STAYturf
Originally, the most common engineered solution to concentrated water flow was to line channels with rock or concrete and dump the stormwater into the nearest creek. However, this method also allows for the transportation of foreign matter downstream, which in turn leads to serious pollution.
For many years turf farmers have been promoting their product as a viable alternative to some revegetation techniques. However, they have been viewed as either too expensive or as not having the strength to accommodate the high sheer stresses of fast flowing water. The Managing Director of Jimboomba Turf Group recognised the need for a mature turf product which could somehow be strengthened to enable it to withstand high erosion forces.
STAYturf is a verified product that can replace rock or concrete in many places in addition to significantly reducing the amount of downstream pollution. It is a mature turf product that has been produced by establishing soil free turf on an organic geotextile reinforced with UV stabilised Turf Reinforcement Mesh. Couple this with the aesthetic and safety benefits of natural grass and you are provided with the ultimate solution to channel protection.
STAYturf testing was independently designed and supervised by the School of Environmental Sciences at the Griffith University. The product was installed into a fleshly excavated channel on an 18% gradient and immediately subjected to a flow rate of 450 litres per second. At a velocity of 3.3mps, there was no soil loss from the STAYturf lined channel. Copies of the Griffith performance report are available for your review.
STAYturf has been successfully installed in several areas, including overland flow paths, batter drains, catch drains, creek banks, and roadside drains as a cost effective alternative to previous methods such as rocks and concrete.

Installation:
Site assessment and appropriate anchoring techniques provide immediate resistance to high water flow. Once established, the interim anchoring is no longer required.
Solution:
STAYturf provides effective resistance to water volume and velocity, facilitating an engineered solution to erosion problems.
Application:
STAYturf has been successfully used in overland flow paths, channels, batter chutes, abutting culvert aprons, embankments and batters and is a cost effective and viable alternative to hard armour protection such as rock or concrete. STAYturf has the added advantage of improving downstream water quality with its sediment filtering ability. STAYturf has also been used to compliment rock mattress protection work.
Clients:
In addition to our documented case studies, STAYturf has been used extensively throughout South East Queensland by civil contractors and local councils, with licensees in New South Wales, Victoria, Mackay, Cairns, and two in the USA.
STAYturf has found a recognised place in the market and is now being specified by many councils, civil engineers and landscape architects.
