Over A Balcony Composite Decking Installation Instructions

Must read

Any way you look at it, composite decking will improve your home’s outside living space. Composite decking will provide you with beautiful outdoor afternoons for years to come, whether you live in a residential building, a suburban home, or on a rural property. It won’t really matter what level your composite decking is located at. The majority of individuals are overjoyed to have them put at ground level. However, others claim that the greatest way to appreciate composite decking is from a height.

Because of this, we explain in this post how to construct composite decking over a balcony. Let’s raise your platform so you can sit back in your preferred composite decking chair and take in the scenery from a vantage point!

But before we begin…

It’s likely that the flooring beneath your tiled balcony has already been waterproofed if you plan to build composite decking over it.

Technically, you could build your composite decking right on top of it, but we don’t recommend it. Because it’s not a good idea to drill through a slab to anchor your battens, you should avoid doing so at all costs. Doing so might undermine the integrity of your waterproofing and result in waterlogging and other irreparable harm to the structural elements of the floor tiles balcony.

In order to obtain the greatest results for your composite decking, we will explain how to put your floor tiles balcony (tiled or not) in order to prevent this.

How to build composite decking over a balcony

Use a tape measure to check that there is sufficient room between your current floor tiles balcony and the height at which you want your composite decking to be placed. Generally speaking, you need at least a 50mm space for aluminum joists and a 60mm clearance for wood joists.

Tape measure 

Utilize the tape measure once more. The width of the golvplattor balkong you plan to install should be measured. As that is the factory default, you’ll generally find that they are between 19 and 20 millimeters wide, however, there are some wider planks that are 25 millimeters wide.


Determine how much packing material you’ll need in order to get your composite decking to the right height. Generally speaking, thicker joists are preferable since they can cover greater distances, but you must make sure there is at least 10mm of space between them and the substrate.

As we have explained, it’s not a good idea to drill into your slab to secure your joists to the concrete since it might impair your waterproofing.



The joists must still be fastened to something sturdy in order to prevent them from bending and bouncing beneath your feet. A builder’s pedestal foot will be useful in this situation. With the help of this clever tool, you can place joists over a surface without really fastening them to it. Without the need to drill into the surface, each Pedestal Foot may adhere to it. Purchase a lot of these tools from your neighborhood hardware shop for tradies (or search online for any you want to use); overorder so you won’t run out in the middle of your job; return any extras. Just be sure to verify the business’s return policies beforehand.

When you go home from the store, determine the spacing between your joists, and mark it on the slab. 1.5 meters is a reasonable spacing to leave between each length of wood. Even closer installation is possible, but Pedestal Feet may be pricey, so the less you need to purchase, the better.


Attach the builder’s pedestal feet to the predetermined locations using your preferred outdoor grade glue (we suggest Sikaflex). Before setting them down, make sure they’re in the appropriate spot and in a straight line. To ensure that each Foot is well secured in place, let the glue dry.

Go around to each pedestal when the glue has dried and adjust each one to the desired height minus the thickness of your joists and composite decking. After adjusting each one, use a laser level or a traditional 2m spirit level to make sure they are all at the same level.

Once the Pedestals’ Feet are all level, install your joists over top of them and screw them in place, making sure they are securely fastened and have no space to budge.

The next step is to use plastic packers to fill the space between the pedestal and any springs in the joists or battens.


Make sure the entire structure is level by using your level to go over it. When using your floor tiles balcony, you shouldn’t feel like you’re walking on a trampoline, therefore check each individual joist to make sure it doesn’t bounce.

It’s time to cover that unfinished structure you just built with your lovely composite decking planks, and there you have it! Your raised komposittrall is all finished.

Last words

It’s time to start having fun after you’ve constructed your floor tiles balcony by following the preceding procedures. Set up a shade over your heads, spread out some deck chairs, fire up the grill, and invite some friends over. It’s time to take advantage of those days spent outside on your ideal platform made of composite decking!
