Resin bound surfaces are an effective surfacing option offering many benefits. Long lasting, low maintenance, with limitless colours and designs to choose from, it’s an increasingly choice for both domestic and commercial surfacing projects.
The lifespan of a resin bound surface depends heavily on what sits beneath it. An unsuitable base can lead to serious problems, like cracking, moisture becoming trapped, and premature wear.
So, with that, which bases are best for long lasting resin bound surfaces? Let’s explore your options.
Base Options for Resin Bound Surfaces
For resin bound surfaces, there are a few base options to consider:
- Concrete
- Tarmac
- Grid systems
Each has its pros and cons, but when constructed correctly, all can serve as a suitable base. The best choice will depend on your site conditions, budget, and drainage requirements.
Comparing Base Options: Pros & Cons
Concrete
New or old concrete can be a suitable base for resin bound surfacing. If laying on old concrete, ensure it’s in good condition first. Any damage should be repaired beforehand.
If laying new concrete, remember the concrete base needs time to fully cure. Depending on factors like weather, you should wait at least 14 days before having your resin laid. It will also need to be primed with a polymer primer.
Permeable concrete is best, as non-permeable can absorb moisture which could affect the lifespan of your driveway. With non-permeable concrete, you’ll also need to have falls and drainage installed, which is not only an extra expense, but also means the project will take longer to complete.
Tarmac
If you’ve got a tarmac or asphalt surface is in good condition, it makes an ideal base for your resin bound surface. Similarly to concrete, if your tarmac base is not permeable, you will need to have drainage installed.
If you’re looking to install a new tarmac base, permeable is the most efficient choice. A new non-permeable driveway will need planning permission. It will also need drainage.
A top advantage of having a tarmac base is that the resin can be directly installed on the tarmac, as it creates chemical and physical bonds. The final resin layer is only 15–25mm (depending on stone size), so no drilling into the tarmac is required.
Grid Systems
Grid systems are environmentally friendly and free draining. While this base isn’t quite as strong as concrete or tarmac, you will still have a sturdy base for your resin bound surface.
Unlike concrete and tarmac, grid systems don’t need curing time, so can really sped up the construction process. All in all, they’re a practical alternative.
The Best Base For Resin Bound Surfacing
The best base for resin bound surfacing depends, particularly on how the surfaced will be used. Consulting with your chosen contractor, they should help you make the right choice based on your needs. If used frequently, especially by heavy vehicles, permeable concrete or tarmac is highly recommended.
If you already have a solid concrete or tarmac base in place, you’re good to go provided it’s in good condition. Any damage should be repaired first to ensure the best results. Crushed aggregate, however, isn’t suitable, and a proper base such as those we’ve suggested should be used instead.
