- each tubular pocket 12 is obtained during the vulcanization of the two layers 11A and 11B between them.
- the tubular pockets 12 are formed by providing areas of the double ply textile support on which the two folds of the double-fold textile backing are not bonded to each other.
- the successive tubular pockets 12 are spaced from each other by a separation distance d1 substantially equal to 150 millimeters.
- This distance dl provides good flexibility: it allows the winding of the coating 100 on itself, and a good resistance.
- These pockets 12 are provided, as illustrated in FIG. 2b, for the insertion into each tubular pocket 12 of a stiffening bar 20 made of a composite material, this allowing a significant increase in the motor capacity and the lift of the surface S when the surface coating 100 is positioned on the surface S.

- the outer face of the two layers 11A and 11B has a cavity 13 made directly in the elastomer to improve the traction of the surface coating 100.
- imprint 13 may take various forms which are illustrated in a non-limiting manner in these figures 4a to 4c.
- the surface coating 100 comprises a centering strip 50 which makes it possible to reinforce the rigidity of the coating, and which also makes it possible to visualize the central axis of the coating, this being useful in particular for the driver vehicle V must maintain the sometimes unstable balance of his vehicle rolling well in the middle of the coating.
- the surface coating 100 comprises anchoring means 30 consisting of a plurality of metal inserts 31 positioned on the periphery of the surface coating 100 to allow the anchoring of said coating 100 with an element such as a metal pile P embedded in the surface S.
- the operator deploys the coating 100 (which is previously wound on itself), and attaches the coating 100 to the ground S by inserting the piles metal P in the various inserts 31 planted in the ground S. This stabilizes the coating 100 relative to a soil S which is often loose.
- the surface coating 100 comprises on its periphery gripping means 40 such as handles.
- the solution provided by the present invention provides a surface coating of a new kind, such a coating being manageable, simple to implement, lightweight, and compact.
- a surface coating is designed whose covered faces are covered with layers made of different materials, whose stiffening bars have different properties and dimensions, the distances between the pockets tubulars are not identical over the entire coating.
