This is how it's done
If you have the spaces between Plant grass pavers you need to fill them with a suitable substrate. One layer is enough on the gravel substructure Clay granules or split, which takes on the function of a drainage and prevents waterlogging.

Preparations
Dig the soil within an area delimited with sticks. The depth depends on the thickness of the lawn paving stones and should be about three times the height of the stone.
Thinner stones are used in the garden, so that the depth here is 15 to 20 centimeters. For driveways and parking spaces, 20 to 30 centimeters are ideal.
The soil must be compacted so that it does not sag from the subsequent load. Edge stones that stand on a concrete foundation serve as a border for the surface.
Substructure
Fill in the area with 16/32 grit crushed stone. After compaction, the distance between the gravel surface and the planned upper edge of the stones is around eleven centimeters. This value is used as a guide for stones that are eight centimeters high. This leaves three centimeters for the leveling layer.
Installation bed
This leveling layer comes directly onto the gravel and serves as drainage. Mix one part lava chippings with one part sand and the excavated Topsoil and pour in the mixture. Compact this layer and smooth the surface. The stones are then laid at a distance of three millimeters from one another.
Fill in spaces:
- Mix the topsoil, sand and clay granules
- Spread the substrate on the surface
- sweep into the honeycomb with a broom
- Tamp down the earth until each honeycomb is three-quarters full
- Fill the gaps up to the top of the stone and water the substrate
Tips
Cut a chipboard so that it fits exactly into the honeycomb. A square piece of wood, which is screwed in the middle, is used to guide the self-made rammer.
Prepare the area
Secure the surface by fastening it with a Plate compactor(€ 359.90 at Amazon *) to edit. In the coming weeks, the substrate will settle, so that the honeycombs may have to be refilled with topsoil. Some flowering plants do not thrive under continuous treading. Wood sorrel, Stonecrop or thyme prefer a lower position. Leave some space between the surface of the earth and the top of the stone. If you would like to green the grass pavers with grass, you should get a special parking lot lawn.
Filling stones
There are special concrete blocks with which the ten by ten centimeter honeycombs can be precisely filled. In this way you get a closed concrete surface that is suitable for driving on. However, the aesthetics leave a lot to be desired and rainwater cannot drain off well.
