Resin Bound Gravel Specification: The Essential Guide

resin bound gravel specification

Creating a driveway that will impress the neighbours used to mean intricate paving that would take days to install, and cost a fortune. In the last few years, new methods have been developed, with resin bound stone driveways a firm favourite with homeowners.

Not only do resin bound driveways look great, but they are long lasting, durable and they can be laid in a matter of hours (assuming your current driveway is a good base).

As the name suggests, resin bound stone driveways take resin, and combine it with stone or gravel to create a thick mix that is simply trowelled onto a prepared base. The mix is laid to a depth of at least 15mm and the result is a hard-wearing and beautiful driveway.

The thing that sets this type of driveway apart from the rest is the fact you can choose the colour stone you would like added.

This means that the colour choice is only limited by the available stones; everything from cream or white through to deep dark black can be achieved. Even mixed stones can be used to create an interesting effect.

The sub base is also an important consideration, and how this is constructed is probably more important than the driveway itself. This is why resin bound contractors work to the very particular specifications that meet the guidelines set out by councils, environmental groups and themselves.

The importance of creating paths and driveways that do not damage the environment cannot be underestimated and this is why these driveway options are so popular.

Resin bound installers will all have a set of specifications that they need to stick to to comply with SuDs. In some cases, these are set out by councils or local authorities, to ensure that driveways and other paths and patios do not have a detrimental effect on local wildlife and water tables

Resin Driveways: SuDS Specifications

Your driveway should adhere to Sustainable Drainage Systems (SuDS), and the specification of the stones and base can influence how well your driveway will respond to water.

One of the benefits of resin bound driveways over other options is the way that it is free draining. You will not have water run off or pools of water on the surface. The water will simply pass through the material and into the ground below – this is important for the environment.

SuDs work to ensure that water flows in a natural way and nourishes the ground in the normal way – even when the front garden is used as a driveway. By making sure that your driveway complies with SuDs you are:

● Reducing the impact of flooding on your local area
● Protecting water quality by preventing polluted water reaching drainage systems
● Providing a habitat for wildlife under your driveway and in the immediate area
● Allowing the free growth of vegetation, and therefore protecting the stability of the ground

Resin bound installers will all have a set of specifications that they need to stick to to comply with SuDs. In some cases, these are set out by councils or local authorities, to ensure that driveways and other paths and patios do not have a detrimental effect on local wildlife and water tables.

In other cases, it will be a specification that they have drawn up for their own requirements, because their experience has told them what works. They can then set these specifications for their workers – ensuring all projects adhere in the same way.

As you can see, the detail can be very specific, and contractors must adhere to these details in order to ensure a product that will work well for the customer, and a driveway or path that meets the gravel specifications for resin bound surfaces

Resin Driveways: Gravel And Sub-Base Specifications

For driveways or paths the specifications are going to vary but they generally follow a basic pattern to fit in with SuDS. For example it may specify that an aggregate of 2-5mm will require 18mm depth, while aggregate of 1-3mm will need a depth of 12mm.

Below this, there could be an asphalt layer of a minimum of 70mm and below that 175mm of a granular sub-base such as crushed concrete or recycled aggregates of less than 20mm.

Below all of this a permeable membrane over the existing ground to prevent soil migrating upwards, while still allowing water to seep into the ground.

As you can see, the detail can be very specific, and contractors must adhere to these details in order to ensure a product that will work well for the customer, and a driveway or path that meets the gravel specifications for resin bound surfaces.

Resin Driveway Specifications: Choosing Your Gravel

There are around 50 different resin bound gravel combinations that you could choose, so knowing which will be best for your needs is down to both your choice, and the need of the contractor to meet the SuDS compliance specifications.

But you can bear the following in mind when deciding on the gravel you will want:

● The gravel used will usually be granite, flint or quartz, but it must be treated before it can be used. In particular, it will need to be separated into sizes, washed, and thoroughly dried in a kiln. Gravel that is not cleaned will not bond properly to the resin. Any that is not fully dry will risk leaving white patches on the driveway or path as the water leaches out.
● When it comes to colour, it is possible to choose any combination you want from lighter natural looking stones, to unique colour combinations that will make your home really stand out. It is important to ensure that you know the ratios of each colour, so that you can recreate the mix if you need more stone in the future.
● The size of the gravel ranges from 0.1mm to 10mm, however, most driveways will require stones of between 3 and 8mm. Borders may use the larger stones, and the smaller ones can be used to fill smaller gaps. The larger the stones, the more likely the driveway is to be rough in texture. Smaller stones will leave a smoother finish.

Resin bound surfaces offer something different and something that meets the environmental concerns of both homeowners and the local authority-and look stunningly stylish as well!

Resin Bound Material: The Superior Surfacing Solution

The porous nature of resin bound surfaces makes it ideal for all kinds of applications, but in particular driveways, paths and patios. It is also favoured by councils for roadways because it does not allow standing water when prepared to the correct specifications of the area in which is laid.

Different preparations can be more of less porous, allowing them to be used in different ways. For example, the base of a tree will need to be more porous than a flat pathway.

Resin bound surfaces offer something different and something that meets the environmental concerns of both homeowners and the local authority.

With so many homes having their front gardens paved over, having a permeable surface that allows free drainage means there is a minimum of loss of habitat and flood risk. These days, with climate change, that is even more important than ever.
