. This includes stone restoration, fabrication,
polishing, burnishing and repairing. As well as how to evaluate installations, understand crack propagation, and troubleshoot failures and problem solving. Problems such as efflorescence, subfluoresence and lippage are covered. The use and choice of
grout, mastic,
epoxy, slip membranes, crack suppressors and support and underlayment systems are included. This class or course is approved for certification; certification is necessary to becoming a third party inspector or expert witness.
What is in the Substrate Class? The substrate class is a prerequisite for all inspection classes. It covers problems with concrete, wood, adhesives and leveling compounds under wood, ceramic, stone,
marble, laminate, resilient, carpet and
epoxy floors. This is a very intense class. These are complicated problems and plaque many installers and consumers. This class helps you develop an intuitive understanding of how all these things work together (or not) and affect various floorcoverings.
Problems covered include ... Moisture, Movement, Contamination, Alkalinity (pH), Fasteners, Maintenance, Manufacturing, Deflection, Level and Flatness, Adhesives, Patching Compounds and Concrete Sealers and concrete sealing.
The substrate and subfloor course includes topics necessary to becoming a third party inspector and expert witness for problems involving moisture problems in concrete, moisture problems in wood, patch materials, self-leveling compounds, and adhesives. Students from this course often develop consulting practices working with builders, architects, facility managers, as well as retailers and manufacturers.
Moisture detection and control and moisture problems are the focus of a large part of the class. The use of moisture meters including Protimeter, Tramex and Wagner in diagnosing and preventing problems is included. Instructions on ASTM standards and ASTM tests for understanding concrete problems including concrete vapor emission such as the calcium chloride test, tests using relative humidity in the slab and on top, pH testing and preparation of concrete for vinyl, wood, stone and other coverings are part of the course. Evaluation of cracks and cracking, slab curling, flatness, level, finish, drying, water-to-cement ratio, types of Portland cement, admixtures, interpreting petrography and other lab tests are in the concrete part of the course. Understanding underlayments and substrates including adhesives, cementitious products, self-leveling compounds, patch, plywood, particle board and name brand plywoods such as Multiply, Ultraply, are in the wood section. Diagnosing water damage, cupping, crowning, ripples, delamination, splitting, popping, cracks and cracking, gaps and gapping are covered. Understanding drying, evaporation and moisture control is a central theme. Set up time, open time working time, adhesive tests and failures in latex, acrylic, urethane and
epoxy based adhesives is covered.

 | | Marble | MARBLE: CHARACTERISTICS
This standard includes general information on the characteristics
and common uses of marble and identifies typical problems
associated with the material.
INTRODUCTION
Marble is an extremely hard, metamorphic stone composed of calcite
(CaCO3). It is formed as a result of the recrystallization of
limestone under the intense pressure and heat of geologic
processes. The effect of this process is the creation of a stone
with a very tight crystalline structure and small but definite
porosity. Because of its structure, marble can take a very high
polish and is a very popular decorative stone for architectural and
sculptural uses. The limited porosity of marble, especially
polished marble, makes it less vulnerable to the leaching effects
of water. Calcium carbonate, however, of which marble is composed,
is highly susceptible to attack by acidic agents. Marble is
readily dissolved by acids, even very dilute acids, however the
actual results of acidic exposure will vary with the nature of the
acid. Chlorides, nitrates, sulfates and other chemical compounds
react differently with marble and produce various by-products,
which have a wide range of solubility and impact on the durability
of marble. For this reason, it is always important to determine
the exact type of pollutants causing marble deterioration.
Marble itself can be of two types, one composed of calcite and the
other of dolomite. Dolomitic marble is much more resistant to acid
attack than calcite marble. The color of marble ranges from the
brilliant white of calcite to black, including blue-gray, red,
yellow and green, depending upon the mineral composition.
TYPICAL USES
Marble has many decorative and structural uses. It is used for
outdoor sculpture as well as for sculpture bases; in architecture
it is used in exterior walls and veneers, flooring, decorative
features, stairways and walkways. The way in which the stone is
used may be a factor in limiting or controlling the severity of
exposure. The use or function of the marble may also affect the
feasibility of applying certain treatments, but type of use is not
the primary factor in the major types of deterioration and damage
to which marble is susceptible. | |  |
