When attempting to create a deck, a concrete stoop with stairs might be a significant hurdle. It will be tough to remove a large concrete stoop. Most of the time, you’ll need to use a sledgehammer or a jackhammer to break up the concrete and haul the debris away.
Installation of Composite Decking Over Concrete
Many individuals like to construct their homes over the stoop. Stop reading now if your project contains stairs leading up into a home or to a platform or landing that will not be covered with composite decking. The completed step will be about 3 inches taller than it was when you began. This will be a serious breach of the construction code as well as a life-safety threat. The risers above and below a step shall not differ by more than a fraction of an inch, according to the building code.
Furthermore, read the composite decking product’s installation instructions before embarking on this project. Pay particular attention to the needed minimum air space beneath the decking. You may find that one or more feet of free-flowing airspace is required beneath the decking.
Can you deck over concrete with composite decking?
Is it possible to build kompositterrasse (such as Trex) over concrete? Yes. In most circumstances, composite decking may be laid over concrete (but you’ll need to design a foundation that allows for ventilation and drainage). Concrete surfaces, in fact, may provide a dry, resilient, and sturdy surface that is suitable for composite decking. Covering a concrete area with composite, which comes in a variety of colors and designs, may be a quick and easy method to revive an area – especially when using Trex decking over a concrete patio.
However, evaluating whether or not you may build Smart komposit terrassebrædder over a concrete patio necessitates a thorough examination of other factors. Some materials that go over concrete may be better solutions in some cases, and some installations may need more labor than others.
Over a concrete patio: how to build a composite deck
Layout & Leveling
Before laying your sleepers, you’ll need to restore a worn patio surface (or one that isn’t completely even). To fix this problem, apply a thin concrete overlay to any low regions or uneven sections. You may even give the overlay a tiny incline to help water move away from your home.
After the room has been prepped, you may begin planning the layout. The position of sleepers and how each surface piece will exist in relation to each other should be included in your plan. You can construct a visual plan of your sleepers using 1-inch wide painters’ tape as an option to help guide your installation.
Installing & Placing Sleepers
Slender 1.5-inch broad pieces of ground-contact-rated treated timber are used as sleepers. You might be able to utilize 2x2s, but you might have to tear 2x4s if the 2x2s aren’t up to par.
Sleepers can either be laid directly on the concrete or separated with 12″ PVC spacers. The surface of the sleeper might be level or inclined as long as it forms a single flat plane. Place your first sleeper in place from the highest point on your patio, using plastic shims to lift low places if required.
Pre-drill the spacers, sleepers, and concrete with a hammer drill. Install concrete screws that penetrate at least 1″ into the concrete. Place more sleepers in the same way, using a straight-edge to make sure they’re all the same size. Finally, wrap the topside of each sleeper with joist deck tape. This tape prevents water from getting into cracks that form around screw penetration holes in the sleepers.
Putting composite decking on a concrete foundation
Decking planks are installed on sleepers in a similar manner to how they are installed on a standard deck. When installing decking, it’s critical to follow the manufacturer’s directions. In general, begin by screwing accent boards into place on the outside of the deck and work your way inward. Accent boards can be used to direct the placement of field boards.
Covering concrete steps with composite decking
It’s vital to remember that you can’t install composite decking over concrete stairs if the top riser height differs by more than a fraction of an inch from the rest of the stair set. Installing a ledger board on both sides of a concrete stoop is the first stage towards constructing it. Install double joists on either side of the stoop and a double header beam in front of the stoop in between the double joists to create a box frame around the stoop.
Install a 2×6 ledger board with 2×6 joists going out to the header to fill in the space above the stoop. The concrete stoop should not come into touch with the 2×6 joists. To allow for frost heaving, you may need to tear down the joists.
Installing composite decking over concrete may be a rather easy operation. However, there are a few things to keep in mind to ensure that your installation goes easily, produces a safe structure, and lasts the test of time.
