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.
One of the most traditional flooring ideas to go for is using terracotta tiles. You can get a handcrafted look for your floors with this kind of tile. You can use it in the regular square shape or get ones in octagon shapes. etc. Put a picture on your floors with mosaic tiles. You can make a pattern or lay them out randomly for a unique design. Lastly. you`ve got glass tiles. These can be used as tile flooring ideas to give a quality finished look to any room.
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.
Does the floor feel bouncy? If so. it is. Trust your instincts. It`s not ready for tile. A well built subfloor feels very stiff underfoot. Squeaking can also be a bad sign. but it may also solvable by screwing down the planks or plywood better into the joists.
