Instructions for laying natural stone slabs

Laying natural stone slabs is not very difficult. The plates can be fixed to the substrate with mortar and fixed or placed loosely in a gravel bed. In both variants, the instructions for the correct procedure must pay particular attention to evenness and frost prevention. Pre-sort with polygonal or polygon panels.

Open or closed joints

One of the most popular garden path design consists of polygonal natural stone slabs. They are put together at random and the unevenness fits perfectly into the natural environment. The natural stone slabs can be loosely laid without mortar or laid on fixed to concrete. Verf Grouting the natural stone slabs is urgently recommended in the case of a concrete foundation, in order to exclude scouring and under-rinsing. When laying the natural stone slabs in the chip bed, the joints can remain empty and contribute to good drainage.

Laying natural stone slabs

Gravel, crushed stone and gravel or

    • Concrete and bedding mortar
    • Natural stone slabs
    • Possibly curbs
    • Compressor (vibrator, rammer, roller)
    • Spirit level
    • Rubber mallet
    • Working gloves
    • Possibly cement cleaner
    • 1. Excavation

Lift the substrate for the Location of the natural stone slabs so deep that the thickness of the plates and the underground mounting have space. To calculate the thickness, calculate a filling height of about ten centimeters for a gravel bed and about five centimeters for a concrete foundation. Verd 2. Compacting

In any case compact the soil with several treatment passes with a vibrator, a rammer or a roller.

3. Mortar and / or Sludge

When casting a concrete or mortar foundation, apply a two-centimeter thick layer of sand to the compacted substrate. Work with sludge that is less viscous than normal mortar.

4. Possibly set curbs

5. Pre-sort slabs

Prior to that, roughly lay out the pattern or mosaic of the natural stones so that the individual shapes fit together later.

6. Arrange and tap plates

Place the plates close to the sides of your work surface. When laying, consider that you need to get away from the house and realize a gap of about two percent. Check the progress with the spirit level.

7. Possibly grout

Depending on the type of construction and your wish, you have the spaces between them. With the variants left open, half a load of sand helps to delay rinse-off rinse.

Tips & TricksThe most important recipe for success is preventing any cavity beneath the plates. Compact and prevent these "blasting chambers" when entering water freezes.
