Are cracked tiles a problem?
A cracked tile in a shower can cause problems that you don’t see.
Why is repairing cracked shower tiles important?
Recently we were asked to inspect a shower where the homeowner had found a couple of cracked tiles. The fault didn’t seem to be too serious on the surface. In fact, the owner told us that the tiles had been cracked for a couple of years and he’d been meaning to have the shower tile repaired.
The homeowner was quite right in saying that the cracked tiles didn’t seem like much of a problem on the surface. The damage seemed minor and the rest of the shower recess was in fair condition so replacing the tile in the shower was the furthest from his mind.
When we used thermal imaging to see what was happening below the tiles, it became clear that significant water damage was occurring below the surface. Water had been leaking through the cracked tile. In showers, where there is no visible damage, behind and under the tiles, you will find water is saturating the timber wall frame.
Cracked tiles, why do they occur?
There are a number of reasons why tiles crack and grout lines fail in showers and bathrooms, some are more obvious than others.
- Something heavy has been dropped onto the tile
If the crack is in a single tile, something striking the tile is the probable cause. If this is the case you may even notice a chip in the surface of the damaged tile. In such cases replacing a single tile taking care not to compromise the waterproofing may be the best solution for the shower floor tile repair. Alternatively, it may be timely to check the rest of the shower recess and if necessary service the shower recess by regrouting with waterproof high quality epoxy grouts and sealants.
- House movement
If cracks appear in a line across multiple broken tiles and/or grout joints are cracked, it’s probable that the home has experienced some settling or movement which is not uncommon in our Queensland climate. This is a more serious issue but one that is a routine fix for The Shower Dr.
To ensure the water integrity of a shower where there are cracked shower tiles and grout lines, we strip all of the grouts and silicone from your shower, test all tiles for integrity, remove and replace any existing tiles that may be damaged. We rectify any damage and seal your shower with Mapei premium-grade and chemical resistant grout. Most showers can be serviced in this way in just a day.
- The tiles were placed over improperly spaced joists and/or substandard flooring
In the case of tiles, the less deflection or movement the better. Timber joists and flooring are flexible while a tile is rigid, if you have flooring that flexes too much, it’s probable that damage and hairline cracks in tiles will occur.
Repairing cracked shower tiles, why it’s so important
The simple answer is that cracked bathroom tiles leak and compromise the waterproof integrity of your shower. It may appear on the surface that no damage is being done by a cracked tile and indeed, you may not notice water escaping from your shower for some time. However, water finds a way through even the smallest crack in a tile or grout line and risks causing structural damage that can’t be seen and, as it’s behind the tiles it can be very expensive to repair.
In almost all cases, The Shower Dr can save you money, inconvenience and costly shower rebuilds if the repair is tackled quickly and with our proven and guaranteed shower seal system.
