• Once the grass is established, top dress. Cover grass with thin layer of sieved of top soil to
a depth of not more than 8 mm over the grass and smooth.
• Water daily or as may be required.
• Regular soil tests should be taken to ensure that the correct fertilisation program is carried
out.
• Grass matting should be avoided and always controlled by vertical cutting. Length of grass
should never be longer than 8 mm when played on.

terms with a Civil Engineers specifi cations. The general specifi cation may, however, be described as

levels with a maximum gradient of 1:10 and particular emphasis on natural sub-soil
drainage.
• Rip and compact in-situ earth to 95 % modifi ed AASHTO.
• Install sub-surface drainage comprising 110 mm diameter agricultural drains placed in 450
x 600 mm deep drainage system to the perimeter of each tennis court.
• Sub-surface drains to be lined with a “Bidum” Hessian layer and fi lled in with 19 mm
crusher run stone. Sub-Surface drains to connect at the lowest point to a storm water catch
pit which should be connected to a storm water main.
• Insert sub-surface irrigation system to specifi c manufacturer’s instructions.
• The compacted earth layer must be covered with a 125 mm thick layer of crusher run to
