• The sub-surface drainage system is to be connected to a storm water system to ensure<br />
proper drainage.<br />
• A 250 micron damp proof layer is to be installed below a 125 mm thick (20 Mega Pascal<br />
design strength) concrete surface bed fi nished smooth to ensure proper adhesion.<br />
• Sealers <strong>and</strong> curing agents should not be used since these may affect the adhesion of the<br />
artifi cial grass surface.<br />
• All concrete surfaces need to be dry <strong>and</strong> dust free prior to the placement of the fi eld<br />
surface.<br />
• A 25 mm thick cement levelling screed needs to be placed to true <strong>and</strong> smooth levels.<br />
• Any level defects are to be fi lled in to ensure a smooth <strong>and</strong> even fi nish. Any projections will<br />
damage the artifi cial fi eld surface when subjected to use.<br />
• A number of manufacturers’ artifi cial synthetic surfaces are available. The surfaces have<br />
to be applied strictly in accordance with the manufacturers’ instructions. (See Drawing<br />
