When discussing types of subbase for laying resin bound or bonded paving, it’s important to note that the quality of the original surface plays a vital part. Like anything that is constructed, start with a solid, high-quality foundation so that from the start, you are minimising the chances of future problems/failures happening. Having said that due to the flexible nature of existing surfaces, they don’t need to be completely perfect prior to installation.

Here are some of the most common types of sub-surfaces for laying resin bound and bonded paving:

#1. Concrete

This is a popular choice for developers and consumers alike as it provides a cost-effective, stable, and solid base to begin with. Concrete is regularly used as a foundation for this kind of surfacing as it is ideal for heavy foot traffic and can withstand the weight of vehicles.

In terms of resin bonded installations, we would potentially scratch coat this type of surface if the texture is more open before installing our product onto it, and always with the addition of a concrete primer to aid adhesion. This extra time taken provides additional strength & flexibility that helps achieve a level, durable finish.

#2. Asphalt or Tarmac

these surfacing types are durable and long-lasting, used regularly due to it being cost-effective and being able to withstand heavy traffic. If the surfacing is newly constructed, we find it is best to wait until the material has completely cured, and ideally left a minimum of 7-10 days, if possible, to allow for oxidisation and settlement to avoid cracking and debonding.

In relation to specification, resin bonded should ideally be laid to a close-graded wearing course (top layer) surface to allow the resin to sit on top without dropping through, meaning aggregate can bond sufficiently. This system provides a waterproof, non-porous finish which can in turn protect the sub-base from weathering and wear.

Comparably, resin bound should ideally be laid to an open textured binder course layer, allowing moisture to permeate through the surfacing on account of its permeability and SUDS compliance.

To conclude, the versatility of these surfacing options comes at a big advantage, its ability to be laid on porous and non-porous surfaces alike allows us to satisfy the needs of our clients. From driveways to patios, walkways to gardens, resin bound and bonded paving is a cost-effective and low-maintenance solution that can exceed your expectations.
