What Is Waterproofing Grout? And Why You Should Be Using It

When it comes to tiled areas like bathrooms, balconies, and wet rooms, water damage is one of the most common (and costly) issues homeowners face. While many people focus on tiles or membranes for protection, the real weak point is often what lies between the tiles: the grout.

That’s where waterproofing grout—specifically epoxy grout—comes in.


What Is Waterproofing Grout?

Unlike traditional cement-based grout, waterproofing grout is a non-porous, resin-based solution (like epoxy) designed to seal the joints between tiles completely. It doesn’t absorb water, doesn’t crack under pressure, and forms a durable barrier that protects the surface beneath the tiles.

At Supersealed, we use premium epoxy grout that is:

  • 100% waterproof
  • Stain-proof and easy to clean
  • Resistant to mould, bacteria, and discolouration
  • Long-lasting and low maintenance

Why You Should Be Using It

 Stops Leaks at the Source

Many leaking showers and balconies are caused not by the waterproof membrane, but by cracked or degraded grout. Waterproof grout seals the joints so moisture never gets through—protecting your substrate and structure.

 Ideal for Wet Areas

From showers and bathrooms to balconies and pool surrounds, waterproof grout is perfect for any area exposed to water. Unlike regular grout, it won’t absorb moisture or break down over time.

 Hygienic and Mould-Resistant

Because it’s non-absorbent, waterproof grout doesn’t allow mould, mildew, or bacteria to grow—making your spaces cleaner, safer, and easier to maintain.

 Looks Better for Longer

Waterproof grout doesn’t stain, crack, or fade like standard grout. Your tiled surfaces stay cleaner and more visually appealing for years to come.


Where Should You Use Waterproof Grout?

  • Leaking showers
  • Leaking balconies
  • Bathrooms & laundries
  • Outdoor tiled areas
  • Kitchens & splashbacks
