What is the best base for Resin Bound aggregate?

By December 23, 2023January 11th, 2024No Comments

Resin bound systems, as with any other surface, require a stable sub-base. However, resin bound surfaces when applied, need a strong base to adhere to. A typical base for a resin bound driveways, walkways, parking lots or other surfaces, depends on whether you wish to have a permeable, or impermeable surface. If you’re lookng for an impermeable surface, then resin bound aggregate system is best applied on

  • Concrete

Always make sure the base that is receiving the resin bound aggregate layer is thoroughly cleaned and prepared as per manufacturers specifications. You can learn more about preparing a base for a permeable resin bound system in an upcoming Knowledge Centre.

Is your surface suitable for your purpose?

The base are 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. 

Please ensure that your resin bound system is placed on a suitable permeable base to ensure SUDs compliance.

Bases to avoid 

Paving type products such as block paving, sets or flags do not suit 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 

You should allow any new surface to cure properly prior to applying resin bound systems. In the case of bitumen surfaces, allow it to weather and oxidize for a minimum of 7 days.

For concrete, at least 28 days will taken 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 recommendations are follow regarding preparation, pre-cleaning or all other requirements.
