Is Cracked Shower Tile a Major Problem?

Share this:

A cracked tile in your shower might not look pretty, but it’s not just a matter of aesthetics. At the heart of it, tiles act as a protective layer for your waterproofing system. When a tile cracks, it compromises the waterproof barrier. This can allow water to seep into the walls and subfloor, which is not only a potential headache but can lead to extensive water damage, mould growth, and structural issues. If water gets behind the tiles and isn’t noticed, it could lead to bigger, more expensive repairs down the track.

What Causes Cracked Shower Tiles?

A study of QBE Insurance Australia reveals that water damage accounts for almost a quarter (24%) of all home insurance claims in Australia, making it one of the most common types of home repairs required. The average claim plays at around $5,000, while more severe claims reach over half a million dollars. A small crack today could turn into thousands of dollars in repairs tomorrow if left untreated.

Here’s why your tiles crack in the first place:

  • Impact from dropped objects, building movement or foundation shift, poor installation, or inferior materials can all lead to cracks in shower tiles.​
  • Installation mistakes like improper adhesive or a poorly prepared substrate are frequent culprits.
  • If water manages to seep behind the tiles due to poor waterproofing or damaged grout, the tiles can loosen or crack. Constant moisture weakens the adhesive and grout, leading to tile damage and, in some cases, a complete detachment.

Here are some of the reasons why cracked tiles should not be considered lightly:

1. Water Leakage and Damage

Cracks in shower tiles compromise the waterproof barrier, letting water penetrate below the surface and into the substrate or floor. In addition, persistent moisture underneath tiles can rot framing timbers, degrade waterproofing membranes, and encourage the growth of mould or bacteria, which may threaten indoor air quality.

2. Structural Risks

Unrepaired cracks have the potential to worsen over time, allowing further damage to supporting structures, which could undermine the shower base or even the overall stability of the bathroom.

3. Hygiene Issues

Moist environments resulting from cracked tiles serve as breeding grounds for mould and harmful bacteria, risking occupants’ health and increasing cleaning or remediation costs.

Can You Fix Cracked Tiles Yourself?

While some minor tile repairs can be DIY projects, fixing a cracked shower tile is often best left to the professionals. If you’re dealing with a single cracked tile and there are no signs of water damage, you might be able to replace the tile on your own. However, if the crack is part of a larger issue such as an unstable foundation, water damage, or faulty waterproofing, you’ll need to bring in a shower repair technician.

Superficial repair attempts (like covering cracks with silicone) are usually temporary. Long-term moisture below the surface prevents proper sealing and may cause repairs to fail quickly.​ So often this requires removing damaged tiles and checking waterproofing, sometimes needing a full section replacement

Professional technicians have the tools and expertise to assess the cause of the crack, repair it properly, and ensure the waterproofing system remains intact. In many cases, a quick fix today can save you from needing a major renovation tomorrow.

SETTING NEW BENCHMARKS WITH OUR HIGH QUALITY REGROUTING SHOWER SERVICE

There are many ways you can renovate your bathroom but if you’re looking for a quick and budget-friendly fix, regrouting tiles is the key.

The DiamoSmart® System, copies of which are now used throughout the industry, was pioneered by our founder, Mark Studdert. Before its invention, Mark noticed that the old method of regrouting showers caused small but visible chips to the edges of tiles and diminished the lustre of the tiles’ edge. He designed a small diamond-tipped grouter that would eliminate these issues when regrouting bathroom tiles. Our team offers a Diamond Re-Grout Service where we strip off existing grout and replace it with a premium Epoxy grout, which is more resistant to stains, cracks, harsh weather conditions, chemicals, and climate changes than traditional grout. This makes it suitable for areas with high traffic and since it’s a waterproofing grout, it improves not only the bathroom’s aesthetics but also its functionality.

FAQ’s

The purpose of the grout is to emanate an unblemished tile appearance, while bonding the wall junctions and the floor and wall junctions – preventing wall and floor separation.

Grout mixtures must be selected carefully to make sure that dirt and other outside elements like mould and mildew will not seep into the tiles to avoid discoloration and possible leaks.

There are various ways in which installation can cause cracked grout in shower:

* If mixed with too much water concentration or additives

* If too little adhesive is used in tiles installation

* Cement-based grout can only handle the pressure for so long if a tile pulls away from the wall after the adhesive dries

Fact: Grouting is the weakest link in a tile installation.

Cracked grout in shower mainly happens due to movement between two surfaces with homes inevitably moving in tiny increments because of humidity, foundation settling, and temperature.

Even old or damaged grout can make the most beautiful looking tiles ugly and not to mention, it can cause structural damage to your home. Thus, immediate regrouting shower service is needed.

Regrouting showers and tiles is a quick and budget-friendly fix if mould has already grown into some parts of your bathroom. We highly recommend using epoxy over cement-based when regrouting tiles because it’s stronger, more durable, and only requires light maintenance.

At the first sign of grout damage, you must regrout shower tiles immediately. The longer showers are left with failing grout, the higher the chance that water damage is occurring to the wall behind your tile. The area of damage does not have to incur direct water spray during baths or showers to allow water seepage. Water that sits on the surface of tiles from shower spray or heavy steam will inevitably run behind the broken areas of your grout

Before the invention of the DiamoSmart® System, the old methods of tile regrouting caused small but visible chips to the edges of tiles and diminished the lustre of the edge of the tiles. The DiamoSmart® System eliminated this issue. Our exclusive procedure for regrouting showers is listed below:

* Remove any mouldy or deteriorated sealants such as silicon

* Strip the existing grout out of the walls * Strip out any damaged grout from the floor area

* Strip out grout from around the drain

* Prepare floor and wall junctions using our DiamoSmart® system. This system uses a diamond-tipped blade for regrouting bathroom tiles, removing the sheen from the tile edge creating a small gully in wall and floor junctions.

* Inject our SealRight sealant into the gully so it bonds the wall junctions and the floor and wall junctions – preventing wall and floor separation.

* Regrout bathroom walls and floor using commercial grade mould retardant grout

* Apply silicon to the internal areas of the shower screen

* Coat the internal shower area with our hydro barrier sealant creating an invisible glove to prevent water penetration. This sealant is painted or sprayed on the wall and floor tiles, waterproofing grout surface and beneath it. This soaks in and seals anything that is porous, such as grout lines and hairline cracks.

 

When regrouting showers and tiles, the type of grout matters and you should know that Epoxy grout is the most superior of all. Here’s why.

Unlike traditional grouts, Epoxy grout is made of two-part epoxy resins which are mixed with filler powder.

What does that mean?

Its composition makes it:

* Waterproof
* Nearly 100% resistant to stains
* Highly resistant to chemicals and physical pressure
* Doesn’t need sealing
* Low maintenance

These characteristics make Epoxy grout the best for regrouting shower and bathroom tiles. Its stain, crack and chemical-resistant properties make it suitable for areas with high traffic whilst its resistance to climate changes make it ideal for locations with harsh weather conditions, excessive amounts of humidity or severe cold. What’s even more interesting is that Epoxy grout’s colour remains constant throughout. The pigment of traditional grout can diminish easily during cleaning.

Moisture and direct water contact contribute to grout deterioration over time, and eventually, the tiles will crack. This is why you should consider regrouting shower tiles every six months. This is a quick and budget-friendly fix that can restore your bathroom’s previous glow immediately.

You should know that you need to call in a professional to do the tile regrouting for you. Even if you possess excellent handyman skills, small mistakes can lead to extensive damage to your grout and tiles. The cost to regrout shower is expensive and if the grout is not installed correctly, moisture can seep into small holes, causing mould and mildew growth, and may cause you to call for a regrout service earlier than expected.

Cement-based grout is actually the weakest link in tile installation because of its many drawbacks with the major being its porous nature. Its pores allow dirt and other outside elements to find their way into the grout, causing staining and allowing mould and grime to embed themselves into the grout, which requires an urgent regrouting shower service.

The best way to prevent grout from cracking is by using Epoxy grout which is strong, durable and requires light maintenance. Whilst it costs higher than cement-based grout, it lasts much longer, negating the cost to regrout shower.
