A flat and level foundation is necessary for safe and sturdy decking. However, there will be instances when the ground will not be as level as you hoped it would be. In which case, you will have to make some adjustments to make it a suitable foundation for Ultradecking composite decking boards. Because standard decking requires additional effort to install, especially on uneven ground, many homeowners and builders use decking tiles instead. They are easier to install, require less maintenance, and can be removed and reinstalled when necessary. The best part is it works on any surface. But do you lay decking tiles on uneven ground? And what should you do if the ground is uneven?

What to do if the Ground is Uneven

Decking tiles today have interlocking mechanisms. Because of this, they are the easiest and quickest decking material to install. Homeowners who have no experience in construction or first-time DIYers will want to try using them out.

The first thing you have to do is to find a level foundation to install the decking tiles. You can install it on most surfaces, from the ground, concrete, or existing decking. But what if the foundation is uneven? Can you lay decking tiles on uneven ground? Fortunately, there are a few ways around this.

Prepare the Ground

If you plan to install the tiles on bare ground as a floating decking, you can adjust the height by digging the foundation. To do this, you will want to dig a few inches into the ground and remove all the weeds and grass. Next, you will have to tamper with the foundation to make sure it’s even and flat. Then, cover the area with landscaping fabric and gravel. Doing this can help prevent moisture and insect damage to the tiles, especially if you’re using wooden ones. You can also add a traditional decking frame if you wish to elevate the decking to a few inches off the ground.

Check for Cracks on Uneven Concrete Slabs

What if it’s an uneven concrete slab? For concrete slabs, you will want to detect any problems first. Check for water pooling issues and larger cracks. If possible, fix them before installing the tiles. More so if you are using wood decking tiles. If the concrete slab is uneven, you can make use of adjustable decking pedestals. You’ll likely find them in the same place you bought the tiles from. Alternatively, you can construct a decking frame tailored to adjust the uneven ground problem.

As for existing floors and decking, you can set the decking tiles directly on top of them. You will have to check on the quality of the existing decking, especially if it’s wood decking. Depending on the situation, you can also use decking pedestals to make your new decking area level.

Installing Decking Tiles

Once you find a suitable foundation for your decking, installing the decking tiles takes no time. First, measure the total decking installation area where you will lay the tiles. You will want to do this before ordering the tiles. It’s best to get a few extra tiles in excess to account for future replacements and repairs. Some tiles may be out of stock when you need them, leaving you with an unrepaired or unfinished decking project.

Once you receive your tiles, lay some tiles across all corners of your planned installation area. Then, one by one, attach the tiles using the interlocking system. Different decking tiles will have slightly different clipping mechanisms. You’ll want to consult your manufacturer if you have questions on how to clip them together.

If your decking plan has some curves or the installation area has irregular or rough edges, you can see the decking tiles according to your preferred cuts. Before you see them, you can use a cardboard piece the same size as the decking tile as a template. Mark and cut the needed shape on the tiles and use them as a guide when sawing the boards.

Things to Remember When Using Decking Tiles

As previously mentioned, decking tiles are some of the easiest and quickest ways to transform concrete, existing decking, and floors into a beautiful decking area. However, there are more advantages to using them.

Since decking tiles can be easily removed and replaced, they are easier to maintain than traditional decking. If you use vinyl or composite decking tiles, you’ll require even less maintenance. But because they are removable, they are perfect for people who only rent houses.

Disadvantages of Decking Tiles

However, there are a few disadvantages of using them as well. First, they are only a temporary fix and can be a disadvantage for some homeowners. Some decking tiles also have visible seams and gaps between them, which may be unattractive to some. Lastly, if you want to add value to your home, don’t expect anything from a decking made out of tiles. Instead, a full-sized traditional decking is more appealing and can add value to your home.

Decking tiles are excellent options if you want fast and easy-to-install decking. Even if you don’t even have ground, there are plenty of ways around it. In a matter of a few hours, you can achieve the decking of your dreams by installing high-quality decking tiles.
