Like resin bound surfaces, a huge range of coloured aggregates are available, making it easy to create a distinct surface to suit any number of decorative purposes. The main consideration to make with these surfaces is their impermeability. Coloured crushed glass can also be laid for an especially highly decorative finish. Both systems use resin and aggregates to form fixed surfaces, but the differences are numerous.
Concrete must be allowed to dry sufficiently to prevent blistering of the resin caused by moisture vapour pressure; surface relative humidity ≤ 75% is an indication that the concrete is sufficiently dry. Similarly, the free volatiles in asphalt or asphalt concrete must be allowed to evaporate to avoid blistering. A waiting time of 3 weeks in warm or mild weather, longer in cold weather, is typically sufficient. All ronacrete products for resin bound surfacing or tree pit applications are uv stable. When retention of the original colour is required, uv stable resins should be chosen. A typical argument put forward by suppliers who do not offer uv stable resins is that many of the aggregates available are yellow and/ or brown.
It is often preferred for traditional and historic looking properties where the modern look of resin bound would not fit. Resin Bound Driveways The finished surface has a textured feel and provides high levels of grip, ideal for areas such as disabled ramps. It is a durable finish suitable even for areas with light vehicle traffic. However, the bonded system is not permeable so there needs to be drainage in place, and over time excessive wear may loosened some stones from the surface causing bald patches. The textured finish allows for fantastic traction on the road, creating a safe surface for high traffic roadways, and is commonly used at junctions and on the approach to hazards.
There are two different systems that use resin to fix gravel aggregates to create decorative surfacing. These are resin bound porous paving (such as our bba approved addaset,addabound and terrabound range and terrabase rustic 'minimum-dig' paving system) and resin bonded paving . This system provides a loose gravel effect in appearance without the common trouble of stone migrating along paths and into houses. Available with a 2-5mm or a 1-3mm sized aggregate, this system offers a high friction finish suitable for patio, paths and driveways. The traction provided by the bonded aggregate makes this system also a great choice for disabled ramps and steep driveways. One advantage of the resin bonded system is that it looks and feels like loose gravel without migrating stone.

This page will take you through the key differences between resin bound and resin bonded systems. This system involves applying a film of resin to the surface, on top of which clean, dry aggregate is scattered; completely covering the resin. The size of stone used in the resin bonded system ranges from 1mm to 6mm. The thin, impermeable, single stone layer tends to have a rougher more textured finish. Resins used for resin bonded surfacing are typically based on two component polyurethane, methyl methacrylate or bitumen extended epoxy technology; all having their own benefits. It should be noted that the flexibility of bitumen extenders may be reduced in the long term, affecting the performance of the surfacing. All resins require some delay before application to new concrete, asphalt and asphalt concrete substrates.
