Tile Underlayment Positioning

Positioning Underlayment to Prevent Tile & Grout Cracks by Frank Woeste, P.E. and Peter A. Nielsen

The 2003–2004 Tile Council of America’s (TCA) Handbook for Ceramic Tile Installation contains numerous details for a double layer wood floor system supporting ceramic tile. The thicknesses of the subfloor and tile underlayment are given in each case. Specific guidance on where to butt the underlayment end joints is not given for any detail. For example, for F142-03, the TCA Handbook states, “offset end and edge joints of the underlayment panels by at least two inches from the joints of subfloor panels; they should not coincide with framing below.” It further states, “underlayment fasteners should not penetrate joists below.” In the case of F150-03, the offsetting is not mentioned, but it does state, “underlayment fasteners should not penetrate joists below.” The same holds true for F155; however, it also states, “face grain of plywood should run perpendicular to trusses, I-joists, or sawn lumber for maximum stiffness.”

This is a review of the subject and I hope it helps people in the flooring industry in dealing with different types of slabs with control joints and cracks. Read More

Customer Relations for the Flooring Inspector

dollarsWe are all consumers and we all encounter products or services that do not meet our expectations. The consumer having a problem with their floor covering is no different from me or you. The flooring they paid good money for is not living up to their expectations.

When I first became involved in complaint handling, I thought I would see a lot of people trying to get something for nothing. The complete opposite has proven to be the case. In all the years I have been doing inspections less than a handful have met that ulterior motive. The overwhelming majority of unhappy consumers just want what they paid for. Read More
