Why is bathroom waterproofing so important when renovating a bathroom?


Compared to any other area of the house, its the bathroom that is exposed more to moisture and water. Thus, a bathroom must be adequately waterproofed in order to prevent any permanent damage caused by water. Some areas receive more water than others on a regular basis in a typical bathroom. For example, the shower walls and the floors of a bathroom are exposed more to water than any other parts. So, waterproofing is really essential for these areas and there is a set of standard regulations that are followed for waterproofing services.

You must always get a sizable portion of your bathroom waterproofed in order to be on the safe side. This involves particularly the bathroom floor and the shower area. Get in touch with us today to discuss your requirements.

Procedure of waterproofing


Multiple coats of a waterproof membrane needs to be applied to the floors and walls of a bathroom under the process of bathroom waterproofing. There are certain things that needs to be taken care of before the coat is applied. Firstly, the joints between the walls and the floors and between the walls needs to be smooth. If any loose particles or rough edges are present then it can impact the functioning of the waterproofing membrane. A polyester reinforcement mat must be fitted in between the walls and in between the floor and wall. Once all this is done, the first membrane coat needs to be applied to the required surfaces. Usually, before the application of the next layer, there should be a gap of few hours. In this way, the first layer will be dry and it can be cemented properly on the walls. The two coats are to be applied in different directions like one coat along the wall’s length and the another across the breadth of the wall.

The membranes need some days to set in to the wall post its application. So, after the application of the waterproofing membrane you can’t use the bathroom for three to five days. The exact duration depends on the climate of the area you are staying and the construction material. Get in touch with our bathroom waterproofing experts for any queries.

Before laying tiles in the shower, the constructors put bathroom waterproofing into account. According to some of the councils in Australia, the bathrooms needs to be waterproofed to a height of 1800 mm. The waterproofing sealant can be placed at a height of 150 mm in case a wall does not get direct exposure to water. The waterproofing process is long and needs a shower repair expert with trade license. The house owners need to keep an eye on the waterproofing contractors and make sure the contractors carry out the right waterproofing. Thereafter, they also need to monitor the state of the bathrooms and carry out any form of leaking repairs, if required.

Bathroom waterproofing has various advantages:

  • Firstly, because of waterproofing,the bathroom remains dry a few minutes after usage. This makes the house neat and comforts the user.
  • A waterproofed bathroom prevents the formation of molds in the bathroom area and thus protects the users from serious health risks.
  • A waterproofed bathroom prevents the survival of carpenter ants and termites that may destroy other areas of the home.
  • It can also cause health risks and some other major damages such as shower leaking through wall.

There are various risks involved if one does not waterproof the bathroom. The various risks that are involved includes:

  • Leaking shower: If waterproofing is not done,the situation may result in a leaking shower.
  • Concrete cancer: If waterproofing is not done,the water might rust the steel that reinforces the slab. It can also make the timber boards rot. Any house will not last for long and will start cracking if proper waterproofing is not done.

Before waterproofing the bathroom, it should be cleaned and it needs to be free from dirt and dust. Secondly, primer should be applied on the bathroom walls and floor. Thirdly, any existing gap should be filled using silicone. Fourthly, the waterproofing membrane should be placed on the wall and floor areas that need bathroom waterproofing. Finally, the tiles should be applied.

The leakage in a bathroom always comes from the grout around the tiles. The problem can be solved by removing the grout and using a waterproofing product such as epoxy grout. In case of too much damage to the tiles, the re-tile service needs to be carried out in order to prevent the water from seeping to the walls or other areas of the floor.
