Quality control - the best way to avoid ceramic and stone installation failures

Installation failures are the most detrimental occurrences in the ceramic tile and stone industries.  They leave the wrong impressions about products or services and they can be very time consuming and expensive to repair. 

 Will Rogers once said, "It takes a lifetime to build a good reputation, but you can lose it in a minute." That’s so true when a ceramic or stone installation fails. Thankfully it doesn’t occur frequently, but when it does everyone involved loses.  It doesn't matter whose fault it is, everyone pays one way or the other in money, time or reputation.  As an industry, it's in everyone's best interest to do whatever we can to avoid failures and perpetuate quality installations.

The best way to ensure quality installations is through a Project Quality Control Plan.  A Plan sets expectations and standards for a successful outcome. Not only can this help avoid a failure by ensuring the products are being installed correctly, but during the installation even untrained laborers are exposed to and learn proper methods and industry standards.

The majority of ceramic tile and stone failures are due to labor errors and occur because installation standards and product directions are not followed.  Ceramic tile and stone installers don't go to college or trade schools to learn their trade. Typically they learn on the job from more experienced installers that may have been installing tile the same way for 20 years. These “old-timers” may not be aware that the new generation of materials require new methods. They just figure the old way is the right way and teach the next generation of installers the same.

Architectural specifications contain standard sections with quality assurance and quality control specifications for products and installers and methods for each application. This section calls out the process necessary to verify the products are being used and installed correctly.  Unfortunately, instead of thoroughly customizing these sections each time for each project, architects often “cut and paste” this information from one project to another. The result is that quality assurance gets value engineered out of the job, and the quality control is left up to the installer to provide internal quality control; both of these scenarios contribute to failures due to the lack of information and controls.

A good architectural specification will require that ceramic tile and stone products be tested to verify they meet the industry standards for the intended use and that the installer has experience at performing similar type of work for the intended application.  It will require mock-ups to be constructed in advanced, per the specification, to be used as a quality control during the project. Then it will provide a detailed quality control plan to be implemented by a qualified third party inspector on behalf of the owner of the project.

At our company, Ceramic Tile and Stone Consultants (CTaSC), our quality control inspectors are seasoned journeymen or licensed installers who verify that the ceramic tile and stone products are being installed correctly and they teach installation methods and techniques to those who often have limited experience and limited supervision at their company. The result is that the installers are taught how to install correctly and supervised to make sure they follow the proper installations methods.  By the time an installer completes a project he has practiced and used the proper installation methods for so long and he is likely to use those techniques on future projects.
In short, a good quality control and quality assurance program is a win-win situation. It perpetuates quality work and avoids failures.  The customer gains a beautiful installation that will last for many years without problems as intended.  The installers, distributors and manufacturers get referrals based on a well executed job.  Everyone avoids the costly inconvenience of a failure that will cost each of them money, time and reputation!

How do you plan and control your installations? Are your expectations clearly spelled out, and your installers trained in the latest methods and materials?

Concrete Moisture Leading to Flooring Failures - Is this an Epidemic?

Sheet vinyl  lifting off concrete substrates that looks like blistered skin from a burn, wood flooring turning up at the edges, carpet tiles emitting foul odors from reactions with “wet” slabs.  All of these failures in floor covering occur daily around the country plaguing flooring contractors and end users.  Is this a flooring conspiracy or something more sinister?  Well, it’s not a conspiracy, nothing so colorful as that, and it’s not sinister unless you consider that moisture lurking in the substrates is skulking around waiting to pounce. What are the reasons for this outbreak of flooring failures?  Have adhesives changed?  Is flooring material different?  Hasn’t concrete been the same for years?  Why is this all happening now? Adhesives have changed from when solvent carriers were used but adhesives are actually better now.  Flooring products have changed with the onslaught of non-permeable backings which can trap moisture vapor emissions coming from concrete.  Concrete hasn’t

Intelligent merchandising in the floor covering showroom

Donato Pompo In a ceramic tile and stone showroom the two biggest challenges for customers are  visualizing how the tile or combination of tiles will look installed in the home and determining which tiles are suitable for their intended application. Figuring out how to address these two challenges should be a priority for every showroom. Along with that, conveying the features, benefits and limitations of the products is the next challenge. And perhaps the most important piece of the showroom puzzle, is to train sales people so they are knowledgeable and competent showroom consultants (I wrote about this previously on the blog in, How Training and E-learning Can Improve ROI ).   Years ago, when I was an importer and distributor with several showrooms I coined the term Intelligent Merchandising to represent the approach we developed to help our customers make selections and our sales people more effective in assisting our customers during the selection process. The challeng

Will Chinese Drywall VOC Issue Affect Flooring?

Chinese drywall shares commonalities with flooring, particularly as it relates to VOCs. If you’re new to the flooring industry you may be surprised to learn that last decade it was necessary for the Consumer Product Safety Commission (CPSC) and the Environmental Protection Agency (EPA) to anoint carpet as a safe product . The proclamation was due to flawed tests perpetrated against the carpet industry by Anderson Laboratories . But the issue isn’t dead if you search the Internet. There are still sites that support Anderson Labs. Even a "green" industry site writes “ A rash of alleged health problems with carpet have yet to be properly explained, suggesting that all carpets, and especially the less expensive synthetics, should be used with great caution .” The drywall industry is going through a similar experience. Two major differences: 1. They’ve pinpointed it to some drywall made in China. 2. It’s true and real, and no one is suggested it isn’t destroying homes and p
