What bases can be used for Resin Bound Systems?

Resin bound systems require a stable sub base to which the resin bound system can be applied. A typical base for a resin bound driveway or other surface, whether new or existing, can include the following:

  •       Tarmac
  •       Asphalt
  •       Concrete

Always make sure any base has been thoroughly cleaned and prepared accordingly. You can find more information about preparing a base for a resin bound system in our comprehensive Knowledge Centre

For help with preparing your surface, view our guide.

Is your surface suitable for purpose? 

The base should be suitable for the load it expected to carry once the resin system is applied. There is no preferred base as this can vary depending on the system used and advice from your resin bound supplier should be sought prior to application.

For example, the ideal base for a resin bound driveway will depend on how many vehicles are likely to be using it regularly, and how heavy these are.

Surfaces that have fewer joints and are predominately large slab areas, such as tarmac or concrete, provide the best finish. 

Remember, to ensure your resin bound system is SUDs compliant, please ensure it is placed on a suitable permeable base. 

Bases to avoid 

Bases made up of paving type products such as block paving, sets or flags are not suitable for a resin bound system. The number of cracks or lines below the surface would ultimately lead to cracks in the resin and failure of the system due to the extreme pressure loaded onto the surface day to day.  

Is a granular sub-base suitable?

No, resin-based surfacing cannot usually be laid on a granular sub-base (such as a layer of MOT Type 1, gravel or sand) no matter how well compacted. The only exception to this is applications such as tree pits. 

Damp striking up through the base could affect the resin and, if there is a high moisture content in the base, it can seep into the resin with adverse effects such as clouding of the resin.

Newly laid surfaces 

Any new surface should be allowed to cure properly prior to the application of resin bound systems. In the case of bitumen surfaces a minimum of 7 days should be given to allow it to weather and oxidize.

For concrete, at least 28 days should be given to allow it to cure properly. With any base, it is important that the moisture levels on the surface meet an acceptable level as recommended by the resin manufacturer. 

In all cases, the manufacturer's advice and recommendations should be followed regarding preparation, pre-cleaning or all other requirements.
