THE GROUT GUY How to Spot Water Damage Underneath Your Shower Tiles

Water damage under shower tiles can occur gradually over time or it can happen suddenly if there is a major shower leak. If the leak is small and goes unnoticed, it can take weeks or even months for water damage to become apparent, so it’s important to be vigilant and know how to identify the signs.

Common Causes of Water Damage Under Shower Tiles

It’s important to address these common causes promptly to prevent further water damage and ensure the longevity of your shower tiles.

  1. One of the most common causes is a faulty waterproofing system. If the waterproofing membrane isn’t properly installed or has deteriorated over time, water can seep through and damage the underlying structure.
  2. Another common cause is cracked or damaged grout. When the grout is compromised, water can penetrate through the cracks and accumulate beneath the tiles, leading to water damage.
  3. Additionally, a damaged or improperly installed shower pan can also cause water damage. If the shower pan is cracked or not sloped correctly, water can pool underneath the tiles and cause structural damage.

Visual Signs of Water Damage Under Shower Tiles

  • Discolouration or mould growth on shower tiles. 
  • Check where the grout is cracked or missing, as this could be a sign that water is seeping through and causing damage. 
  • Bulging or warping of the tiles can be an indication that water has penetrated the surface and is causing the tiles to shift.
  • Soft or spongy areas on the floor near the shower.

How to Test for Water Damage Under Shower Tiles

If you suspect water damage under your shower tiles, one way to test for it is by using a moisture metre or a thermal imaging camera.

A moisture metre is a handy tool that can detect the presence of moisture in various materials, including tiles and grout. Simply place the moisture meter against the tiles and check the readings. If the moisture levels are higher than normal, it could indicate water damage.

On the other hand, a thermal imaging camera uses infrared technology to identify temperature variations. By scanning the tiles and surrounding areas, you can spot any potential water leaks or moisture issues.

Both of these methods can help you identify and address water damage before it becomes a bigger problem, saving you time and money in the long run.
