Concrete paving stones as a terrace covering offer many advantages. The great dimensional accuracy of the individual formats is probably the greatest of them, because she is the reason, why even moderately talented do-it-yourselfers can achieve respectable plaster results. In addition, concrete blocks are many times cheaper than natural stones
The color of concrete paving stones, on the other hand, is a problem. In the different regions of Germany, the manufacturers use different additives for the coloring, so that a "jura yellow" in the north of the republic comes across as slightly pink, while in the Rhineland a stone with the same designation is bright yellow. You should therefore always ask your supplier to show you color samples, sometimes in larger quantities. The same also applies to concrete block steps, coming from the same program. These block steps, which are actually intended for stairs in the garden, can be used as finishing stones for the paved surface. Attention: A single step with the format of 15x30x100 cm weighs around 110 kg. So you need at least one strong helper, who places and aligns the steps with you.
You can do the rest yourself. Compacting and removing sand beds and laying stones requires more skill than strength. It is cheap, sprinkle enough cement on top of the leveled sand and only then lay the stones. By grouting the joints later, a stable lean mortar mixture is created.
1 Die Blockstufen legen Sie entlang den senkrechten Gehwegplatten auf das Bett aus Sand und Magerbeton. You need a slight incline towards the drain channel. Leave them about 2 cm overhang the panels.
2 Beim waagerechten Ausrichten der Stufen in Längsrichtung helfen Ihnen kleine Holzkeile, which you between levels and . slide plates. The steps are cut with a two-hand cut-off grinder.
3 Die überstehenden Fliesen an der Terrassentür schlagen Sie bündig mit der Hauswand ab. They will later be pasted over with natural stone slabs.
4 Sind die Stufen gesetzt, compact the sand bed with a small vibrator to lay the paving stones. At least stick with it 20 cm away from the installed block steps.
5 Über zwei Alu-Abziehleisten ziehen Sie den Sand mit dem Richtscheit ab. The aluminum strips are already included 2 % gradient relocated. Only when laying the stones do you remove them again.
6 Streuen Sie trockenen Zement satt auf die Sandbettoberfläche. The leveled surface must not become uneven again as a result.
7 Pflastersteine in drei Formaten verlegen Sie zu einem „wilden“ Verband. Always work from the laid area.
