Multidal

Step 1: Excavation

Perform the necessary excavation works. Always remove the topsoil. The bearing capacity of this layer must be at least 20 Mpa.

Step 2: Borders

Install the borders. These should extend 2 cm above the level of the top of the plate.

Step 3: Foundation (only for vehicular applications)

Place the foundations/sub-foundation at a depth of at least 25 cm. MWork in layers of 20 cm at the most, and compact with a plate compactor. The foundation may consist of limestone rubble, porphyry rubble, or crushed concrete rubble (chip size: 0-32 mm or 0-40 mm).

Step 4: Levelling layer

Place the leveling layer in fine gravel, compact and level. Add the fine gravel, compact and level. The depth of the levelling layer for vehicular applications must be 5 cm, for non-vehicular applications 15 cm. The levelling layer may consist of limestone or porphyry (chip size: 2-4 mm, 1-3 mm, or 0-4 mm) or sieved sand.

Step 5: Multidal

a. Place the first Multidal parallel to the border.

b. Thanks to the new connection system, you easily connect the next grid. You can also disconnect it again, if necessary.

c. We recommend laying the grids in stretcher bond. Start the second row with half a grid, the Multidal is easily cut with a disk cutter.

d. The third row starts with a full grid. Repeat the previous steps and finish the entire area in this way.

Step 6: Gravel

Add the gravel. It is not recommended to drive on unfilled grids. Level with a shovel, brush, rake, and squeegee. Do not compact the ornamental gravel. Allow the gravel to exceed the grids by 1 to 2 cm (1cm for finer and 2 cm for coarser types of gravel). Due to natural compaction, the gravel will still slightly settle. Eventually, there should be just enough gravel to hide the Multidal.

Additional advice

It is not recommended to use brick rubble as a foundation, as it pulverizes over time. For vehicular applications, we recommend a size of 8 to 25 mm (smaller gravel types will stick in the wheels). For non-vehicular applications , we recommend a size of 4 to 25 mm (smaller gravel types will eventually pulverize).

Step 1: Excavation

Perform the necessary excavation works. Always remove the topsoil. The bearing capacity of this layer must be at least 20 Mpa.

Step 2: Borders

Place the borders. They should extend 2 cm above the level of the top of the grid.

Step 3: Foundation (only for vehicular applications)

Create a foundation layer at least 25 cm deep. Use a foundation substrate, which provides both a stable base and nutrients. Afterward, apply weight to the compacted foundation (e.g. with a heavy roller).

Step 4: Bedding layer

Lay the bedding layer using bedding substrate. For vehicle applications, the bedding layer should be 5 cm deep. For non-vehicle applications, where no foundation layer is used, this depth should be 15 cm.

a. Place the first Multidal parallel to the border.

b. Thanks to the new connection system, you easily connect the next grid. You can also disconnect it again, if necessary.

c. We recommend laying the grids in stretcher bond. Then start the second row with half a grid, the Multidal is easily cut with a disk cutter.

d. Start the third row start with a full grid again. Repeat the previous steps and finish the entire area in this way.

Step 6: Grass grid substrate

Fill the ECCOdal grass grids with substrate up to 1 cm (max. 0.5 cm) below the edge of the grid. Use grass grid substrate and brush it thoroughly to distribute it evenly and avoid gaps. This ensures a smooth and uniform surface.
Tip: Never fill the grass grids with only topsoil. Topsoil can compact too much, preventing grass seed from germinating.

Step 7: Sowing

Sow the grass in Multidal.

Step 8: Waiting period

After 6 to 8 weeks, you can start using the grass parking. If the parking area will be heavily used, we recommend waiting 16 weeks to allow the grass to grow densely. Mowing can be done during this period.
