Resin Bound Vs Resin Bonded
A very frequently asked question we receive is, “what is the difference between resin bound and resin bonded?”. Although they sound very similar they are totally different products with different attributes but distinguishing the two without seeing them can often be quite difficult.
Let’s start by outlining the basic differences.
Resin Bound
Resin Bound paving has been around since the late 1990s. It has, however, become more and more popular over the last 8-10 years with its benefits becoming more widely understood. It is essentially a mix of polyurethane resin with crushed dried aggregate. The resin and the aggregate is mixed in a forced action mixer. This process binds the aggregate together. The fully coated aggregate is then screeded evenly over the surface of a suitable base and troweled to a smooth finish. With resin bound, you can expect a solid, permeable surface with great aesthetics and durability. Resin bound is usually applied to the surface at a depth of between 18mm-20mm.
Resin Bonded
Resin Bonded is the process of coating a flat surface with polyurethane resin and scattering a layer of crushed aggregate on top. This was once a very popular choice for decorative surfacing, especially for larger areas, as there is only a fraction of resin used per metre compared to resin bound. It carries some positive attributes such as; ease of application, speed of application and versatility. This being said, resin bonded has come under some scrutiny in recent years due to its lack of longevity among other things.
