DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
This invention relates to a method of erosion control and a turf product which is specifically adapted for use in the erosion control area.
2. Description of the Prior Art
It is often desirable to retain soil in areas where erosion is likely, say, in banks or cuttings or the like around roadwork so that the area can be stabilised and growth can be encouraged and subsequently act to bind the soil of the area against later damage.
Various approaches have been taken to do this. For example, the location of a netting fabric over the surface, placing other material, such as, say, wood chips over the surface and possibly retaining these with a netting or the like and direct planting of shrubs or the like onto the surface.
If it has been required to grass the surface, this has been done by placing turf thereover but, in general terms, this has not necessarily been completely successful.
SUMMARY OF THE INVENTION
The principal object is to provide a turf product which can be used in various applications but which is particularly useful in the erosion control area and also to provide a method of erosion control which basically uses this turf product.
In its broadest sense, the invention includes a turf product comprising matting of a fibrous material in association with a reinforcing mesh to give directional stability thereto, and turf located above the matting and mesh with its root system passing thereinto and adapted to pass therethrough and into an underlying surface.
This combination provides a product which has good stability and can readily be handled but which, once located, is readily retained in its located position.
The invention also includes a method of manufacturing a turf product which includes the provision of an impervious layer, locating a root matting on the layer in association with a reinforcing mesh or the like, and locating thereover turf, the roots of which can pass through the mesh and matting combination and can provide a stable and strong product.
It is preferred that the turf is located on the mesh and matting combination in the form of a washed turf having a strongly formed root system but it would be possible to grow turf thereon either from seed or stolons if this is required.
The invention also includes a method of erosion control comprising preparing the surface to be protected and laying on this surface a turf product as hereinbefore described, the arrangement being such that the product will tend to remain on the surface without moving, although it can be pegged or otherwise connected thereto or could be top dressed with sand or soil to ensure that there was no movement, the arrangement being such that the root system of the turf passes through the matting into the ground's surface to thereby consolidate the surface.
In order that the invention may be more readily understood, we shall describe the formation of the product, the product itself, and its use.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
Particular embodiments of the turf product will be described in terms of the accompanying drawings:
FIG. 1 is a schematic representation of a jute matting incorporating a reinforcing mesh.
FIG. 2 is a schematic representation of an embodiment of the turf product with turf growing through a reinforcing mesh and an underlying matting.
DETAILED DESCRIPTION OF THE DRAWING AND PREFERRED EMBODIMENTS
In a preferred form of the turf 60 product turf, preferably in the form of washed turf, is lain (FIG. 1) over jute matting 10 which incorporates as an integral part thereof a plastic reinforcing mesh 20 which is effectively sandwiched between the upper 11 and lower 12 sides of the jute matting.
Although in this preferred embodiment jute matting is used it may be of sisal or could even be of plastic or any other appropriate fibres. The form and thickness of the mat can also vary depending upon the required strength of the completed product as can the reinforcing mesh.
Thus the precise material of the matting is not germane to thi
