There Are Different Reasons Due To Which Tiles Can Become Loose

Posted On October 31st, 2016

For property owners, it is frustrating, but it doesn’t mean a complete retile. That is why Pro Tiling Melbourne handling latest techniques to overcome that. Floors can move up and down and expand at different rates. For instance, concrete, as opposed to tile, can move nearly twice the rate, and tiles can fluctuate in size. Tiles fluctuate in size due to Thermal Expansion- temperatures heating up and the effect is tile expanding. While this may not seem like much of a factor, it does effect the tiles over the life to the floor and cause trouble with the flooring.  Let’s look at some common problems.

No Expansion Joints

No expansion joints can cause tiles to pop off the floor and come loose. Expansion joints are included in the installation (or should be included during the installation). At least a 1/8 inch joint should be included along with all perimeters up against walls to allow for the home’s natural movement. The joint should be left open and covered by the baseboards. Also, needing joints include wide floor expenses for concrete expansion. Expansion joints need to be included in floors that are more than 20 feet in width/length and preferably caulked than grouted. Caulking will ensure the pressure from the Tile Expansion will not cause tiles to pop up.

Improper Thinset / Tile Combination

The right type of thin set mortar for the project is essential. For instance, heavy traffic areas will require more than a basic cement, sand and water mixture. If the tile was installed with a cheap, non-latex thin set, the bond would be limited. And, if the tiles are porcelain tiles, you likely won’t have a bond at all. The right inset is essential.


The subfloor requirement is essential to ensure that the surface is strong enough for Tile Installation in Melbourne. Deflection is known as up and down movement, and often present when the subfloor material used does not have sufficient thickness on the top of the floor joists. Also, proper spacing of the joints is necessary and will depend on the material type. Subfloor minimum is the installation of double layered, 1 1/8 inch thick, exterior grade plywood over floor joists that are spaced a maximum of 16 inches on center.

Improper Underlayment

Improper underlayment is another mistake during installation. For instance, wood is never acceptable when installing a tile floor. Concrete must be used or a fiber based underlayment of at least ¼ inch thickness. Mortaring down the underlayment to the subfloor is necessary with screws or nails each four to six inches of the floor surface.
