Why is my grout cracked, loose or missing?

Cracked, Loose or Missing Grout

Cracked, loose or missing grout can detract from the looks of a finished tiled surface. Once you see this happening it could be the first signs of more than just poor grout finishing techniques. Often customers think they can just repair grout when they find it missing or dislodging. When grout becomes missing or dislodged there is usually an underlying issue.

Delaminated Tiles

When tiles have become delaminated, loose, hollow or drummy there tends to be some movement between the tiles and adhesive. With foot traffic, this can cause tiles to move slightly up and down loosening the grout joints. With every run of the vacuum, piece by piece the grout will slowly disappear. Once the grout has gone this leaves the tiles exposed to even more damage. With constant (even if slight) movement of the loosening tiles, there is the chance the grout pieces can work their way under the tiles. When chunks of grout get under the drummy tiles there is a high chance the tiles will break or crack.

Broken and Cracked Tiles

Broken and cracked tiles are dangerous tripping hazards and generally have sharp edges. Once you start having broken and cracked tiles the repair job becomes a little harder for the repairer. This is usually due to being left too long so there may not be any spares for replacement. If this is the case you may have to select a new tile that is a close match. In summary, the sooner you uncover the reasons why you have cracked, loose or missing grout the easier the repair. If the cause is loose tiles, the good news is – we can fix it! The even better news is that you won’t have to rip up your whole floor to do it. We can repair with the tile injection system firming up their foundation and giving new life to your tiles.

Does my furniture need to be moved out before treatment commences?

The advantage of the tile injection system is you do not need to move out of your home or business. As a result, tile injection is a clean and easier repair process in comparison to lifting and relaying tiles. You won’t even have to move your furniture out of the house (only away from the drummy tile treatment area). For instance, furniture can be moved to the other side of the room if needed. In some cases your furniture may not need to be moved at all. However, we will be sure to advise you on this during your assessment period.

Is it cheaper than having new tiles laid?

Yes it certainly is – much cheaper than the cost of re-tiling. This is because we do not need to pull everything out and start again. Below are some examples of what factors a tiler will have to do to repair your floors. As there is so much more labour intensive work involved in re-tiling, there is no doubt you will be charged accordingly.

There are various factors that could contribute to the cost of re-tiling your home or office space. These factors could include

  • Jackhammering to remove tiles
  • Grinding remaining adhesive on substrate
  • Dumping fees
  • Purchase costs of new tiles – Type of tile – e.g. porcelain, feature tiles are more expensive
  • Purchase of new grout, glue and materials
  • Labour costs of re-laying new tiles
  • You may need to pay for storage as you will have to remove all furniture from the newly tiled area
  • Accommodation – you may be required to find alternative accommodation during retiling (depending on the scope of works of course)
  • Cleaner – in some cases you may have to hire a cleaner due to excessive dust and mess
  • Time waiting to return home or back to normal routine

At Tile Injection Solutions Australia there is NO:

  • Jackhammering 
  • Grinding the substrate
  • Dumping fees
  • Purchase costs for new tiles
  • Storage costs
  • Moving furniture out
  • Accomodation costs
  • Moving yourself out
  • Dust or mess to clean
  • Waiting days to walk on your floor

All equals a huge saving on your part. It really does save time, stress and money $$. In most cases you can be walking back on your floor within hours of treatment. We will also leave your floors cleaned and polished.

We Care About The Environment

Does tile injection really work?

Does Tile Injection Really Work?

Yes, it certainly does. The injection process is carried out by drilling small holes in the grout lines. After that, we inject a specialised liquid glue through the grout joint and under the drummy / drummie, loose or delaminated tiles. Our glue / adhesive is both strong and flexible. This creates a new bond between the tile and substrate, which will hold for many, many more years. All without the hassle of jackhammering tiles up or grinding old adhesive off the substrate. Therefore, no dust throughout your home and no need to move out. Importantly our repair method is cost effective and enables our clients to have an alternative option other than tearing up their floors. Our tile injection service also comes with a 7 year guarantee.


Marc has been a tiler for over 25 years and a highly sought after tiler also. He too was sceptical about the process, until he realised what a huge problem drummy tiles were. Especially in the Northern NSW and South East Queensland region. Marc has a high knowledge of ceramic floor tiles and the issues they bring and the why. Above all, he will always give you honest answers to your inquiries and listen to your concerns.


We have many satisfied customers and this one below is one of our all time favourites – Thank you Brian!

I never would have believed it would work so well. Marc Huwart was my tradie who did the job. He was so professional and clean. Thank you Marc. Saved me thousands of dollars and all my drummie tiles are no more. A wonderful product with the perfect tradesman.

Why are my tiles drummy?

Drummy tiles occur for various reasons, such as the following

  • Inadequate adhesives on initial installation
  • Insufficient amount of adhesive / glue used on the initial installation. Floor tiles should have full coverage upon initial installation
  • Thermal conditions, such as the expansion and contraction of tiles and substrate due to weather conditions, heating or cooling
  • In some wet areas or where flooding has occurred. Water that sits under tiles could eventually cause the adhesive to break down
  • Tile adhesive or glue has debonded or separated from the substrate creating a void
  • The tile adhesive or glue has separated from the tile itself causing a void
  • The tile adhesive or glue had skinned over when initially laid. This can negatively affect the bonding of tile to glue
  • The incorrect type of adhesive or glue was used upon initial installation
  • Movement of the substrate
  • Dobbing of tile adhesive or glue used on initial installation causing voids
  • Incorrect floor preparation when initial installation occurred
  • Tile on Tile. When tiles are laid over old tiles it may be the older tiles beneath that are drummy

Please Note

If you have noticed a hollow or drummy sound in your floor tiles you should not delay in seeking repair advice from us. The longer you leave hollow or drummy flooring the higher the risk is of tiles cracking or lifting under foot.

What is tile tenting?

Tile tenting is when floor tiles have lifted, popped or buckled from their originally installed position. Tenting tiles occur when there have been changes in the environment or circumstantial to their initial installation. Movement in substrates e.g: concrete foundations, expand and contract with thermal conditions. A tiled floor system consists of layers of concrete, adhesive and then the tiled surface. Concrete moves differently to floor tiles. The substrate remains cooler than the tiles because it lays beneath the flooring.

Tile tenting can occur when the tiled surface is exposed to thermal conditions like sunlight, fireplaces or heaters. This can cause the tiles to be at different temperatures to that of the concrete foundations. The differences in temperatures may cause movement in opposite directions, causing stress on the tiles and grout joints. Inadequate room for movement, (no expansion lines placed throughout the tiled surface) may cause perimeter stresses and pressure build up. Pressure can cause tiles to tent, lift, pop, buckle and possibly let go altogether.

In a tenting failure, the tiles usually de-bond leaving the adhesive on the substrate. Sometimes this can be misinterpreted as a sign of a poor quality adhesive. Mostly, it is actually a sign of a good adhesive. Concrete and adhesive typically bond well together because they are made of similar cement based products. The bond between tile and adhesive is slightly weaker. The point of failure will occur at the weakest point. Another common failure is when the adhesive comes clean of the substrate and remains on the tile. This indicates poor surface preparation (i.e. tiling onto a dusty floor and inadequate priming of substrate).
