Specification - Topography
The topography refers to the natural and artificial features of the application area and should always be given consideration prior to installing a resin bound surface. Does the installation area have restricted access, slopes, steps, leaf-fall, drain covers or uncommon traffic?
● Restricted Access
Does the installation area have restricted access? Working in enclosed areas (such as between a garage and garden wall) can prove tricky. It should be decided where the installation would begin and end and which areas of access will be affected. A mixing area should also be chosen ensuring there is adequate space for delivery of aggregate/resin pallets and protection for members of the public.
● Slopes
Any incline greater than 10% (5.71⁰) must feature a Silex anti-slip finish to the resin bound surface and the incorporation of a stabilisation grid should be given consideration for any inclines greater than 20% (11.3⁰). A resin bound surface is not ideal for inclines exceeding 30% (16.7⁰) and we recommend that consideration is given to the use of StarScape PRO resin bonded surfacing as this benefits from high friction surfacing properties.
● Steps
If the area has steps which are to feature a resin bound surface then a non-slip nosing profile should be used.
● Leaf-fall
If the area is surrounded by deciduous trees or shrubs then it should be noted that the resin surface may require a Silex anti-slip finish and protection from leaf-fall until fully cured.
● Drains and Manholes
If the application area has pre-existing drains or manholes then these may need to be replaced with high strength polymer concrete drainage channels and suitable recessed cover, manholes.
● Uncommon traffic
Whilst the completed area may appear to be used by a single, non-turning car any specification should be created around a ‘worst case scenario’. Is the area used by larger vehicles for turning? Do refuse collection vehicles access the area? Does a window cleaner park or turn a van around?
