Abstract

A structure (10) defining an area for sporting activity. The structure (10) comprises an upper artificial surface layer (12), a shock absorbing layer (14) underlying the upper artificial surface layer (12), and a support structure layer (16) underlying the shock absorbing layer (14).

Claims (27)

1. A structure defining an area for sporting activity, wherein the structure comprises: an upper artificial surface layer; a shock absorbing layer underlying the upper artificial surface layer; and a support structure layer underlying the shock absorbing layer.
2. A structure according to claim 1 , wherein a membrane layer is provided between the upper artificial surface layer and the shock absorbing layer.
3. A structure according to claim 2, wherein the membrane layer comprises felt.
4. A structure according to any of claims 1 to 3, wherein a membrane layer is provided between the shock absorbing layer and the support layer.
5. A structure according to claim 4, wherein the membrane layer comprises a geotextile.
6. A structure according to any of the preceding claims, wherein the upper artificial surface layer comprises an infilled artificial turf system comprising a turf and an infill.
7. A structure according to claim 6, wherein the infill comprises a mixture of at least two different materials, wherein a first of the at least two different materials is an elastic material and a second of the at least two different materials is a non-elastic material.
8. A structure according to claim 7, wherein the first material comprises cork, and the second material comprises silica sand.
9. A structure according to claims 7 or 8, wherein the ratio of first material to second material in the infill is from 1 to 15 to 1 to 20 (dry weight).
10. A structure according to any of claims 6 to 9, wherein the turf is filled with infill to a height of 10 mm to 35 mm.
11. A structure according to any of claims 6 to 10, wherein the turf is filled with infill to a height of 25 to 30 mm.
12. A structure according to any of claims 6 to 11 , wherein the turf comprises a mixture of at least two different length fibres, and wherein the relatively shorter fibres have a wavy profile.
13. A structure according to any of the preceding claims, wherein the shock absorbing layer comprises a plurality of sub layers.
14. A structure according claim 13, wherein each of the sub layers comprises a plurality of shock absorbing units, wherein each of the plurality of shock absorbing units comprise a shock absorbing material, wherein the shock absorbing material is a foam.
15. A structure according claim 14, wherein drainage channels are provided between adjacent shock absorbing units.
16. A structure according to any of claims 13 to 15, wherein a sub layer with a greater thickness and a lesser density is provided between sub layers with a lesser thickness and greater density.
17. A structure according to any of the preceding claims, wherein the support structure layer comprises a frame, wherein the frame comprises a plurality of cavities.
18. A structure according claim 17, wherein the frame is formed of a plastics material.
19. A structure according claims 17 or 18, wherein the frame comprises cavities of different shapes and volumes.
20. A structure according claim 19, wherein at least a selection of the plurality of cavities are filled with a shock absorbing material.
21. A structure according claim 20, wherein the shock absorbing material comprises a foam.
22. A structure according any of claims 17 to 21 , wherein drainage channels are provided in the frame between adjacent cavities.
23. A structure according any of claims 1 to 16, wherein the support structure layer comprises a particulate material.
24. A structure according claim 23, wherein the particulate material comprises limestone.
25. A method of providing a structure defining an area for sporting activity, wherein the method comprises: providing a support structure layer as a lowermost layer; providing a shock absorbing layer overlying the support layer; and providing an upper artificial surface layer as an uppermost layer.
26. An infill for an artificial turf system, wherein the infill comprises a mixture of at least two different materials, wherein a first material comprises cork, and a second material comprises silica sand.
27. An infill according to claim 26, wherein the ratio of cork to silica sand in the infill is from 1 to 15 to 1 to 20 (dry weight).
