Substrate Preparation for Resin Bound Paving: Key Steps & Guidance

← Back to What is the price of resin bound paving?

Preparing the underlying substrate is a crucial first step for a successful resin bound paving installation. The right approach sets the foundation for a durable, permeable, and attractive outdoor surface.

Assessing and Choosing the Right Substrate

The most suitable substrate for resin bound paving is usually stable, level, and free from loose material. Concrete and well-compacted asphalt are preferred bases, as they provide a firm, load-bearing surface capable of supporting the resin system. Before any work begins, inspect the area for cracks, crumbling sections, or signs of inadequate drainage.

Concrete: Should be clean, dry, and sufficiently cured (ideally at least 28 days old).
Asphalt: Ensure it is well-compacted and not prone to movement.
Existing surfaces: Remove unstable materials like loose gravel or deteriorated substrates.

Surface Cleaning and Priming

Any substrate chosen must be thoroughly cleaned before resin application. Remove dust, dirt, organic matter, and oils, as these can hinder adhesion. For absorbent surfaces like concrete, a suitable primer such as Resinstone can provide enhanced sealing and mechanical strength, further supporting the resin system.

Ensuring Proper Drainage

Effective drainage is vital for resin bound surfaces. Make sure the substrate has a gentle fall to allow surface water to escape naturally. If puddling or poor run-off is common, consider installing a permeable system such as the Flowstone Complete Kit. This not only helps with water management but also prolongs the life of your new paving.

When Substrate Preparation Matters Most

Proper substrate preparation is especially important in areas with heavy foot or vehicle traffic, or where the ground is prone to movement or moisture. A well-prepared base minimises the risk of future problems like cracking, delamination, or water pooling.
