• The sub-surface drains are then covered with a 150 mm thick layer of crusher run to assist
in the sub-surface drainage compacted to 95 % modifi ed AASHTO.
• Lay strip of 250 micron plastic down the edges of the excavation to prevent encroachment
of invader grass species.
The crusher run layer is covered with a 50 mm thick layer of coarse river sand.
• Add 100 mm thick layer of loam soil and mix in fertiliser as required by soil analysis.
• A grid of levelling pegs is to be set out by the specialist contractor at two metre intervals
with a longitudinal fall of 1:180 and a cross fall of 1:180. It is important to ensure that the
pegs do not pierce the geo-textile layer.
• Roll in 150 mm thick clay in layers. A 100mm coarse bully soil is to be spread, lightly
compacted and fi nished to an appropriate level. A 50 mm layer of fi ne bully soil is to be
spread and screeded to the fi nal level of the grid pegs, ensuring that the desired surface
fi nish and fall is attached.
• Wash grass sods to remove all soil and tease sprig apart.
• Prior to the commencement of grassing a true surface fi nish must be obtained, as detailed
above. Grass stolons (sprigs) of the species Cynodon dactylon (or latest approved grass
species) are to be planted over the entire wicket (all wickets of “the square”) at a square
spacing of 30mm apart. The planters must stand on wooden boards, or the like, whilst
planting the stolons to ensure minimum disruption to the surface fi nish occurs. The
stolons must be inserted to the layer of topsoil/compost mixture to ensure adequate root
development. Add a thin layer of sieved bully to a depth of not more than 15 mm (sieve
aperture of maximum 10 mm) over the grass and smooth.
• Apply fertiliser and water twice daily with a fi ne nozzle spray until grass shown signs of
sprouting.
• The contractor shall maintain in good order, the whole of the works, for a period of six
months after the certifi ed completion of grass planting.
• Continue to water until the grass has covered the pitch.
• Once the grass has established, cut to 15 mm and rub in sieved (1.25 mm gauge screen)
bully, to a smooth even surface, making sure that the grass tips protrude above the bully.
• Water daily, as required, until the grass shoots push through.

• Repeat the rubbing in process until a smooth even fi nish to the pitch has been achieved. The
fi nal level of the pitch should be slightly above the surrounding fi eld area.
• Commence with normal pitch preparation once all grass has grown through. The height
