Leaky toilets can be a homeowner’s nightmare, causing a cascade of problems from damp walls to compromised structural integrity. Water seeping under tiles is not just an aesthetic issue; it can lead to long-term damage such as mold growth, flaking paint, and even spalling on RCC slabs. In this article, we will explore a comprehensive three-tiered approach to waterproofing toilet floors without the need to break any tiles, offering a faster and more cost-effective solution to the persistent problem of water leakage. Feels like too good to be true? Not really, it is possible by all means. Read on to know how this can be done.

The Perils of Water Seepage: Understanding the Consequences

Before diving into the solution, let’s understand the perils of water seepage under tiles. The consequences go beyond just a wet floor; damp walls, rooms below getting damp, and the prolonged exposure resulting in mold and fungus growth, flaking paint, and spalling on RCC slabs are all common issues which can ultimately lead to structural issues.

  • Mold and fungus not only pose health risks but also lead to an unpleasant odour in the affected areas.
  • Flaking paint not only ruins the aesthetics of your home but can also be a sign of underlying dampness which can cause irreversible damage.
  • Spalling on RCC slabs weakens the structure, compromising its durability and safety.

Therefore, it is important to address water leakage promptly to prevent these issues from escalating.

Water seeping under tiles is not just an aesthetic issue; it can lead to long-term damage such as mold growth, flaking paint, and even spalling on RCC slabs.

Introducing the Three-Tiered Waterproofing Approach

Unlike conventional waterproofing methods, the three-tiered approach designed by UniPro®’s technical team is a revolutionary solution that tackles the problem at its core. Let’s break down each tier to understand the process:

Tier 1: Creating Grooves between Tile Joints

The first step involves creating grooves between the tile joints in the floor area. This is a meticulous process that requires precision to ensure that the grooves are adequately spaced and aligned. These grooves serve two purposes:

  1. It helps the waterproofing compound (which is done during tier 2 step) to percolate and saturate the under-tile cement structure so that it can reduce the water absorption, post treatment.
  2. It also helps achieve a watertight seal between already laid tiles and grooves help the epoxy stay there for many years to come.

While creating grooves/tile gaps, special equipment are used to create grooves at the right angles which ordinary rotary grinding blades cannot achieve. The vertical wall area of 4 inches from tile floor are also grooved to avoid water ingress in case of flooding. Other parts of the vertical walls aren’t touched as normally only floor leaks cause 99% of the leaks, other than issues such as plumbing leaks, gratings-trap joints etc.

Tier 2: Chemical Ponding for Waterproofing

After creating the grooves, the next step is to perform a waterproofing chemical ponding in the floor area. This process involves closing the drains and allowing a specially formulated waterproofing chemical to percolate through the grooves created into the under-tile cement area of the floor overnight. This once dried acts as a barrier, reducing the water absorption and further percolating it to the drier areas underneath causing dampness.

Tier 3: Sealing with High-Quality Epoxy Tile Grouts

On the second day, any residual chemicals are removed and allowed to dry. In many cases, the ponded chemicals disappear into the under-tile area in just 30 minutes time after ponding is done! Once the floor has dried, the final tier commences. High-quality epoxy tile grouts of client’s choice are used to seal the grooves created in Tier 1. Epoxy grouts are known for their durability and water-resistant, and abrasion resistant properties, ensuring a long-lasting solution to keep water at bay. This step not only enhances the aesthetic appeal of the tiled floor but also reinforces its resistance to water seepage.

We have noticed many times that homeowners want to repaint the flaks paints immediately after they have addressed the leaking toilet floor issue. What we have to under stand here is that, the further wetness is stopped. What about the dampness which is already there in floor and walls?

As you can understand, it will take months for the dampness to get dried up. Hence it is advised to hold on with the repainting for few months so that the moisture can escape and walls can dry up.

In case you don’t want to wait for that long, consider doing a Moisture Barrier Treatment (MBT) on the walls and then do the painting process. Moisture Barrier Treatment can be done on a damp wall and can handle immense negative water pressure.

Disclaimer: There are many reasons for a toilet to leak such as leaks through the tiles, plumbing leaks, pipe joint leaks, drain-trap leaks etc. The process above only addresses the issue of leaks through the tiles. Other issues if found, have to be addressed employing the services of a qualified plumber.
