Waterproofing in Toilet: Why it is Essential for High-Rise Buildings

  • June 5, 2024

Ignoring waterproofing during construction may lead to the development of mould, breakdown of tiles, and even structural instability. A 2016 Australian study found that a massive 80% of a building’s defects are caused by water damage due to leaks, even though waterproofing makes up a mere 1% of building expenses. 

The bathroom waterproofing procedure is critical because it keeps water from leaking through walls, floors, and ceilings, which may result in expensive repairs and structural damage.

Why whaterproofing in bathrooms necessaryWaterproofing is a crucial feature of construction, especially in high-rise structures. The process of waterproofing involves applying a waterproofing paint coat or other waterproofing techniques to provide a barrier against water infiltration. Proper bathroom waterproofing and waterproofing in toilet areas are essential for maintaining the integrity and longevity of high-rise buildings.

What is Waterproofing?

Waterproofing is crucial in bathroom construction, especially in toilet areas. It involves applying a water-resistant barrier or other waterproofing methods to protect the surfaces from water damage. Preventing water seepage is the primary goal of bathroom waterproofing. Water seepage can cause moulds, structural issues, and other damages.

Bathroom waterproofing typically involves several steps, including preparing the surface, applying a waterproofing membrane or other waterproofing materials, and sealing the floor slab and walls with a bathroom waterproof chemical. This process creates a continuous layer of protection, preventing water from seeping through and causing damage.

Waterproofing in toiletsProper bathroom waterproofing is vital for both sanitary and structural reasons. It helps maintain a healthy living environment by preventing moisture buildup, which can lead to mould growth and other health hazards.

Waterproofing in toilet areas is particularly crucial due to the frequent exposure to water from plumbing fixtures and the potential for leakage. Inadequate waterproofing in these areas can result in costly repairs and potential health risks.

Why is Waterproofing Essential in Bathrooms and Toilets?

Here are a few reasons why waterproofing is vital in bathrooms and toilets:

  • Constant Water Exposure in Bathrooms and Toilets

It is important to do waterproofing in the toilet area and the bathrooms because they are usually exposed to water from plumbing fixtures like showers, bathtubs, basins, and toilets. Water can freely enter the floor slabs, walls and any other construction gaps that may be in place when these have not been sealed, leading to seepage and lots of structural damage to the building.

  • Protecting Building Elements from Water Penetration

This is done through the use of waterproofing methods like using a waterproofing membrane, sealant, or coat, to achieve the right degree of waterproofing in the bathroom. This barrier protects the structure of a bathroom and eliminates the need to spend a lot of money on future restoration works to repair the damages that water may have caused to building structures, including floor slabs, walls, and other working surfaces.

  • Preventing Mould and Fungus Growth

Since water is more likely to accumulate in the bathroom, moulds and fungi are more likely to develop here. This is why bathrooms need to be well protected with materials that do not allow water to seep in. This helps tackle the common causes of respiratory diseases, such as mould and fungus growth, as they are unable to thrive due to the waterproofing of bathrooms.

  • Deterring Pests like Carpenter Ants and Termites

The exclusion of carpenter ants and termites from further reproduction and the destruction of the building as a result of their activity are also due to the waterproofing of the bathroom. In this regard, waterproofing prevents the growth of these pests by removing the source of moisture from the bathroom and, subsequently, protects the integrity of the building.

  • Cost-Effective Long-Term Investment

In the long run, it is a better cost-saving strategy to ensure proper bathroom waterproofing when constructing or remodelling. It also significantly reduces calls for expensive repair and maintenance costs that are associated with structural defects, mould, and water damage. Waterproofing ensures a healthy and strong house construction, a good living standard, and financial stability of the occupants’ health is protected.

Methods of Waterproofing Coatings for Toilets

Here are a few techniques for good waterproofing of toilets:

  • Epoxy Resin Coating

A common method of waterproofing toilets is an epoxy resin coating. The surface is firmly coated by a seamless, resilient layer of epoxy material. This material is appropriate for high-moisture areas, such as toilets, due to its exceptional resistance to abrasion, chemicals, and water.

  • Cementitious Waterproofing Coatings

These cementitious coatings can waterproof both the positive and negative sides of a surface while being breathable. This material is optimal for waterproofing in bathroom and toilet areas, as it prevents moisture infiltration while allowing the surface to breathe.

  • Bituminous Sheet Membrane

Bituminous sheet membranes, including self-adhesive membranes (SAM), are a form of cold-applied waterproofing method that is appropriate for toilet waterproofing. The bitumen-based material is directly applied to the surface, resulting in the formation of a durable and malleable layer that obstructs water penetration.

  • Bathroom Floor Waterproofing

Several different waterproofing methods can be used for bathroom floor waterproofing. These include liquid-applied membranes, sheet membranes, and specialised coats for waterproofing bathroom floors. The decision depends on the budget, moisture exposure, and surface material.

  • Toilet Waterproofing

For making toilets waterproof, selecting a waterproofing method that can withstand frequent exposure to water and moisture is crucial. Because of their durability and capacity to establish a seamless barrier around plumbing fixtures and corners, epoxy coats, cementitious coats, and bituminous sheet membranes are widely used.

It is imperative to employ appropriate surface preparation, priming, and application techniques to guarantee the effectiveness of waterproofing bathroom and toilet areas. Regular inspections and maintenance can assist in identifying and resolving potential issues, thereby guaranteeing long-term protection against water damage.

Procedures for Waterproofing in Toilets & Bathrooms

Proper waterproofing in toilet areas is necessary to preserve a sanitary environment and prevent leakage. The following steps are the most frequently used waterproofing method for toilets:

  • Surface Preparation

Before applying any waterproofing material, the surface of the toilet area must be thoroughly prepared. This entails the elimination of contaminants, loose particles, and grime. To prevent any defects that could impact the adhesion of the waterproofing membrane or sealant, the walls should be brushed and polished.

  • Priming of Toilet Surfaces

Priming is an important stage in the waterproofing method. A bathroom waterproofing chemical primer is applied on the walls and floor surfaces of the restroom area. This material guarantees enduring protection and improves the adhesion of the succeeding waterproofing layers.

  • Bond Breakers

Bond breakers, including silicone and tape, are deployed around plumbing fixtures to guarantee that the waterproofing is applied up to the necessary height. Corners and junctions are considered due to their susceptibility to water penetration.

  • Application of Waterproofing Membrane

The lavatory area is meticulously coated with the waterproofing membrane, which is frequently a liquid or sheet material. A liquid membrane is typically applied with a paintbrush to guarantee complete coverage, particularly in critical areas such as corners, connections, and around plumbing fixtures.

  • Coating Application

A second coat of the waterproofing membrane is applied after the first coat has dried, emphasising the corners and junctions. Each coat may use different colours to guarantee full coverage and designate any overlooked areas.

  • Waterproofing Testing

After the waterproofing treatment is completed and the coating materials have been set, it is necessary to test the coat for any misapplications or leaks. To do this, water needs to be poured on the treated areas and made to stagnate there for a minimum 24 hours. The areas are then examined for leaks. If there are any, the waterproofing procedure needs to be performed again. 

Additional Measures

Additional waterproofing methods may be used occasionally. For instance, in addition to the liquid membrane, membrane sheeting may be affixed to walls, floors, and joints to provide extra safety. This is particularly important in regions that are susceptible to elevated water exposure or movement.

Bathroom waterproofingTo prevent water damage, mould growth, and other issues that could compromise the structural integrity and sanitation of the building, proper bathroom waterproofing, particularly in toilet areas, is crucial. Adhering to these waterproofing methods can ensure a sanitary, safe, and long-lasting toilet environment.

Bottom Line

Maintaining a safe, healthy, and structurally sound living environment necessitates the implementation of appropriate waterproofing in toilet and bathroom areas.
