3G PITCH
3G PITCH
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
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 governing body.

ALIPHATIC BINDER
ALIPHATIC BINDER
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 aromatic binders.

ALL WEATHER SURFACE
ALL WEATHER SURFACE
A playing surface unaffected by rain but affected by frost and snow.

AROMATIC BINDER
AROMATIC BINDER
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 light stable.

ARTIFICIAL GRASS
ARTIFICIAL GRASS
‘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.

CHASE CUTTING
CHASE CUTTING
To cut into the existing grass, concrete or macadam in order to create a ridge which the material can be ‘tucked’ into.

CONCRETE
CONCRETE
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
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.

CURE TIME
CURE TIME
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.
