Resin bound vs resin bonded surfacing
So what is resin bound surfacing and resin bonded surfacing? Crucially, we explore the differences and find out why resin aggregate mix is used for Drives, Patios and Pathways. First off, Resin bound and resin bonded are two different methods used in creating decorative and functional surfaces. However, both use resin and aggregates and involve using resin as a binder. Although, they differ in terms of the application process and the final appearance.
What is Resin Bound Surfacing?
Resin bound is a surfacing technique where a mixture of resin and aggregates is thoroughly mixed together and then applied to a prepared surface. Incidentally, aggregate can include gravel, stone, or recycled materials. And it's the stone which can be coloured to match the desired design, as there's over 40 colour options.
The mixture is evenly spread out to create a smooth, seamless, and durable surface. The resin fully coats and binds the aggregates together, giving the appearance of a solid surface. This method is known for its permeability. Therefore, it's SuDs compliant, allowing water to pass through the surface and into the ground which can help with drainage and reduce surface water runoff. Advantages of resin bound surfaces include:
- Aesthetically pleasing, with a smooth and decorative finish.
- Permeability, allowing for efficient drainage.
- Low maintenance requirements.
- Suited for pedestrian and vehicular traffic.
What is Resin Bonded Surfacing?
Resin bonded, on the other hand, involves applying a layer of resin to an existing surface such as concrete or tarmac and then scattering loose aggregates onto the wet resin. The aggregates adhere to the resin but the majority remain exposed, creating a textured and decorative finish. Crucially, unlike resin bound surfaces, resin bonded surfaces are not permeable because the aggregates are not fully encapsulated by the resin layer. Advantages of resin bonded surfaces include:
- Textured appearance with a variety of aggregate choices.
- Suitable for enhancing the appearance of existing surfaces.
- Provides good skid resistance.
- Generally quicker to install than resin bound surfaces.
In summary, the main difference between resin bound and resin bonded surfaces lies in how the aggregates are integrated with the resin. Firstly, resin bound surfaces create a uniform, solid appearance that are SuDs compliant, unlike resin bonded surfaces. Secondly, resin bonded showcase exposed aggregates on top of a resin-coated base. The choice between the two methods depends on factors such as the desired appearance, functional requirements, budget, and the existing surface conditions.
