Tile floor installation adds resale value to your home. because buyers know they are acquiring a house with an incredibly long-lasting floor. Potential buyers take notice of a well installed and designed tile floor. It makes a statement about how you have cared for your home. With its attractive style and impressive presentation. a good tile floor can add thousands of dollars in potential value.
Can you cut into the layers on top to get a cross section of the existing floor? If there is a heating grate that you can remove. that may show the layers the floor is composed of. What will be reassuring to see is a thick layer. ideally over 1 ½ inches thick of plywood. Alternatively. with the property owner`s permission. we sometimes cut in to it to check what it`s composed of.
There are formulas used in the industry to determine if the subfloor has excessive `deflection` [bounciness. lack of rigidity]. The most cited one is the Tile Council of North America standard for deflection. which is stated as L/360 as a minimum. before tile underlayment is installed. L/360 means that the floor should not bend under weight more than the length (expressed in inches) of the unsupported span divided by 360. For example. if the span between supports runs for 20 feet then the deflection should not be more than 2/3" between the center and the end. L=20 x 12" = 240". L/360 = 240"/360 or 2/3". So 2/3" is the maximum amount of movement the center of the span should be allowed to move.
In residential settings. the most common substrates [surfaces to be tiled] for flooring are wood and cement. In this article we`ll deal with deal with wood subfloors. In new construction. it`s often possible to see the structure of the subfloor and joists and usually communicate with the carpenters who built them or the contractor in charge of the project if there are any questions. In remodeling. however. sometimes one can only guess who installed the floor and how strong it is. Maybe it`s as strong as a battleship. or maybe it`s about to fall through to the basement. If a property owner is trying to install the floor himself. he or she may wonder how to know if the subfloor is strong enough. Let`s start with the technical and then translate it to the everyday way to tell.
