Resin Bound or Bonded?

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 Terrabase Rustic 'minimum-dig' paving system) 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, Addabound, Terrabound, Terrabase) 

With resin bound surfacing  the aggregate is mixed with the resin into specific blends. The material is then trowelled down to a smooth finish similar to a screed (with no loose stones). Depths are specified depending on aggregate size and 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.

Resin Bonded (Addastone) - non porous paving

Resin bonded surfacing is a scatter system which provides texture and the appearance  of loose gravel. It is non porous.

A layer of resin applied to a suitable surface laid to falls and covered with loose aggregate. Once cured the remaining loose stones are removed. Thickness is governed by aggregate size. i.e. 1-3mm aggregate will have a nominal depth of 4mm. 

Resin Bound and Resin Bonded surfaces are suitable for a range of projects for both domestic and commercial use
