Deck tiles are an easy way to upgrade the appearance of a concrete patio or wood deck or install a new walkway or patio. Interlocking tiles made from wood or stone can add texture, color, and pattern to outdoor spaces with significantly less work than cutting and fitting individual decking boards or pouring concrete. But what happens when you have an uneven surface?

In this post, we offer some tips on how to install deck tiles on uneven surfaces to achieve beautiful, long-lasting, and safe stone porches, decks, patios, or walkways.

Is Uneven Ground a Problem for Deck Tile Installation?

Deck Tiles on Uneven Surface

Any time you perform tile installation inside your home, it’s critical to have a perfectly level surface. Installing tile over a floor that isn’t completely even can cause tiles to shift, cracking the grout and, in some cases, the tiles themselves. 

When working with deck tiles outdoors, it is possible to install them over uneven ground or an uneven concrete surface. You can even cut tiles to fit oddly shaped areas for a custom, finished look.

Some homeowners use a flexible mat underneath the tiles to create a stable surface, but because the mats will bend and flex to fit the contours of the surface underneath, the tiles still won’t be perfectly level. 

Installing Deck Tiles on Uneven Surfaces

If you would rather have a level, flat surface for your deck, patio, or walkway, one option is to invest in landscaping and earthwork to prepare the area for tile installation. Installing the tiles over a newly built deck using the frame as a guide is also ideal.

However, when you’re remodeling or updating, and have to work with what’s already in place, knowing how to install deck tiles on uneven surfaces is important. You have several options:

  • Use a sturdy base that doesn’t conform to uneven ground and supports the tile weight.
  • Use structural deck supports to float the deck tiles above the concrete pad.
  • Use a concrete leveling kit to raise sagging or uneven sections of concrete on the pad. 
  • Use gravel to level the soil under the deck tiles.
  • Install a new frame on top of the existing pad.

Any of these options will provide a level surface for installing deck tiles to give your outdoor living area a fresh, high-end appearance.
