Can You Install Composite Decking Over Concrete?
The short answer: Yes! Composite decking can be installed over concrete, and in fact, concrete is often an ideal surface for this type of installation. Let’s explore why this works so well.
Why Composite Decking Over Concrete Is a Great Option
1. Faster Installation
Concrete provides a solid, stable foundation for composite decking, which makes the installation process quicker and easier. There’s no need to build a separate base or substructure, so you can get your deck ready in less time.
2. Perfect for Updating Old Concrete Surfaces
If you have an old, worn-out concrete patio or walkway, replacing it with composite decking is an excellent way to revitalize your outdoor area. This allows you to upgrade your space without having to tear out the old concrete, saving both time and effort.
3. Prevents Weed Growth
One of the perks of installing composite decking over concrete is that it blocks weeds from growing through. The concrete acts as a barrier, keeping unwanted vegetation from sprouting up between the decking boards.
4. Concrete Is a Solid Base
Concrete is an excellent base for composite decking. Unlike materials like gravel or dirt, concrete is sturdy, moisture-resistant, and durable, which helps ensure the longevity and stability of your deck.
Things to Consider When Installing Composite Decking Over Concrete
Ensure the Concrete Is Fully Settled
If the concrete is new, make sure it has had enough time to fully cure and settle before installing composite decking. Concrete can take time to fully harden, and installing decking too soon could cause uneven settling or sagging over time.
Check for Potential Door Interference
Keep in mind that installing decking over concrete will raise the surface by a few inches. This could potentially block doors or entryways, making them harder to open. Before you install, check to see if any doors or other obstacles may be affected by the raised deck height.
