How do I install composite decking on top of concrete?

Family decks are becoming more and more popular. But every family is put together in a unique way. Today we’re going to learn how to put composite decking on concrete.

May I put the composite decking on top of the patio made of concrete?

Yes. Mix decks can be put down on concrete most of the time. Remember that you need to make a base that lets water and air pass through it.

One place where composite decks can stay dry, stable, and last a long time is on top of a concrete patio. It comes in a lot of different colors and shapes. It’s also quick and easy to cover the concrete area with plastic materials.

But you should also think about other things before you decide if composite decks can go on concrete.

Can you do your own DIY install?

Putting composite decking boards on concrete steps is usually a simple process. The concrete may settle over time, but sometimes it can take a few years.

Be careful of the sunk slope

You might not want to put a composite deck on top of concrete that is still sinking. The base may sink for more than 5 years after it starts to sink.

If you decide to build a new platform on the patio during that time. The new platform will continue to sink, just like the concrete floor.

Time and money

Putting a composite wood deck on a concrete slab is simple. However how long it takes to put the composite decking on the concrete front porch will depend on how big the area is.

It might take more than five days to finish a big job, but you can finish a small one over the weekend. The main thing that determines how long it takes is how many shims are needed to level the bed.

Most of the time, putting a composite deck board on concrete costs $30 to $50 per square foot. And it depends on the design, the site, and the type of composite that is picked.

These amounts will be cut in half if you do it yourself. Most of the time, labor and non-decorative materials make up two-thirds of the cost of a job.

Things that will be needed list

A circular saw, hammer drill, portable electric drill, chalk line reel, new floor, self-leveling composite, plastic gasket, flash tape, and concrete screws are some of the things you will need.

Layout and lengthwise

You need to fix the flat surface that isn’t quite right before you can lay the frame bottom. To fix this, put a thin layer of self-leveling powder on the spot that isn’t level.

You can start planning how the place will be set up once it is ready. The bottom frame should be clear on your plan, and each part of the surface should fit with the others. You can also make a picture of your plan with the chalk line draw to help you set it up.

Set up the bottom frame

You can put the frame of the keel right on the ground. The Joist can be straight up or down, at an angle, or at an angle to the floor. starting from the top of the deck. Place the first keel frame and use a hammer drill to make holes in the concrete, the gasket, and the keel frame.

Use concrete screws that go at least an inch into the ground to hold it in place. The next keel frames should be put in the same way as the first ones. Make sure that every keel frame is the same by using straight lines.

Screws can’t be used on concrete that has a waterproof layer on top of it. The glue should be used to keep the keel in place on the ground. Which can keep the waterproof layer from getting broken and make sure the whole thing is firm. Don’t forget that the screws you use now shouldn’t be too long. So that going through the bottom doesn’t damage the waterproof layer.

Putting down the composite decking on a concrete slab

It’s pretty much the same thing as building on regular decks or keel frames with artistic panels. It is important to do what the maker tells you to do.
