Resin Bound Surfacing: Things to Consider Before Installation

UV STABILITY
The significance of UV Stability is frequently overlooked in Resin Bound surfacing. You can find two types of Resin Bound resin on the market; UV Stable resin, and Non-UV stable resin also referred to as MDI. At Resin Bonded Ltd our BoundWorx resin is UV Stable.If you don't use a UV Stable resin in that case your surface will turn a deep yellow-brown colour. Patches will also appear where items like plant pots have been overlooked and in shaded areas. Don't let the contractor convince you otherwise, the discolouration WILL be obvious within a matter of weeks even though you choose a dark coloured stone.
ANTI SLIP
Ask your contractor to include either a clear sand or glass grit within the Resin Bound surfacing. Usually do not worry, the inclusion of sand or glass within the mix will not affect the colour of the overall finish. Should they lay a variety of straight aggregate and resin, minus the aid of anti-slip sand or glass grit, then your surface will be extremely slippy when wet. For areas that want extra traction you can sprinkle an excellent glass grit in to the surface after installation while the resin is curing. This should not, however, substitute the use of anti-slip products in the mix itself because the top layer of glass grit will wear away as time passes.

GUARANTEE
You should always get yourself a written guarantee from any contractor doing works for you personally. Contractors using top quality products and correct installation options for Resin Bound surfacing could have no problem providing you with this.
In the event that you?re unsure concerning the reputability of a tradesman there are various websites such as trustatrader and checkatrade that vet and monitor top quality contractors. Failing that, we have a network of contractors nationwide who we've trained and monitored ourselves.

STRONG BASE
That is especially important when you are overlaying a preexisting surface. The base beneath the resin MUST be solid without structural movement, and strong enough to take the anticipated loading. Any sinking or cracking in the bottom will be reflected in the Resin Bound surfacing. In the event that you?re unsure about the stability of one's existing surface, consult your contractor or an engineer.

The base must also have appropriate drainage so that the water has somewhere to go beneath the resin layer. We recommend Open Graded Tarmac as the ideal permeable base, or concrete laid to falls with suitable drainage channels. We'd not advocate laying Resin Bound surfacing straight over compacted MOT as it will not provide enough stability.

LAYING CONDITIONS
Ok, and that means you?ve checked the UV stability and anti-slip properties of the materials, and you?ve ensured that the contractor offers a guarantee and is laying over a solid base. The final thing you have to be aware of may be the weather. The materials Should be installed on a dry day, if any rain or moisture enters the resin before it has cured you then will begin to see white patches blooming and the machine will fail. If it rains the night time before installation is due to happen, the contractor should make sure the bottom has been dried off with a blow torch.
This is also a reason why Resin Bound surfacing cannot be done using existing aggregates; any moisture or contamination from the existing stones will enter the resin and lead it to fail. Each of the aggregates that we supply to go with our resins have already been professionally washed and kiln dried.
