Resin Bound Surfacing and Resin Bonded Surfacing – The differences

This has to be one of most common questions asked about resin surfaces. So to help your customers make the right choice for their property, we take look at the differences between the two surfacing systems.

The main differences are the thickness that the system is applied, the application method, its appearance and the aggregates used.

Thickness – A resin bound system is applied between 15-25mm thick. The bonded system is applied as a thin veneer of resin and then aggregate on top approximately 5mm thick depending on aggregate size.

Application– Resin Bound is trowel applied. The Bonded system scatters aggregate  on top of wet resin.

Appearance – Resin Bound Systems create a uniform, flat surface. The Bonded System is rough in texture,  taking on the appearance of the aggregate that  sits on top of the resin.

Aggregates– Resin Bound systems use a combination of 2 or more grades of aggregates that are different sizes (2-5mm and 1-3mm). The Bonded system normally uses one size grade of aggregate such as a 1-3mm.

Resin bound surfacing is  permeable

Great for the UK’s ever-changing weather conditions, resin bound is  permeable and SUDS compliant, meeting planning requirements when laid on a suitable base.

As a result, rainfall does not collect into large puddles or pools, but simply runs into the ground or nearest storm drain, making it a great solution for not only driveways, but also outside entertainment spaces and swimming pool surrounds.

Resin bonded surfacing is non-permeable

For customers who don’t require a water permeable solution, the resin bonded surface is a cost effective way to transform a property’s outside space. From creating modern landscaping to smart vehicle parking, a resin bonded surface provides an attractive, non-permeable, non-slip coloured solution.

Will a customer require planning permission for resin bound surfacing?

Due to the increased risk of flooding caused by increased urbanisation, all new driveways have to comply with SUDS regulations, (Sustainable Urban Drainage System).

Resin bound is SUDS compliant meaning it does not require planning permission providing the sub base on which it is laid is porous or a suitable soakaway exists.

Resin bound can be laid on special concrete or open textured macadam on top of a type 3 stone. The system can be laid directly on top of old macadam or concrete but suitable soakaways or drainage flow must be present.

The System can handle up to 850L of water per m2 per minute.


Resin Pathway

How long does it take to install?

With no need for excavation works, the installation process does not require any commercial digging equipment. As a result noise pollution is reduced and disruption to the homeowner is kept to a minimum.

Once the area has been prepared and cleared of any debris, the new surface will be laid against a secure stable edge or edging. So provided the weather stays dry and the temperature does not fall below zero, a resin bound specialist should have no problem finishing the work in only a few days.

The resin bound system must be allowed to cure and during the curing period no disturbance or trafficking is permitted and the surface should be protected from rain.

When fully installed, the new resin bound surfacing or resin bonded area should be able to take vehicle traffic after around thirty-six hours.

How easy is it to take care of the surface?

Unlike traditional tarmac which can quickly become tired and weathered, a resin bound surface is easy to maintain and resistant to unsightly weeds. However in order to keep the surface in tip top condition, the homeowner should regularly brush their surface clear of any dirt, pick up any fallen leaves, and remove any growing weeds gently by hand.

So whether a homeowner is looking for a permeable driveway or a coloured decorative resin bound outside space, by understanding the difference between the two surface types, a customer can decide on the best solution for their property.
