To achieve a smooth and level surface for your resin-bound gravel installation, it’s crucial to choose the right leveling compound. Ardex K301 is a solid option, though it can be pricey; it performs well in outdoor applications. Additionally, ensure that the concrete or tarmac base is strong enough for the intended use. The chosen sub-base should be prepared with a depth that ensures stability and drainage, as proper sub-base preparation is essential for long-lasting results. Epoxy resin compounds are versatile and suitable for priming and filling any imperfections. Cempolay Ultra and Flow Top are reliable choices for preparing surfaces, especially outdoors. For uneven areas, Site Mix Granolithic Concrete provides a strong solution. When considering costs, balance the benefits of durability with the initial expenditure. Each compound has distinct properties that influence performance, so ensure your choice matches the specific challenges of your site for the best results.

Layer Thickness Control

Achieving the correct layer thickness is crucial for a successful resin-bound gravel installation, particularly on uneven surfaces. Consistent depth measurement ensures durability and prevents cracking. Here are the guidelines for ideal aggregate selection and thickness control:

Layer Type Recommended Thickness
Driveways At least 18mm
Footpaths Minimum 15mm
Unstable Areas 30–40mm
Standard Aggregate 18mm (3x aggregate)
Risks of Thin Layers Cracking, failure

Use depth gauges or screed rails during installation to maintain uniformity within ±2mm. Address ground irregularities by filling low spots and smoothing out high areas. Ensuring proper layer thickness not only boosts strength but also enhances overall performance and longevity.

Handling Slopes and Gradients
