Choosing the right substrate is essential for a durable and effective permeable resin system. This guide covers whether you can install resin-bound or resin-sealed surfaces on compacted soil, concrete, or both, helping you select the best approach for your outdoor project.
Substrate Options: Soil vs Concrete
Permeable resin systems can be installed on different bases depending on your site and traffic needs. For light-use spaces such as garden paths or patios, systems like the Flowstone Complete Kit are suitable for application over well-compacted soil, offering natural drainage and a strong, attractive finish. However, for areas expecting heavier vehicle traffic, a reinforced base—such as concrete or a stabilising grid—is highly recommended to ensure long-term durability and prevent surface movement.
When Is Concrete or an Absorbent Base Required?
Some resin sealants, such as Resinstone, are designed specifically for use on concrete or other absorbent, hard surfaces. These products provide waterproofing and surface protection, but are not suitable for loose aggregate or bare soil. If you’re resurfacing a driveway or car park, using a concrete base beneath the resin layer provides additional strength and stability, particularly important for frequent or heavy vehicle use.
When This Matters
It is important to match your substrate and resin system to the expected use. Lightweight options on compacted soil are ideal for paths and patios, while heavy-duty spaces should always be built on a solid, stable base. Taking time to prepare the correct substrate prevents costly repairs and ensures lasting results.
