One thing about decking is that you can lay it on any surface. You can build a composite decking or wood decking on grass as well as a concrete surface. Homeowners who have a concrete surface in their homes already have a sturdy foundation for laying deckings. If you have a concrete surface and want to lay decking on it, you have reached the right place. Building decking on concrete is very easy. Let’s see how you can lay decking on concrete surface?
Laying Decking on Concrete Surface
You can easily build a deck on a concrete surface. How to lay decking on concrete is the same as constructing conventional decking but with little difference.
Step One – Gather the Materials Needed
If you want to lay decking on concrete, you will need tools to work with, including your decking board. First, you will need to get your decking either composite or wood decking. Ensure you choose a kind of decking that will last for years. Composite decking is durable and will last for decades. You will also need a measuring tape to know the extent of your decking.
Apart from that, you will need a hammer, markers, fasteners, screws, and a drilling machine for making holes in the wood. In addition, you will also need to get pressure-treated wood to make your decking frame. Pressure-treated wood has a prolonged lifespan. It will not rot, and termites won’t be able to damage the wood.
Step Two – Level Out The Concrete
Before you start to lay the decking on concrete, evaluate the concrete. Check if there is any spot on the concrete that needs repairing. If you notice a spot where rainwater pools, fix the area with cement mix to create a leveled surface. Allow the concrete to dry before you proceed to install the sleepers.
Step Three – Install the Sleeper
You can now start planning the layout of your sleepers. Use the chemical-treated planks as the sleepers if you want to lay decking on concrete. And if you don’t want to use wood as your sleepers, you can use metal sleepers. Some homeowners prefer using aluminum sleepers instead of wood since it’s not easily prone to damages. Aluminum is resistant to rot, termites damage, unlike wood. Apart from that, aluminum is also resistant to corrosion.
When you are planning the layout of the sleepers, ensure it runs perpendicular to the wood or composite decking. Arrange the sleepers so that they will face the wall and not run parallel to it. A reason for this is so that it will not impede water drainage.
After you have finished installing the sleeper, you can now proceed to install the joists on it.
Step Four – Install the Joists
The joist will serve as support for your decking. You have to Install the joist on the sleepers. It will keep water from getting to the joist. Also, when installing the joist, ensure that all parts are uniform. If a part of the joist is higher than another part, use a saw to trim it. And if it’s shorter, add shims to it to create an equal height.
You can now install your decking joists using screws and clips to hold the joist down to the sleeper. Connect the planks till you have finished constructing the joist. You should also ensure to leave appropriate spacing when building the joist. The joist should not be too far apart, nor should it be too closed.
Step Five – Lay the Decking on Concrete
Now that you have finished making the decking frame start laying the decking boards. Note that the decking frame comprises both the sleepers and joists. The decking boards are easy to install. Start to lay the decking on concrete from the side of a wall or an edge. Use clips and screws to fasten the decking boards.
When you want lay the composite decking on concrete, do not forget to leave a gap of 15 mm between the walls and the decking. And also, leave space of 5 mm between the composite decking boards. It will make the composite decking expand freely without warping when there is a temperature change. After you have laid the decking on concrete, you can now finish the edges to make it more beautiful. You can paint the edges with a matching colour as your composite decking or use picture framing.
How to lay decking on concrete surface is easy. You have to get your materials ready, level out the concrete, and install the decking frame. After that, lay your decking board on concrete.
