Paver Stabilisation

To ensure optimal stabilisation of your paving stones, the bedding (or sub-base) must meet the following minimum requirements:

• Allow for drainage of rainwater and runoff. Example: your soil can be considered well-drained if there is never any standing water after heavy rain. If this is not the case, it is recommended that you drain the surface either by installing drains in the ground or by creating a drainage layer with 40/80 crushed stone.
• Not be subject to rising groundwater. Example: your ground is subject to rising groundwater if, after a long period of rain, it becomes damp and unstable.
• Have sufficient load-bearing capacity for the intended use (pedestrian or vehicle traffic). Example: a site can be considered stabilised when it has been driven on for several years. In the case of a new house, it is advisable to check the condition of the ground with the earthworks company.
• Have no unevenness greater than 1 cm over 3 m.

If in doubt, it is best to check with an earthworks company.

Installation on slopes up to 10% is possible. The installation must be carried out against a concrete kerb at the bottom.

Before installing our stabilisation slab for paving stones, it is important and mandatory to prepare the ground according to the intended use.

For a pedestrian walkway :

1. Dig out 10 cm of soil.
2. Compact the surface using a lawn roller to optimise the levelling of the ground. If there are any large stones remaining, remove them by hand.
3. Unroll a 120g/m² geotextile. For perfect coverage, overlap the geotextile strips by 10 cm.

For a driveway :

1. Dig out the soil to a depth of 20 to 30 cm.
2. Compact using a vibrating plate to ensure the ground is level.
3. Unroll a first 120g/m² geotextile. For perfect coverage, overlap the geotextile strips by 10 cm.
4. Create a 10 to 20 cm foundation layer consisting of a mixture of 70% 30/60 gravel and 30% sand.
5. Compact using a vibrating plate.
6. Roll out another 120g/m² geotextile.

Our paving stone stabiliser is suitable for all concrete paving stones measuring 15 x 15 cm and 6 cm high. We also allow stone or sandstone paving stones, even though they are less common because they are more expensive.

We recommend choosing paving stones with smooth sides without protrusions. The paving stones must not be aged. Often when they are aged, they have been tapped and have irregularities. This makes them unique and attractive but uneven. Using this type of paving stone would make installation and traffic on our paving stone stabilisers unstable.

The manufacturing tolerance according to standard NF EN 1338 is +/-3mm on the 150 mm side.

This type of paving stone is easily found in DIY superstores or building material suppliers.
