Playing surface structure and method of construction of a playing surface

1. A playing surface structure comprising:

a surface carpet layer;

a resin impregnated textile layer;

at least one random pile layer comprising a compact resin loaded fibre stratum;

at least one layer of stratified fibrous material;

wherein the surface carpet layer overlays the textile layer, the textile layer overlays such random pile layer, and the layer of stratified fibrous material is overlain by the at least one random pile layer;

wherein the layer of stratified fibrous material is a lapped fibre layer and wherein the lapped fibre layer is lapped vertically.

2. A structure according to claim 1 wherein the random pile layer is a layer having fibres that extend generally in vertical and in horizontal directions, and in angular directions inclined both vertical and horizontal.

3. A structure according to claim 1 wherein pile of the or at least one random pile layer is laden with particulate material.

4. A structure according to claim 1 wherein the random pile layer is at least partially covered with a layer of particulate material.

5. A structure according to claim 4 , wherein at least a portion of the particulate material in the layer covering the random pile layer is rubber and is bonded to the resin impregnated textile layer.

6. A structure according to claim 1 wherein the carpet layer includes a pile which is laden with particulate material.

7. A structure according to claim 1 wherein the pile of the random pile layer is laden with particulate material which comprises one of sand, rubber particles, or sand and rubber particles.

8. A structure according to claim 3 wherein the particulate material is brushed into the random pile layer.

9. A playing surface structure comprising:

a surface carpet layer;

a resin impregnated textile layer;

at least one random pile layer comprising a compact resin loaded fibre stratum;

at least one layer of stratified fibrous material;

wherein the surface carpet layer overlays the textile layer, the textile layer overlays such random pile layer, and the layer of stratified fibrous material is overlain by the at least one random pile layer;

a plurality of alternating random pile layers and layers of stratified fibrous material.

10. A playing surface structure comprising:

a surface carpet layer;

a resin impregnated textile layer;

at least one random pile layer comprising a compact resin loaded fibre stratum;

at least one layer of stratified fibrous material;

wherein the surface carpet layer overlays the textile layer, the textile layer overlays such random pile layer, and the layer of stratified fibrous material is overlain by the at least one random pile layer;

wherein the layer of stratified fibrous material overlays a further random pile layer.

11. A playing surface structure according to claim 1 comprising, in order:

a surface carpet layer having a sand laden pile;

a resin impregnated textile layer optionally having rubber particles bonded thereto;

a first random pile textile mat which is laden with rubber particles, and which comprises a compact resin bonded fibrous stratum;

a vertically lapped textile mat; and

a second random pile textile mat which is laden with rubber particles, and has a compact resin bonded fibrous stratum.

12. A playing surface structure according to claim 11 wherein a second vertically lapped textile mat lies beneath the second random pile textile mat.

13. A playing surfave structure comprising, in order:

a surface carpet layer having a sand laden pile;

a resin impregnated textile layer having rubber particles bonded thereto;

a first random pile textile mat which is laden with rubber particles, and which comprises a compact resin bonded a fibrous stratum;

a verically lapped textile mat; and

a second random pile textile mat which is laden with rubber particles, and has a compact resin bonded fibrous stratum.
