Why It’s Important To Waterproof Under The Tile

Let’s face it: tiling is a hell of a job. You have to measure, cut, and nail every single piece. If you’re not careful, you can mess up your tiles—which means more time for you to spend on the project. But another thing can make or break your tile installation: waterproofing under the tile.

Waterproofing The Floor Under The Tile Is Very Important In Preventing Possible Water Damage To The Subfloor

Water can cause mold, mildew, and other problems to occur. Also, if you have ceramic or porcelain tiles, they will peel, crack and bubble when they are exposed to moisture.

Waterproofing the floor under your tile is important to prevent any possible water damage to the subfloor. Improper waterproofing could cause peeling, cracking, or bubbling of the tile. Installing a waterproof barrier can protect against mold and mildew as well.

Waterproofing should be done on all surfaces that come into contact with moisture from below or above, such as walls, ceilings, and even concrete slabs in basements or crawl spaces. The membrane must be installed correctly, so it needs to be combined with proper ventilation (it’s best if you can leave an opening at least 10 inches high).

Installing A Waterproof Barrier Can Protect Against Mold Or Mildew

If you’re worried about mold and mildew, installing a waterproof barrier can help protect against it. Mold and mildew are common in areas where moisture is present for an extended period of time. They can cause health problems like allergies, respiratory infections, and asthma attacks, and even people with weakened immune systems may experience more severe symptoms. Furthermore, mold can stain tiles or destroy the grout between them—and once there’s a stain on your tile floors, it’ll be complicated to get rid of without professional help.

Mold also thrives on cellulose (paper products like drywall) which is usually used as subflooring underneath the tile in showers or bathrooms; if left untreated, this material provides an excellent breeding ground for mold spores since they’ll have access to plenty of food (cellulose). This causes damage not only to your floor but also to any walls being covered by tiles above it; not only does this make for an unsightly mess, but it also makes cleanup difficult because you won’t be able to remove just one layer at a time without damaging either layer below or above!

It Saves Money In The Long-Run By Preventing Costly Repairs And Replacements

Waterproofing is an important part of any home remodel. While the waterproof membrane under your tile will help protect against water damage to the subfloor and prevent mold or mildew growth, it also has many other benefits that are less obvious.

When you waterproof your space, you’ll save money in the long run because you won’t have to worry about expensive repairs caused by a small leak or broken pipe. Additionally, this small step can help maintain the value of your home by protecting it from major structural damage like flooding.

And both of those things can cause serious health issues for you and your family members if left untreated for too long. It might seem like an inconvenience now, but if you ignore that little leak for too long, it may cost thousands of dollars in repairs or replacements down the road.


You can see that waterproofing under the tile is an important step in protecting your investment. It will help prevent damage to your subfloor and protect against mold or mildew growth. If you are concerned about the cost, keep in mind that it’s less expensive than replacing old tiles or other flooring materials. Just remember to hire a professional who knows what they are doing so they don’t leave any holes behind after installing their membrane!
