← Back to How do I choose permeable paving for farmhouses?

When planning permeable paving for a farmhouse, choosing the right base is crucial for durability and drainage. The underlying requirements depend on the intended use of the area and the expected traffic.
When Is a Sub-Base Necessary?
For light-traffic zones such as garden footpaths, patios, or decorative areas around the house, thoroughly compacted soil can often provide a suitable foundation. This keeps installation simpler and reduces material costs. However, where heavier use is expected—such as driveways, parking spaces, or access routes for larger vehicles—a reinforced sub-base is highly recommended. Options include a concrete layer (typically 7–8 cm for driveways) or a grass-reinforcement grid topped with a thicker resin and aggregate mix. These solutions ensure long-term load resistance and help maintain permeability.
Practical Installation Guidance
The right sub-base structure supports surface drainage and prevents cracking over time. Always begin with a well-cleared, level area. For simple paths, compact the existing soil firmly before applying your resin-bound mix. On driveways, install the recommended sub-base before laying products such as the “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin. This ensures effective water management and a stable, long-wearing surface.
When This Matters Most
- Garden and patio areas: Compacted soil suffices for light use.
- Farm entrances and driveways: A reinforced sub-base is vital for supporting cars or farm machinery and preserving drainage.
