Paving stones can be laid on concrete

Lay the pavement correctly

Pavement construction

  • Sub-construction plan
  • Frost protection layer: 30-70 cm compressed, depending on local conditions and load, gravel, grain size approx. 0-63 mm
  • Fine level: 10 cm compacted, gravel, grain size approx. 0 - 31.2 mm
  • Side edging
  • Bedding: apply approx. 4-6 cm (later compacts to 3-5 cm), washed crushed sand / grit mixture, grain size 2-8 mm
  • Paving stones: choose stone thickness and stone length depending on the load
  • Sanding in and shaking off

With this symbol you will find tips for heavily used surfaces.
We speak of heavily used areas when frequent dynamic load changes and / or high loads in small turning or turning radii are to be expected. Heavily sloping surfaces (e.g. inclines) increase the stress additionally. The relevant standard for work contracts is ÖNORM B 2214 for paving work. We also recommend applying the guidelines RVS 08.18.01 and RVS 03.08.63.

What you need for paving:

Gravel approx. 0-63 mm for the frost protection layer according to the guidelines mentioned above.
Gravel approx. 0-31.2 mm for the fine grading according to the guidelines mentioned above.
Washed crushed sand / grit mixture 2-8 mm for the bedding.
Weissenböck joint sand (crushed sand / grit mixture 0-4 mm from dolomite crushed stone) and paving stones; Edge and possibly step stones, if necessary pavement drain concrete for bound areas.
Shovel, disc chest, 2 shaped tubes 4000/40/40 mm, broom, cord, aluminum lath, construction bracket, spirit level; possibly imprint-free plastic hammer for curb and step stones, sufficiently long hose with shower attachment, water connection.
Heavy vibratory plate for compaction of the base course. Use vibratory plates> 400 kg for car loads, for base courses for regular truck loads use vibratory road rollers (for the final final compaction on the surface of the paving stones use vibratory plates> 250 kg for car loads and> 400 kg for truck loads, each with Plastic sliding plate), stone splitter.
A working temperature of at least +5 degrees Celsius for several days (laying on frozen surfaces or with frozen materials is not permitted).

Excavation, frost protection layer and fine leveling:

The excavation should be approx. 30 cm wider than the final paved area. A slope of 2% must be taken into account for surface drainage in the sub-structure (excavation floor). The sub-base (excavation floor) must be compacted in a stable manner (e.g. with a vibratory roller). In the case of loam and mixed soils in the subsoil (= cohesive and non-cohesive soil mixed), a fleece is to be laid on the excavated floor in order to prevent later frost elevations and non-solidification due to ridge blockages, which make the ridge watertight, and to prevent lateral drainage via a longitudinal to ensure the installed drainage pipe by surrounding it with drainage gravel and filter fleece. Bring in ballast 0-63 mm in layers and compact e.g. with a vibrating roller (max. 20 cm per layer!). The thickness of this frost protection layer should be 30 - 70 cm, depending on the local conditions and the load on the surface (frost depth), and must be on the upper side on the slope of the paved surface. An approx. 10 cm thick fine level of 0-16 mm gravel is applied and compacted well, e.g. with a vibrating roller or a heavy vibrating plate. The surface should be closed in a filter-stable manner with respect to the subsequent bedding material. Filter-stable means that the bedding sand does not trickle into the base course or is washed in by water. The fine level must be made exactly to +/- 1 cm so that the sand bed has an approximately the same thickness of max. +/- 1 cm and uneven subsidence is avoided (control using an aluminum lath; final height of the pavement = frost protection layer + fine level + sand bed + Pavement - 1 cm compression dimension of the bedding). You should therefore allow at least 1.5 cm overhang of the upper edge of the surface in relation to built-in components such as manhole covers, etc., before shaking, or 2-8 mm for washed crushed sand / grit mixture. This elevation is reduced to less than 5 mm by shaking and re-compacting the bedding.

You can considerably increase the resilience and durability of a paved surface if you make use of the arching effect and form the paved surface in the shape of a vault. The effect is that mainly compressive stresses occur in the surface, which the construction can absorb more easily than tensile stresses. This type of construction requires a vault formation from the upper edge of the existing subsurface, i.e. H. all base layers, bedding and stones.

Side edging:

Flower bed edging stones Palisades Pave Edge

A border on the side ensures that the paving stones do not migrate at the edge. It is ideally made in a matching design with Cotta blocks (natural or antique), Tegula bricks, Forum Mini or Rondo palisades or bedding stones. All four systems offer enough height for the adjacent lawn so that it does not wither. Put the stones in a dug trench in pavement drain concrete 10-20 cm high. Alternatively, you can also nail the Pave Edge perimeter rails directly into the fine level and the substructure.

Production of the bedding:

Place the shaped pipes on the fine level and fill them in between with the bedding material. Then pull the aluminum batten over the shaped tubes to create a uniformly strong, height-accurate bedding. After removing the shaped tubes, fill the resulting cavity with the bedding material. Neither compact nor step on the finished bedding. Do not make bedding larger than you can lay paving stones in a day. Important: only use low-lime (prevents settlement and efflorescence), washed (prevents frost damage) and graded material (is filter-stable against trickling or washing of the joint sand into the sand bed)!

Laying paving stones:

Start in a corner - if possible at the lowest point of the surface and at a right angle. Tension a cord for flush installation. Now lay the paving stones in front of you (= from the laid area) without stepping on the sand bed.
Lay square or maximally rectangular formats with an aspect ratio of W: L = 2:
