Resin Bound vs Resin Bonded

 

What's The Difference between Resin Bound and Resin Bonded Paving

Although they may sound like the same thing, Resin Bound Paving and Resin Bonded Paving are two very different systems with different application methods and properties. However, they are still essentially a method for creating durable surfacing using a combination of resin and natural stone aggregates.

 

What is Resin Bound Surfacing.

Application of Resin Bound 

Resin bound surfacing is created by mixing the resin with the aggregate prior to application to the base. This Resin and stone mixture is the spread over the base using a squeegee before being trowelled out to a completely smooth finish. The installation of a resin bound surface is quick, and can be walked on after just a few hours.  Resin bound surfaces a typically applied at anywhere from 12mm to 24mm dependant on their desired usage.

A Resin Bound Driveway or path will have a smooth level finish that has a glossy wet look gravel. Such driveways look beautiful in any surrounding and can be installed in a wide range of colours and materials. 

Properties Resin Bound Gravel Systems

Resin Bound Paving is extremely durable and can be expected to last in excess of 25 years. Requiring very little maintenance a resin bound driveway can be kept looking like new by simply sweeping and occasional washing with a mild detergent.

Resin Bound Systems are fully permeable allowing surface water to freely pass through the system. These surfaces conform to the governments SUDs regulations, replicating the drainage patterns of natural systems with minimal environmental impact.

Resin Bound Driveways have a smooth level surface whilst retaining some limited flexibility so are resistant to cracking. There are no loose stones with a resin bound system preventing stone from being kicked up into flowerbeds or walked through your property. Such surfaces are anti-slip and friction can be increased with the addition of crushed glass to the mixture. 

 

What is Resin Bonded Surfacing.

Application of Resin Bonded

Resin bonded surfacing is created by applying a thin coat of resin to a suitable base before loose gravel is cast or scattered over the resin before being left to cure. Once the resin has cured all loose stone is swept away leaving a layer of aggregate bonded in the resin. A resin bonded system has a depth governed by the size of the aggregate used. A 1-3mm aggregate will typically have a depth of around 4mm. It is necessary to ensure that the base is as sound and levelled as possible. It must be monolithic or composite whole like concrete. The base of such surface must be free of grease, standing water and loose material. Thus, by preparing the base perfectly you can ensure that the resin bonds perfectly. The resin used in our driveways cures very quickly and can withstand traffic within hours. It is always advisable to call in a specialist company that give you a guarantee for works undertaken.

A resin bonded driveway will not be as smooth or glossy as a resin bound sytems but so long as the base is level so to will the top coat of gravel.

Availble in many colours of natural stone aggregate Resin Bonded Driveways can be created to compliment their environment and the surrounding area.

Properties of Resin Bonded Gravel

Resin bonded surfaces are again very durable and will typically last as long as the sub base remains sound. Resin Bonded Driveways are not permeable like resin bound systems. Resin Bonded Gravel has a very high friction coefficient so are ideal for non-slip surfaces. Again after the initial loose stones have been removed after application any remaining aggregate is firmly bonded in place, so there is no loose gravel to be kicked around. 

 

Summary

In summary both resin bound and resin bonded systems can be used in a variety of applications and can be installed in a wide range of colours. Both are suitable for driveways, paths, patios, cycle lanes, and carparks to name just a few scenarios, and both can handle heavy traffic such as busses etc. Both systems are suitable for use in both commercial and residential application. 

The primary differences are that a resin bound surface is fully permeable and has a smoother glossier more modern appearance, where as a resin bonded surface in non-permeable and has a rougher appearance more similar to that of loose gravel.

The popularity of Resin Bound Driveways has been increasing considerably over the last few years due to their modern, sleek appearance and their low maintenance requirements.
