Fundamental Things You Need to Know Before Using a Permeable Resin Bound Paving


Statistics strongly suggests that houses in England are more likely to get flooded than robbed. That’s because flash flood is among the most significant problems in the UK. The annual cost of flooding in England alone amounts to more than £1 billion each year. If your house is prone to flooding, you should consider using construction materials such as resin bound paving to prevent flood water from accumulating in your residential or commercial property.

Which is better: Bound or Bonded?

There are two types of gravel aggregate system with resin. One is referred to as resin bound, while the other is resin bonded. A lot of people tend to think that they’re the same materials, but in truth, they’re not.

In a resin bound system, the gravel aggregates are completely covered in resin. A special process is used to ensure that the polyurethane resin and gravel mix are combined. The mixture is then carefully poured and manually trowelled to create a smooth and colour-constant surface.

In the resin bonded system, contractors don’t need to create an aggregate-resin mixture. Instead, they sprinkle the aggregates onto the resinous solution. This type of resin aggregate layer is rougher compared to the bounded type. Bonded resin paving is also less durable than bound pavement.

Between the two type of resin paving system, it’s better to choose the resin bound permeable paving because apart from its durable nature, it is also highly porous. It will allow flood water to permeate into the groundwater system. There are minute voids within the layer of aggregates and resin which allow water to pass through easily.

Disadvantages of using resin bound paving

There are a few disadvantages of using resin bound paving. First of all, you will need to dedicate time to maintain the paving. The little cracks tend to harbour spores and seeds. During the rainy season, a resin bound pavement easily gets filled with moss and weeds. You will need to have it regularly cleaned to minimise organic overgrowth.

Another disadvantage is that it tends to crack easily if the resin and aggregate mix is not applied correctly. This is why it is absolutely important to hire a professional contractor to get the best results. A good contractor knows the right consistency of the mixture. Moreover, they also know how thick a good layer should be.

As much as possible, avoid using a resin bound paving for heavy traffic areas. Frequent reversing and turning of your cars on the resin paving may cause some of the layers to lift. You should consider using another type of paving to avoid inconvenience.

Knowing when to use a resin bound permeable paving is crucial to every commercial and residential project. It can significantly minimise flooding in your property. It also looks nice and classy. To fully maximise the permeability of the material, you need to ensure that it is applied properly. It also requires to have a permeable surface underneath.
