Permeable Resin Bound Surfaces: How to Ensure Drainage

Permeable Solution for Resin Bound Gravel Surfaces

Looking for a practical solution to create a hard surface that also lets water drain away? Permeable resin bound gravel systems offer just that—sustainable, attractive, and compliant solutions for outdoor paths, patios, and driveways in the UK climate.

What Makes a Resin Bound Surface Permeable?

Permeability in resin bound gravel surfaces comes from the unique method of thoroughly mixing clean, dry aggregates with specialised resin binders before laying. This combination creates a strong, yet open matrix that allows water to pass through the entire depth of the surface—reducing puddling and aiding sustainable drainage (SuDS) compliance.

For best results, binder choice is crucial. For example, a non-yellowing polyurethane binder is recommended for white aggregates, while a low-yellowing epoxy binder is ideal for coloured stones, maintaining colour and strength without impeding water flow.

Selecting a Suitable Permeable Kit

Choosing the right kit depends on your intended finish, aggregate type, and surface size. Flowstone Complete Kit includes all materials needed and helpful instructions, making it easy to create either decorative paths or robust driveways. For bespoke installations, pair your chosen aggregate with the best binder: opt for Polirock polyurethane with white stones, or Trasparente epoxy for colourful or dark stones.

Ensure aggregates are clean and dry before mixing with the resin.
Only mix as much as you can lay within the resin’s working time.

When Permeability Matters Most

Permeable resin bound surfaces are invaluable where water pooling is a concern or when aiming to meet planning requirements for drainage. They are ideal for driveways, footpaths, and patios, helping protect your property’s foundations and the surrounding environment by managing rainwater effectively.
