How to lay your balcony slabs on pedestals


The slabs for the balcony cover the raw screed and beautify the outside seat. Natural stones have the advantage that they are very easy to care for and make the balcony look clean and tidy. In addition, they withstand many years and become even more beautiful with natural patination. But before that is still laying the balcony slabs: We give you a simple guide to the clean occupied balcony floor.

Calculate plate quantity: That's how it works!

First, calculate how many balcony slabs you need at all. For this you need the square footage of your balcony, which you add 5 - 10% offcuts. In this way, you can break a record in between, without causing much annoyance.

Add about 2 to 3 millimeters of side to the individual balcony slab to allow for the joints. Then divide the calculated balcony area by the area of ​​a tile, the result is the number of tiles.

Which and how many pedestals do I need?

For up to 40 x 40 cm balcony slabs you need pedestal bearings that have a bearing diameter of 12.5 cm. Larger plates up to 50 x 50 cm are placed on 15.0 cm pedestals.

Remember that you need center, edge and corner bearings for each tile. Overall, there will be about 25% more bearings than plates. If there are no joint crossings installed in the pedestals you must also buy these.

1. Prepare underground

Make a clean, level and stable surface. Remove all old flooring residue and fill all holes and cracks. Reinvigorate larger cracks so they do not rupture and transfer tension to the tiles.

Make sure that your balcony has a slope between 1 and 2% away from the house wall so that the rainwater can drain off. If this is not the case, you must definitely repair before laying the balcony slabs.

2. Perform balcony sealing

Now seal the substrate cleanly against penetrating water. For this purpose, a mineral Dichtschlämme, bitumen, special film or liquid plastic are suitable.

3. Lay balcony slabs on pedestal bearings

Now lay each balcony plate on the associated pedestal storage. If your pedestals have a thread, make sure that all bearings are the same height and the balcony slope is maintained. Use the crosshairs for even distances.

Tips & Tricks

If possible, you should only lay cut balcony slabs in marginal areas with little traffic, as these are particularly susceptible to breakage. A balcony covering on pedestals is not as stable as one on the ground. But the drainage works more reliable.
