Can Resin Systems Be Installed on Soil or Concrete Bases?

← Back to How much resin do I need for a courtyard?

Choosing the right base for your resin floor is essential for a durable and attractive finish, especially in outdoor spaces like courtyards, patios, and driveways. Understanding whether to use compacted soil or concrete as your foundation will help ensure your new resin-bound surface meets your needs and stands the test of time.

Installing Resin on Compacted Soil

For light-use areas such as garden paths, decorative spaces, or pedestrian courtyards, it’s possible to apply a resin-bonded stone system directly onto firm, well-compacted soil. Generally, a layer around 2cm thick is sufficient if the ground is stable and properly levelled. This approach can be a cost-effective solution where vehicular traffic isn’t expected, offering good water drainage and natural integration with landscaping. However, take care to thoroughly compact and level the soil before application to prevent future settling or cracking.

Concrete Bases for Heavy Duty and Vehicle Access

If you plan for heavier use, such as regular foot traffic, parking spaces, or access for vehicles, a concrete base is strongly recommended. A reinforced concrete slab—typically 7–8cm thick—provides the strength and stability needed for lasting results. This method also allows for a smoother, even finish and minimises the risk of cracks or movement under load. For permeable resin-bound surfaces, you can use a specialised grid or drainage layer above the concrete base to allow water to pass through while maintaining structural support.

Practical Tips for Choosing the Right Base

• Assess usage: Choose resin over compacted soil for paths and decorative zones only. Opt for concrete if heavy loads or cars will use the area.
• Surface preparation: Whichever base you use, ensure it is level, dry, and free from debris before starting the resin installation.
• Pick suitable materials: Kits like the Flowstone Complete Permeable Floor Kit offer guidance on both application and base type for outdoor spaces.

When This Matters

Selecting the right base is particularly important if you’re installing resin surfaces in a mixed-use courtyard, a driveway, or areas where longevity and safety are priorities. The base affects everything from water drainage to long-term maintenance.
