Are Polyester Resins Suitable For Resin Bound Driveways?

When the time comes to replace your old driveway or design a new one, you will want to ensure that you have chosen the very best materials. You want your driveway to look great, to last many years and to be straightforward to lay and maintain. The best material for achieving these goals is resin bound - but there is good resin bound and not so good resin bound.

This comes down to the type of resin and making sure you know what’s best. It could make all the difference. So do you choose polyester or epoxy resin and why? It's time to find out...

What Is A Resin Bound Driveway?

Your driveway could be made from concrete, asphalt, gravel or paving stones - or you can go for something that is new, exciting and long lasting such as resin bound. This material is a mixture of resin and aggregate (stone) that has been carefully mixed so that all of the stone is coated in the resin.

This mix is then pressed onto an asphalt base that has in turn, been laid on a hard core base for good drainage.

You can choose any type of aggregate that you want and in any colour that you want. In fact, the mixture can even be dyed to the exact shade you have in mind to match with your home or to offset your garden design. 

The driveway is laid in one continuous section, so there are no cracks or joins. This makes a resin bound driveway one of the hardest wearing options for you to choose. Water will not sit in cracks and cause the material to fail and the entire driveway is porous so you won’t have issues with standing water. 

●    A resin bound driveway offers flexibility when it comes to the looks - especially when it comes to colour.
●    A resin bound driveway is compliant with planning permission rules on water drainage as it allows water to seep through.
●    A resin bound driveway will last upwards of 30 years and will stay looking great for all of that time.
●    You can have your resin bound driveway installed within two days - making it one of the fastest driveway options.

Your resin bound driveway mixture can be created using different grades of resin and usually with two main choices - epoxy or polyester. Each have their own positives and negatives

Choosing The Right Resin For Your Driveway

There are many reasons why your driveway contractor might choose one type of resin over another and often this comes down to what they are most comfortable working with and what they have found to be suitable. The contractor might ask the following questions:

●    Does the resin have excellent bonding properties and will it stick to both the aggregate and the surface it is being laid on? Can it do this while simultaneously allowing the surface to be permeable?
●    Is the resin strong enough to allow for cars driving over the surface without compressing? The surface needs to allow enough movement to prevent cracking and elastic enough to allow frozen water to expand within the structure of the driveway without causing cracking.
●    Is it strong enough to withstand general everyday use including walking or driving over the surface?
●    Is it resistant to chemicals, oil spills and dirt? You need your resin bound driveway to be easy to clean and for spills to easily washed away without needing to use chemical cleaners.
●    Can the resin withstand hot and cold temperatures? In the UK you can expect the temperature to drop as low as minus 10 and up to 40 degrees in the summer. The driveway needs to perform all year round without crumbling, melting or freezing. 
●    Is it UV resistant? Will the colour of the resin change over time and will this affect the look of the finished product and cause the homeowner problems?

The way that a polyester resin bonds to the aggregate allows water to continue to seep through the surface. This ensures it meets the drainage needs of your driveway, preventing puddles, frozen or slippery areas and patches of dirt

Does Polyester Resin Meet The Required Criteria For Driveways?

Polyester resin is a much more flexible product than epoxy resin and therefore it meets more of this criteria. Polyester is considered to be a higher quality product for the purposes of driveways where it is important that strength and longevity are balanced with flexibility and good looks.

●    A polyester resin will not fade or discolour in the sunlight - allowing you to choose lighter coloured stones and maintain the colours you want for your home.
●    A polyester resin is extremely strong, but also flexible. This is important when cars are driving over the surface on a daily basis
●    A polyester resin is easy to use and will bond to the stone and the sub base with ease. This will prevent the surface from chipping or lifting.
●    The way that a polyester resin bonds to the aggregate allows water to continue to seep through the surface. This ensures it meets the drainage needs of your driveway, preventing puddles, frozen or slippery areas and patches of dirt.

When comparing to an epoxy resin, the choice seems clear. Contractors who have been building resin bound driveways for some time will know that polyester offers better results and, therefore, is the option that they provide for their customers

What About Epoxy Resin?

A resin bound driveway is an excellent choice - but only if you know the right resin type to achieve the longevity you expect. There are two main options available to you when choosing a resin bound driveway: epoxy resin and polyester resin. But how do both types compare?

Epoxy resin is a more brittle option that can have problems with cracking over time. It is suitable in some situations and you may find contractors who will happily offer it. 

Epoxy is a good choice when it comes to repair work as it has excellent bonding properties and is very strong - but is allows less movement. You may find, however that your epoxy resin will yellow in UV light - causing the colour of your driveway to change over the years.

When comparing to an epoxy resin, the choice seems clear. Contractors who have been building resin bound driveways for some time will know that polyester offers better results and, therefore, is the option that they provide for their customers.
