Frequently Asked Questions
Can I drive on it?
Yes, SUDwell™ Resin Bound Permeable Paving can be designed for every application and can be installed to take heavy traffic such as buses and lorries.
Is the resin toxic?
No. Once installed SUDwell™ Resin Bound Permeable Paving is an inert material. Part of the resin blend is derived from natural plant extract.
How is it permeable?
Dependant on what stone choice is chosen for the individual project, generally the stone size will be a mix of between 3-6mm. Once cleaned and dried, the stone is then bound with SUDwell™ Resin Bound Permeable Paving resin, and once cured the stone size gives optimised strength but allows water to permeate through the voids of the stone bonded together.
What depth is it normally laid at?
The depth of SUDwell™ Resin Bound Permeable Paving will vary for each project, this depends on the type of application and the size of the aggregate used. Typically the depth of SUDwell™ is approximately 15-20mm laid onto a prepared and solid sub-base ie open lay asphalt or concrete for vehicular use and between 6-9mm for pedestrian use
Can I lay it myself?
DIY Kits are available for smaller areas. For projects larger than 10m² it is recommended you use a SUDwell™ Resin Bound Permeable Paving fully trained installation team. We only recommend an area of this size or smaller because the resin cures so quickly. Unless you are well prepared and get the stone laid quickly, it can set and becomes impossible to smooth and get the desired result.
How long will it last?
SUDwell™ Resin Bound Permeable Paving comes with a 10 year guarantee, however the resin technology suggests it will last in excess of 25 years.
How long does it take to cure?
SUDwell™ Resin Bound Permeable Paving will be suitable for use after 4-6 hours for pedestrian traffic applications, and 12-16 hours for vehicular traffic. For heavy use, 24 hours would be ideal where possible to ensure a fully cured surface. These times can be doubled in colder laying temperatures ie winter.
Is it easy to clean?
Yes. SUDwell™ Resin Bound Permeable Paving is very low maintenance and easy to look after. It can be cleaned with a power wash or simply a stiff broom to sweep away any leaves. SUDwell™ recommends sweeping leaves to prevent vegetation growth or staining. If staining or growth appears and if a driveway is north facing, we recommend cleaning with diluted bleach to bring these areas back to brand new.
For general cleaning we recommend using a light detergent such as washing up liquid to bring the stone back to brand new.
Can I use the resin with aggregate I already have?
In principle yes; although any aggregate would need to satisfy our minimum quality standard and be clean and dry. All of our stone comes prepared and goes through a rigorous screening, cleaning, and drying process. If this is something you would like to discuss further, please contact us for more information.
