Composite Decking

Despite being a newcomer to the market, komposittrall outperforms wood decking in every way. It is made by combining polymer or resin with wood flour or sawdust. It is one of the best options for balcony trall since it looks wood but is non-combustible. As a result, you shouldn’t have any issues with planning or insurance.

Composite decking can be built on balconies in a manner similar to installing wood decking. It is most likely inappropriate for balcony railings in apartments since it requires a robust structure to which the boards can be fastened. Thinner boards, however, could be able to solve this problem. The main drawback of composite decking, one of the more expensive options, is its price.

Time and Price

Depending on the size of the space, lägga komposittrall over a concrete front porch may take some time. Depending on your skill level and the amount of support you can get, a larger project may take many weeks or weekends to complete while a smaller one can be finished in a single weekend. Aside from the size of the space, the quantity of shimming required for sleepers to make a level surface, the labor-intensive procedure of placing the sleepers, and the lay composite trolley, which requires time to perform right, will all affect how much time is needed.

Depending on the composite material selected, particular site variables, and design, the cost to lay composite trolley over concrete typically ranges from $30 to $50 per square foot. You can cut these numbers in half if you perform the job yourself (or perhaps even more). 2/3 of the overall project cost is generally made up of labor and non-decking materials.

Necessary tools


  • Level
  • Circular/Miter Saw
  • Banjo Drill
  • Portable Drill
  • Square Edge
  • Drawing Line Reel (Optional)
  • Deck replacement
  • Concealing Compound
  • A plastic shim
  • Banner Tape
  • drywall screws

Leveling and layout

Before lay composite trolley, the patio surface must be repaired if it is worn down or uneven. To fix this issue, apply a thin concrete overlay to any low regions or uneven surfaces. The overlay can also have a tiny slope added to it, allowing you to direct water to flow away from your home.

After the area has been set up, you can begin to arrange the layout. Your plan should, above all, show where the sleepers will be placed and how each surface component will interact with the others. You can, at your discretion, make a visual plan of your sleepers using 1-inch-wide painter’s tape to assist direct your installation.

Setting and attaching sleepers

Sleepers are thin, treated lumber pieces that are 1.5 inches wide and rated for ground contact. If the 2x2s are of poor quality, you might be able to use them, but you might have to rip 2x4s instead.

Sleepers can either be put up directly on the concrete or spaced apart by 12″ PVC spacers. As long as the surface of the sleeper is one flat plane, it might be level or sloping. Place your first sleeper in place beginning at the highest point of your patio, raising any low places as required with plastic shims.

Pre-drill the concrete, sleepers, and spacers with a hammer drill. Fix with concrete screws that extend at least one inch into the concrete. Using a straightedge to make sure each sleeper is identical to the previous one, place more sleepers in the same position. Finally, tape the top of each sleeper with joist deck tape. Water cannot penetrate fractures that often develop as a result of screw penetration holes in the sleepers thanks to this tape.

Installing composite decking

Decking board installation on sleepers is quite similar to deck board construction on a conventional deck. When lay composite trolley, it’s crucial to follow the manufacturer’s directions. In general, attach accent boards first by screwing them in place from the outside of the deck inside. The addition of field boards can be guided by starting with the accent boards.

It’s crucial to remember that if the top riser height differs from the other risers in the finished stair set by more than a tiny fraction of an inch, you cannot lay composite trolley over concrete steps.

Installing ledger boards on both sides of a concrete stoop is the first stage towards constructing it. By adding double joists on either side of the stoop and a double header beam in front of the stoop in between the double joists, you will basically create a box frame around the stoop.

Installing a 2×6 ledger board with 2×6 joists extending out to the header will fill in the space above the stoop. The concrete stoop shouldn’t come into touch with the 2×6 joists. To allow for frost heaving, you might need to tear down the joists. 

The procedure of lay composite trolley over concrete may be pretty straightforward. To ensure that your installation goes easily, produces a secure structure, and endures the test of time, it’s also crucial to keep a few things in mind.

How to install composite decking over concrete: installation advice

It may be completed in as little as four working days and isn’t as difficult as you would assume. Before you begin, consider these suggestions on how to lay composite trolley over a concrete patio:

attach the posts correctly

Attach posts correctly.

To assist support the framework, posts should be fastened to the concrete that is already there. Metal connectors for connecting posts to concrete by Simpson Strong-Tie are code-approved. To find out the finest techniques for attachment, speak with the building code authority in your area. Lay Composite Trolley Over Concrete Patio

Make sure the decking boards have the correct gapping

For water drainage, for expansion and contraction, and to accommodate the shrinkage typical of wood joist systems, proper gapping is essential. Consider employing concealed fasteners, which, when used with our grooved-edge boards, produce correct gapping.

Hole Pre-Drilling

To prevent breaking or harming the end of your composite boards, pre-drill surface screw holes.

Recognize local ordinances and building codes

Most of the time, obtaining a building permit is necessary before beginning work. Before beginning your project, be sure your deck layout complies with all applicable construction requirements and safety regulations. When requesting a permit, some jurisdictions even demand stamped building plans from engineers.
