Installation & Maintenance
Site Preparation
The surface must be cleaned of rocks and vegetation. Erosion and gullies should be filled. As loose soil will subside with moisture the area must be compacted to a minimum of 85%. The soil should be treated to create suitable grass growing conditions. i.e. pH and nutrient levels.
Installation
STAYturf is a flexible product which will follow the contours of the natural ground, and it is recommended that STAYturf is rolled out in the direction of the water flow.
An anchor trench of 200mm x 200mm should be installed at the leading edge. STAYturf is installed into the trench and pinned with 150mm steel staples at 500mm spacings. The trench is then backfilled and compacted. Wooden pegs ( 25mm x25mm ) are then inserted at 500mm centres.
STAYturf should be pulled taut to prevent sagging or ripping before pinning down. 100% of the root material on the back of the STAYturf must be in contact with the soil.
Joins
All joins must be overlapped.
For lineal joins (i.e. Side joins where the installation is more than one roll wide) , the overlap should be 150mm. Wooden pegs (25mm x 25mm) should be installed along the sides (including the overlap) at 2.5m spacings.
Lateral joins should be overlapped by 200mm and pegged with 25mm x 25mm wooden pegs at 500mm spacings. Anchor trenches should be installed every 30m to 40m.
For extreme flow rates, anchor trenches should be installed at the start of every roll.
Watering
STAYturf must be watered within 60 minutes of installation. For installations which run over some hours, provision should be made for water to be available. Care should be taken to ensure that water does not run off the STAYturf on to unprotected soil. STAYturf should be watered for at least 4 weeks after installation.
Fertilising
STAYturf should be fertilised on the day of installation at the rate of 250g per square metre. The fertiliser should have an NPK of 14:4:11 or similar. We recommend a slow release fertiliser be used.
Mowing
If required mowing can commence as soon as the STAYturf is well rooted and the pegs have been removed. We recommend a minimum mowing height of 35mm. Care should be taken in V-drains not to run tractor wheels in the bottom of the invert when it is wet as this may damage the product.
STAYturf in bushland areas does not require mowing.
Summary
Once established, STAYturf will survive under most conditions. Where aesthetics demand improved visual presentation, normal grass management practices should be adopted. Wooden pegs must be removed once STAYturf is established.
