How to Stop a Leaking Shower Without Removing Tiles

Posted on 2018-11-30

Can you DIY?

For the budding property owner there is always the option of doing it yourself (DIY). Unfortunately, most products available in the general retail market, even if applied correctly, will often only provide a temporary solution.

You are also only likely to target the area in the bath or shower where you can visibly see a gap in the grout or between the floor and wall tiles when there may be other leaking areas you have not and are not able to identify.

What makes this option even less ideal is that after all the hard work of doing it yourself, silicone based retail products tend to go mouldy within a very short amount of time and in general most products may not withstand building movement.

The most expensive way to stop a leaking shower

When Megasealed first opened its doors over 24 years ago most Australians with a leaking shower were forced to use temporary stop-gap measures or expensive, time-consuming and destructive re-waterproofing measures.

Re-waterproofing is not an easy task and can take 4-5 days. It involves the removal of tiles within the shower to repair or replace the current waterproofing membrane and it can be extremely difficult to find matching replacement tiles – making it costly and time-consuming.

We usually recommend our Megasealed service which repairs shower leaks behind walls and floors. However, we can complete a full retiling and membrane service if necessary or preferred.

The most efficient and effective way to stop a shower leak

In many cases the Megasealed service which does not require removal of tiles is by far the most efficient and effective way to stop a leaking shower. Our leak detection service reduces the cost and uncertainty related to the repair of shower leaks behind wall and floor tiles.

Service product options

Megasealed is a unique product exclusive to Megasealed and designed to withstand normal building movement more so than standard grout. It is applied to wall and floor joints in replacement of standard grout to permanently stop your leaking shower.

Megagrout MG14 is a liquid additive mixed with grout prior to application to help with flexibility and porosity. As with the Megasealed product listed above, the product is also a 2 part epoxy product exclusive to Megasealed and is ideal for grout replacement. The decision to use Megagrout or Megasealed is up to the customer, and their preference towards the two textures.

Penetrative Sealer is applied to wall and floor grout and tiles in showers and balconies to prevent leaks. It also seals porous natural stone tiles such as marble, granite and slate.

Leak detection test – an electronic moisture meter may be used to determine the level of concealed water behind tiles. Thermal imaging cameras may also be used to aid in diagnosis of onsite issues.

Further testing- In certain cases your Megasealed Consultant may recommend further leak detection to be carried out by a plumber to investigate potential plumbing issues. In this case your consultant can usually organise a plumber on your behalf to attend and carry out pressure testing, spray testing and flood/dye testing where applicable.

The Processes

    3. Removal of existing grout from the walls and re-grout where necessary. (We do not remove cement based grout to minimise risk of damage to existing tiles).
    4. Remove and replace damaged floor grout where necessary (unless cement based).
    5. Remove and replace old grout from around the waste (drain) section as needed.
    6. Prepare the floor and wall junctions using Megasealed diamond tip technology.
    7. Remove waste material and vacuum excess dust.
    8. Remove and replace old silicone with mould resistant Megaflex or high grade silicone inside shower screens to ensure water can’t get under the screen.
    9. Apply appropriate Megasealed sealing product for your shower to joints and waste (drain) as needed. Megasealed is applied wall-to-wall, perimeter of floor, vertical joints to the first row, edges of floor waste and all floor joints if required.
    10. Inspect all work for quality on completion and ensure its left clean and tidy.

    Note: In some instances the steps above may be varied to suit the type of condition of the shower.

After service

Please leave the shower to dry for 24 hours before using. There may be a fine white powder left on your tiles. This is simply re-grouting residue that can be wiped off with a damp cloth.
