Deflection Limitations By Dale Kempster

Deflection Limitations
By Dale Kempster

The TTMAC (Terrazzo, Tile and Marble Association of Canada) released the completely revised 1997 "Specifications Guide 09300" which succeeds the 1989 edition.

In the new "Tile Installation Manual" the reader will find several references to ".... deflection under both dead and live loads does not exceed 1/360 of span." This reference can be found in details; 310F-98, 311F-98, 312F-98, 313F-98 and others. For many individuals this criterion of deflection may not be easily understood; both for the calculation and the actual ramifications for the installation in question.

First, a definition of deflection should be made; "A variation in position or shape of a structure or structural element due to effects of loads or volume change, usually measured as a linear deviation from an established plane rather than an angular variation". In other words, when a load is applied to a surface such as a plywood floor, that floor will often bend downwards in relation to the amount of weight applied and the structural capability of the plywood and the support ( i.e. joists) underneath.

It should be noted that the deflection is measurable both as the length of the span, as well as between joists, in the case of a residential application. In actual practice, what this means to the installer is that they have to know if the sub-floor will be able to support the tile and not exceed the deflection criterion of L/360.

In practical terms this means in a residential application with joists 16" o.c. (400 mm) the maximum deflection that can be allowed when using L/360 is 16/360 which equals 1/25"= .04"or (1 mm). Now how does this relate to a single layer of plywood sub-floor. When looking at the span tables published by the American Plywood Association, it will be found that a single layer of plywood 19/32" (15 mm) on joists spaced at 16" o.c.(400 mm) the maximum amount of weight that can be applied is 368 lbs (167 Kg) before the deflection succeeds L/360 (remember 1/25" or 1 mm)

Now, this may seem like a lot of weight, but this is a uniform load distributed over a wide area that is supported by the joists. If a concentrated load is applied between the joists using a 3"(75 mm) wide disk with 200 lbs (91 kg) applied to the same piece of plywood, the plywood can deflect, up to approximately .078" = 1/12.5" or 2mm. This calculation indicates that the single layer of plywood can have approximately twice the deflection acceptable for the installation of tile. In real terms, a concentrated weight of 200 lbs (91 kg) over a 3" (75 mm) wide area, is not all that difficult to attain in a situation such as a fridge or a stove being brought across a floor on a dolly.

With all of this being said, it can now be understood where the recommendation for two layers of plywood 5/8" (16 mm) thick or the use of other underlayments, is required by the TTMAC manual, Detail 313 F-98. Other underlayments such as ½" 13 (mm) cementitious backer board, or a pre-formed sheet applied membrane such as Schluter Systems, Ditra Matting can be considered.

Another consideration as well, is post-tensioned and pre-stressed concrete are often engineered with only L/240 deflection criterion. This means a slab 30 ft long, supported only at the ends, (L/ 360 = 360/360) could have deflection up to 1 " (25 mm). See TTMAC Detail 309F-98 for recommendations on installation over pre-cast concrete systems.

To give more food for thought, recently the Marble Institute of America has increased the deflection criterion to L/720, which is double that of tile. It is with all this in mind, that one should make sure that they are well acquainted with the new manual and its practices. Installation techniques and systems should be evaluated and be guaranteed to respect the L/360 criterion.

Re-discover Terrazzo By Tony Torriano

Re-discover Terrazzo
By Tony Torriano

Several hundred years ago in Venice, Italy a flooring system was created that has withstood the test of time and is still in use today. Terrazzo, from the Italian word terrace, was discovered by Venetian workers who found another use for discarded marble remnants created from odd size pieces of custom marble fabrications. It was recognized as a craft in 1579 by the Supreme Institution of the Venetian Republic. Prior to that time it was considered art and people practicing this were part of a minor branch of the art of the "mureri". In that year the "Mariegola dei Terrazeri" was drawn up that contained a list of apprentices or persons qualified for the construction of terrazzo floors. As a form of art, terrazzo was used in stately buildings from numerous palaces across Europe for Kings and Princesses to the Vatican and during the late 1700's the craft was brought to North America by skilled European immigrants.

 

Technological advancements in both installation techniques and range of available aggregates have impacted terrazzo, but the beauty, elegance and durability still exists today. From these roots of antiquity, today terrazzo is considered a contemporary flooring choice for use in buildings of our time. Over the past few years the appearance of terrazzo has been updated with new colors, natural aggregate, glass aggregate and the addition of metal particles or components. Combined with the improvements in the installation process and new equipment for grinding, terrazzo has experienced a revival as a choice floor system for heavy commercial areas or to create special effects in almost any application.

 

Terrazzo types

Although terrazzo offers the same general appearance the system may in fact be different beyond what you can see. There are several types of terrazzo systems that are first categorized by the binder type or paste that holds aggregates together like cement, acrylic (polyacrylate) or epoxy. Within the cement category, there are varying systems that have different overall thickness ranging from 13 mm to 75 mm (1/2" to 3") and are defined by the under bed layer. Each system offers benefits and functions that may be required for different construction methods. These systems include: Floating, Bonded, Epoxy bonded, Semi-Venetian, Venetian and Rustic.

During the 1960's the introduction of epoxy and acrylic binder compounds led to the development of thin-set terrazzo with thicknesses ranging from 6 mm to 10 mm (1/4" to 3/8"). These systems are lightweight, easier and faster to install and because of their thin profile they are ideally suited for renovation or rehabilitation work. For new construction, other finishes such as tile or carpet can easily be placed adjacent without the need to depress the concrete base slab. Advancements in polymer resin technology resulted in these systems being solvent free with virtually no odor, therefore, much more user friendly than the original. Over the last 7 years these systems have seen a significant increase in usage in Canada and throughout the United States.

Colors and aggregates

The binder that holds all aggregate particles together can be pigmented to almost any color and with the ever increasing use of epoxy as the binder, the spectrum of color and accuracy is unlimited. Natures' pallet of color is available from marble aggregates that are sourced within North America or Europe. Other aggregates like granite or washed, screened and graded stones can also be incorporated into terrazzo. Colored or recycled glass can be added to terrazzo in varying proportions or can be used exclusively. The use of glass allows the designer to incorporate unique or bold colors that are not available with marble aggregate colors for accents or special effects. Crushed sheet mirror or manufactured mirror particles that are available in different colors may be used to create sparkle or depth to terrazzo. Metal shapes, letters, or filings can also be incorporated into terrazzo for additional effects. The combination of new and recycled materials allows for virtually any design, pattern or image that is limited only by the imagination.

 

Advancements

Terrazzo has undergone many changes since its discovery, from installation techniques, to types of strips used. Divider strips originally consisted of wood that was used for shrinkage control that were later removed and filled with a mortar and finer marble chips. This method was later replaced with the placement of 19mm(3/4") x 19mm(3/4") marble strips that remained in the terrazzo surface. During the 1920's metal divider strips became available and continue to be used today with many different types of thickness and metal choices like zinc, aluminum or brass. Plastic strips were introduced through the mid seventies and offer a choice of color to complement the overall design.

 

By far one of the greatest improvements has occurred in the grinding procedure. From a manual process using a wooden pole with an abrasive stone attached to one end, referred to as a "Galera" this process was mechanized during 1924 to included rotary abrasive stones and plenty of water. Within the last five years this process has been significantly improved with the use of diamond abrasive stones in a dry process. This advancement has had considerable impact because it has greatly reduced the time required for grinding. Furthermore, the "pacerina" or residual slop has been eliminated and dust particles generated from grinding are captured with high powered vacuum units with efficient filters. Although wet grinding may still be necessary for polishing, the time saving and residual slop has been dramatically reduced.

 

The floating terrazzo system that ranges up to 75 mm (3") is designed to prevent or suppress the transmission of cracks that may form in the concrete base slab. This crack suppression concept has been adopted by thin-set epoxy type systems and has recently led to the development of anti-fracture membranes. These liquid applied membranes suppress the transmission of cracks that may occur in concrete and are directly bonded to the concrete base slab prior to the installation of an epoxy terrazzo system.

 

Maintenance and Life Cycle

Terrazzo has always been valued for its durability and subtle beauty. From its ancient beginnings, terrazzo has been used for floors in commercial buildings, hospitals, offices, churches, and airports and was considered the flooring material of choice in the commercial buildings industry of the 1950's and early 1960's. Independent studies have shown that when initial cost, replacement and maintenance costs are considered over a period of ten years the cost of terrazzo is less than most other floor finishes. When the same criteria is looked at over a 40 year period, the cost of terrazzo is significantly less than most other floor finishes.

 

Terrazzo, the floor that was invented centuries ago and walked upon by everyone has been updated in appearance and new technologies have been applied to it, so that it is faster and easier to install and appeal to current design trends. It is being used on many projects from small areas to create special effects to large mega projects like the new Terminal Building at Pearson International Airport. With the recent developments, color options and aggregate choices, there are more applications available for terrazzo than ever before.

Doug Dickinson Warranties

Extended Warranties for Ceramic Tile Installations

By Doug Dickinson,
Executive Director, TTMAC

We live in a growing value based society and quality issues are at the forefront of our purchases. Statistics show that consumers base their purchase decisions on three main issues: Price, Quality and Replacement. Is it within the budget, what quality concessions are to be considered if any, to bring it within budget and when will it need to be replaced or repaired?

Our industry, whether it is in the commercial or residential sector is no different. In the housing market, ceramic tile not so long ago was an upgrade in most homes. Builders realized purchasers understood the inherent value that ceramic tile added to their homes and by making ceramic tile a standard in most homes, purchasers would have an easier decision to make. Therefore, as usage increases so too should our responsibility to provide a comprehensive installation. As individuals, we would ensure that our own homes were to have all the provisions in place for a long lasting installation......

Budget constraints on projects are a fact of life; however health and safety issues should never be compromised. Health and Safety are not terms often associated with tub and shower installations. It is with increasing regularity that due to the breakdown of gypsum based products when exposed to moisture that mould rears its dangerous head. Mould is not a new phenomenon, but has come to the forefront of the media as a major health issue. Our schools, government buildings and various other structures are being vigorously inspected for its presence. Prolonged exposure to mould spore has proven to contribute to respiratory health problems. Costly renovations are being carried out to remove mould affected areas. As pointed out to me by a colleague, from a liability standpoint "mould is gold". Liability and litigation also enter the equation. Failure to properly ensure that all steps are taken to prevent such mould and other health hazards can result in costly lawsuits. Similarly the installation of standard drywall backer board alone in a wet environment is not an acceptable practice. Installations on bath tub/wall using a thin-set method should be installed according to Detail 306W-2002 of the TTMAC Specification Guide 9300 Tile Installation Manual. Many retrofits could be avoided if the installation were carried out according to this detail. It is not in our industry's best interest nor our client's to install contrary to these guidelines. If "necessity is the mother of invention", the resurgence of vinyl tub and shower inserts are of our own doing. Although they do have their place within the market, many hotels and builders have opted for them due to mould and mildew issues. Insisting on applying proven installation and maintenance techniques in tub and shower areas would for the most part eliminate these concerns.

It would be difficult to find someone who would not want to have their shower and tub enclosure last until they wanted a change for esthetic reasons as opposed to structural or health reasons. Cost of an installation carried out with the appropriate components and systems is far less expensive than the remedial work and the inevitable removal and reinstallation of the correct materials, not to mention lost worker days as a result of illness due to mould. Warranty; this becomes an inherent part of the project because the costly "call-back factor" has been greatly reduced.

Warranties are a large part of our society. We insist on warranties on all of our purchases large or small. By installing tile incorporating a waterproof membrane and or cementitious backer unit (CBU) as outlined in section 306W-2002 of the TTMAC Specification Guide 9300 Tile Installation Manual you are providing a proven system that does not provide an environment conducive to mould growth, therein lays the warranty. This warranty not only is provided to the end-user but also to the tile contractor in that remedial work for system failures has been greatly reduced.

Warranties are a tool for which you are better able to market your product and /or service.

Don't try and reinvent the wheel - perfect it!

A MESSAGE FROM THE PRESIDENT By Dennis Edissi

A MESSAGE FROM THE PRESIDENT
By Dennis Edissi

The first Terrazzo, Tile and Marble Association of Canada convention I attended was in Ottawa in 1974. The president at that time was Mr. John Woods. I was very impressed with this convention in general. The itinerary was well planned and informative; the activities were very interesting; and the aims and objectives of the mission statement of the Association were realistic and achievable. A lot of water has passed under the bridge since that time. This water represents a lot of very hard work by many very dedicated members and staff - all for the absolute benefit of our Association and our industry. From the day of its inception in 1944, the Terrazzo, Tile and Marble Association of Canada has continuously adapted new ideas and programs to improve the operation of our Association. I can assure you that this progress will never stop. Tile, marble and terrazzo have been manufactured for hundreds of years. Originally, pure clay was dredged from streams and riverbeds, cleaned from rocks and debris, formed into shape, and left in the sun to harden. We have come a long way since then; however, the basic concept of tile has not changed. Major terrazzo installations completed one hundred years ago, still look great today. Granite cladding installed centuries ago, still maintain their luster and durability. There are few products manufactured today that will outlast the beauty and endurance of terrazzo and tile. With the modern technology that is available, you can be assured that even more terrazzo and tile will be specified in the very near future. Our hard surface industry provides a truly everlasting and beautiful product that is extensively used on many major construction sites internationally.

I still recall the wonderful and informative speech by our keynote speaker Mr. Eberhard H. Zeidler, Senior Partner with Zeidler Roberts Partnership, one of North America's leading architectural firms. During his address at our National Convention in Toronto in 1999, he mentioned how pleased and honoured he was to be invited to speak at our convention. He made it categorically clear that second to the design of the structure, the many various types of hard surface materials he incorporates in his designs definitely contribute to the beautiful finishing touches to each building. He encouraged all architects and designers to specify more hard surface products to ensure everlasting and beautiful results.

I am very proud to be part of the tile and marble industry. For over 40 years I have enjoyed the benefits of the many challenges of this trade. I sincerely believe that my first toys were tiles. I am very fortunate to have two highly respected and very qualified mentors, as I was growing up in this industry, who taught me the"tricks of the trade." The first was my late father, Dante Edissi and the second, Douglas Del Net, my uncle, Principal of Centura, London. The integrity, knowledge, experience and appreciation of the product and trade I learned from both, formed the foundation of my career.

It was an easy decision for me to accept the position as President of this great Association especially with a very supportive team of Directors and staff at my side. As I glanced around the table at our last Board of Directors meeting, I felt very confident with the experience, knowledge and dedication that each and every director contributes to this committee. Our directors represent contractors and suppliers who share their valuable time for the benefit of each member and for our Association. I would like to recognize and take this opportunity to thank the many members and volunteers who so graciously share their time for our Association.

We have a great Association supported by many enthusiastic and dedicated members. Our staff is comprised of experienced and hard-working individuals who sincerely believe in the aims and objectives of our Association. The Terrazzo, Tile and Marble Association of Canada is recognized as the foremost authority of the hard surface industry and will continue to grow in strength to serve our membership and our industry for many years. We want to provide the highest standard of service to our members and to our industry. I strongly encourage all members to get involved with our Association and to solicit other qualified potential companies to join the Terrazzo, Tile And Marble Association of Canada. An Association is only as strong as its membership. We must all work together, and together, we will succeed.

We also thank the many consultants that include architects, designers and specifiers for supporting TTMAC members and hard surface products.

In closing, I would like to leave you with this thought, "The block of granite which was an obstacle in the path of the weak, becomes a stepping stone in the path of the strong."

Sincerely,
Dennis Edissi,
President

Dennis Edissi is the current TTMAC President. He started his career in 1960 with his father Dante Edissi at Twin City Tile Co. Ltd. in Kitchener of which he is President. Dennis is a very dedicated and hard working volunteer who has greatly contributed toward the success and growth of many organizations. As President of the Terrazzo, Tile and Marble Association of Canada, and with his sincere dedication and loyalty to our industry, Dennis will continue to be an asset to our Association.
