Before you can use a ceramic tile or stone floor, you need to know if the subfloor is actually with the capacity of supporting tile. Simply put, tile can be a durable, zero-maintenance, beautiful floor choice...if it's on a good substrate. Or it could be an expensive mistake that cracks, breaks and requires multiple fixes that may never work if the subfloor is not prepared correctly. What elements do you need to appear out for to choose if tile is right for your project, and what steps can be taken to insure a trouble free installation?

For tile to be successful, it requires rigid support, with hardly any tolerance for motion. The even more rigid the substrate, the better chance the tile has of remaining crack free throughout its life. Most problems with tile floors over wood come from excessive 'bounciness' of the substrate. Carpet are designed for some bending, vinyl tile can flex and bend a little bit, hardwood flooring can bend a touch too, but if tile or stone is subjected to forces that force in 2 different directions at once, it doesn't learn how to bend. Rather, it cracks, 1st in the grout and then in the body of the tile. Customers who've just paid thousands for a tile floor do not find these cracks interesting, to say the least.

In residential settings, the most typical substrates [surfaces to be tiled] for flooring are wood and cement. In this post we'll deal with cope with solid wood subfloors. In new building, it's possible to start to see the framework of the subfloor and joists and generally talk to the carpenters who built them or the contractor responsible for the task if there are any queries. In remodeling, however, occasionally one can just guess who set up the ground and how strong it is. Probably it's as solid as a battleship, or possibly it's about to fall to the basement. If a house owner is attempting to set up the floor himself, she or he may wonder how to know if the subfloor can be solid enough. Let's focus on the technical and then translate it to the everyday method to tell.

There are formulas used in the industry to determine if the subfloor has excessive 'deflection' [bounciness, insufficient rigidity]. The most cited one may be the Tile Council of North America standard for deflection, which is stated as L/360 as the very least, before tile underlayment is installed. L/360 means that the floor shouldn't bend under weight a lot more than the distance (expressed in ins) of the unsupported span divided by 360. For instance, if the period between supports runs for 20 foot 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" may be the maximum amount of movement the center of the span should be allowed to move.

Fine, but how do you know if your floor meets the L/360 standard? We face this in the field on a regular basis, however in remodeling, there's not necessarily a clear response. There are released tables for calculating deflection, (including an extremely cool online calculator at http://www.johnbridge.com/vbulletin/deflecto.pl ) but they assume you have full knowledge of how the ground was built. In order to utilize the engineering tables, you'd need to know what lengths aside the joists are, the space of the unsupported period, how heavy the joists are, which kind of wood and in what condition the timber is in, as well as how thick the plywood is normally, if any. Realistically, if all this flooring is hidden by completed ceilings below and covered over by old flooring layers above, educated guessing will take center stage. The next questions help to determine floor stiffness using good sense guidelines:

1. What floor covering was on to the floor before? If it had ceramic tile or stone, and the ground received reasonable visitors for years without cracking or damaged grout, it's a pretty good wager that the subfloor is certainly up to the job. If it had been vinyl, carpeting or hardwood, we are still in the dark.

2. Does the ground feel bouncy? If therefore, it really is. Trust your instincts. It's not prepared for tile. A well developed subfloor feels extremely stiff underfoot. Squeaking may also be a poor sign, but it may also solvable by screwing down the planks or plywood better into the joists.

3. How thick may be the subfloor and the facts made of? In new construction, ¾ in . plywood or Oriented Strand Panel is a standard subfloor more than joists that are 16 inches on center apart. We find that is almost never more than enough to meet the deflection standards in most homes. Other times there is aged plank flooring beneath a coating of plywood. That is a wild cards, since the engineering tables usually don't include the value for planks within their calculation, but common sense says it will add some stiffness.

4. How tough is the tile to be installed? Fairly thick quarry tiles, for instance, may be rated for durable commercial applications, although they are often installed in homes. Because they are thicker than normal tiles and in a position to withstand heavy visitors, they might be less susceptible to cracking than a sensitive, slimmer tile. For example, natural stone such as marble and granite are on the additional end of the spectrum - they crack even less difficult than ceramic tile and should not be used in settings where any extra deflection is possible. Intuition may tell you he is stronger than ceramic, but in truth they are more brittle and susceptible to cracking. They need twice as rigid a floor as ceramic.

5. What condition does the wood look like in? Even if the amount of solid wood support seems adequate based on the tables, if it seems to have been drinking water damaged, if sections of it look moldy or corroded due to rot or decay, it isn't doing its job. Options include changing or reinforcing it, but not just ignoring it. Also, offers it been slice into in various spots, like a plumber cutting sections of the joists for positioning pipes? Most of these problems can make the wood much less effective.

6. What's the house owner's risk tolerance? Will he/she desire http://stephenpczt747.raidersfanteamshop.com/the-biggest-trends-in-flooring-store-augusta-ga-we-ve-seen-this-year to be rock solid certain of the balance of the ground? Even if that means spending extra money and/or period to reinforce the ground, and accepting a ground that may sit higher than surrounding flooring? Or is some threat of failure acceptable if the floor is not created to the righteous criteria of the TCNA? Occasionally the extra effort isn't worth the cost to the house owner, who ought to be completely informed on all options. Contractors who install flooring shouldn't assume that clients don't care enough to resolve the problem: within the last yr we've had two customers who spend thousands of extra dollars to reinforce subfloors in a kitchen and laundry area when we explained that their flooring were as well unstable for tile. They actually wanted tile, and had been ready to make the subfloor ready for this, even if it price more.

7. Is there an unfinished ceiling below to research and measure the range between joists and the health of the wood below and how long the unsupported span is? A few minutes in the basement with a torch and tape measure can let you know if you have successful (solid and deep joists, spaced closely together, in good condition, with a narrow period), or a loser (thin and http://edition.cnn.com/search/?text=Augusta Georgia shallow joists, irregularly spaced or spaced considerably apart, in poor condition, with an extended span).

8. Can you cut into the layers on best to obtain a cross portion of the existing floor? If there is a heating system grate that you can remove, that may display the layers the floor is composed of. Exactly what will end up being reassuring to see can be a thick layer, ideally over 1 ½ inches thick of plywood. Additionally, with the property owner's permission, we sometimes cut directly into it to check on what it's composed of.

If a subfloor displays excessive deflection, it can usually be remedied by installing more plywood on top of it before tile is laid, and by reinforcing the joists from below. While it may make the floor higher than before, think of it as sort of 'insurance policy' against flooring failure.

Contractors who all address these problems with their customers beforehand are just doing the client a favor. The industry all together benefits when tile installations are carried out correctly and extreme deflection is avoided initially.
