Impact on Surface Durability
The quality of aggregates significantly impacts the durability of resin-bound gravel surfaces. Hard and clean materials, such as granite or quartz, resist wear and tear over time, making them ideal choices. Softer aggregates can lead to quicker surface degradation, which jeopardises the integrity of the surface.
It’s crucial to ensure that aggregates are clean and dry, as contaminants can weaken resin bonds, increasing the likelihood of defects. Uniform grading and consistent sizes also enhance surface strength by minimising weak points.
Additionally, selecting aggregates with stable mineral compositions helps protect against weather-related damage, ensuring longevity.
Correct Resin-to-Aggregate Ratio
Getting the right resin-to-aggregate ratio is crucial for the durability and performance of resin-bound gravel surfaces. A typical mix consists of 7% resin to 93% aggregate, striking a balance between flexibility and stability to prevent cracking.
For optimal results, the hardener-to-resin ratio should be between 1:1.03 and 1:1.05 to ensure a full-strength cure.
For a mix using around 75kg of 2-5mm aggregates, 25kg of 1-3mm aggregates, and 6.25kg of sand, you’ll maintain good porosity and drainage, allowing water to flow freely.
Straying from this ideal ratio can weaken the driveway, leading to quicker deterioration and a shorter lifespan.
