Sand-based with short synthetic grass – best for hockey.
40mm – 65mm long synthetic grass with shock-absorbent
rubber crumb and SBR infill. Best for football, more realistic
and safer surface than 2G
4G, 5G AND 6G PITCHES
Synthetic grass without need for rubber crumb. The existence
of 4G, 5G and 6G pitches is not recognised by any accredited
AC 6 / AC14 / AC20 ETC
Refers to the aggregate size of the macadam
(6mm / 14mm / 20mm etc)
Aliphatic binders are clear in color, UV resistant
and truly light stable, meaning that the color you
have installed is the color the surface will remain.
Aliphatic binders are more expensive than
ALL WEATHER SURFACE
A playing surface unaffected by rain but affected by frost and
Aromatic binders bond well to particles but tend
to “yellow” the material. After a few months this
“yellowing” will fade. Aromatic is honey colored
to begin with and will darken most colors
considerably as it is not truly UV resistant and
‘3G’ artificial grass with long pile and rubber particulate pile
filling is less suitable for hockey. Competitive (i.e. full contact)
rugby union and rugby league must be played on pitches
which have a high degree of shock absorbency as specified by
the NGBs of those sports.
To refill an excavated area with MOT Stone.
BASE (BINDER) COURSE
The lower surface beneath the wearing course,
usually providing the variance in CFH.
BS EN 1177 specifies a method for determining
the impact attenuation of playground surfacing.
To cut into the existing grass, concrete or
macadam in order to create a ridge which the
material can be ‘tucked’ into.
A strong building material made by mixing a cementing
material (such as Portland cement) and a mineral aggregate
(such as sand and gravel) with sufficient water to cause the
cement to set and bind the entire mass.
CRITICAL FALL HEIGHT
Represents the greatest height of head first fall, from which a
child, landing on a surface, could be expected to avoid
‘sustaining a critical’ head injury.
The time taken for the polymers within the
binder to toughen or harden. Once the binder has
fully cured, the surface is ready to walk on.
