There are two different systems that use resin to fix gravel aggregates. These are Resin Bound porous paving (such as our BBA approved Addaset, Addabound and Terrabound range) and Resin Bonded paving (such as our Addastone range).
Resin Bound systems are porous and SuDS compliant when used with the appropriate base build up
Resin Bonded systems are non porous.
Resin Bound porous paving (e.g. Addaset)
In resin bound surfacing the aggregate is mixed with the resin. The material is then trowelled down to a smooth finish similar to a screed (with no loose stones). Depths are specified depending on use, normally 12mm, 16mm, 18mm or 24mm.
SUDS (Sustainable Urban Drainage Systems)
Addaset is porous, allowing water to permeate/percolate through the surface and beyond when a suitable base build-up configured for SUDS (Sustainable Urban Drainage Systems) has been installed.
