Areas of application and selection criteria

Typical uses and points to check before ordering:

• Access roads and courtyards
• Parking spaces as well as pedestrian and cycle paths
• Terraces and garden paths
• Areas where rainwater is to seep into the ground
• Required: approximately 25 stones per m² (calculated)
• Substructure and load-bearing layer designed according to the planned use
• Select jointing material suitable for the drainage joint according to the manufacturer's instructions.
• Secure the edges with a firm border.

Your advantage when buying

According to Diephaus, the stones can be laid mechanically, and the anti-slip device holds the pattern together; if your area requires a greater stone thickness, there is a 10 cm thick version in grey .

What you should pay attention to when making your selection

The joint design, stone thickness and substructure are crucial, as infiltration requires a water-permeable overall structure.

Drainage joint and infiltration

The molded 12 mm spacers create wide joints for surface water; Diephaus does not specify a percolation value in the product information.

Stone thickness and bond

The 8 cm thick paving stone has a 4-fold+ displacement protection system; Keuck also offers a 10 cm thick version.

Deployment and operational limits

Diephaus requires a 3–5 cm thick bedding layer of mineral mixture instead of sand, a load-bearing, frost-proof substructure with a slope and a firm edge edging.
