A device for covering a surface includes (a) a covering, each longitudinal edge of which is provided with a projecting element; (b) a rotatably mounted drum suitable for rolling up or unrolling the covering, and movable in translation on rails placed on either side of the surface; (c) a system for continuously locking/unlocking the projecting element in the rails during the translation of the drum. The projecting element includes a multitude of discreet elements distributed along each longitudinal edge separated from one another by an average distance (d).

A method of installing a binder-based overlay system may include contacting a layer of geotextile fabric to a surface of a substrate and applying a primer layer to a surface of the geotextile fabric. Two or more binder layers including infill particles may be applied over the primer layer. A resurfacer layer followed by one or more color layers may be applied over the two or more binder layers. The primer layer, one or more binder layers, resurfacer layer, and two or more color layers may cure upon application to form a monolithic layer upon the substrate.

A device for covering a surface including a substantially rectangular cover (10) having first and second longitudinal edges each provided with a protruding convex bead (12) having a minimum diameter (d), two rails (6) including a groove, the opening (14) of which has a maximum width (Lo), a drum (2) that is able to move above the surface in order to deploy or retrieve the cover, an insertion system (16) for continuous insertion of the convex bead (12) into the groove. The convex bead (12) of each longitudinal edge and the groove of the corresponding rail are configured such that, once inserted into the space (14e) by the insertion system, the convex bead occupying the space alone cannot be removed solely by the action of a force (F) applied parallel to the transverse axis (Y) in the direction of the surface to be covered.

A system for reversibly converting stadiums into multifunctional infrastructure by removing the pitch and storing it in a pit (6), the pitch having a set of trays (1) having a total length equal to the pitch in a longitudinal direction of the pit, which are moveable, self-supporting and have layers of soil, irrigation and turf; a set of transport trolleys (2) for lifting and moving each tray (1) from its position on the pitch to the pit (6); a set of retractable trellises (5) that can be unfolded on the pit (6), for the entry of each tray (1) from above the pit; an elevator system (8) inside the pit (6) to move each tray to its final position, in storage, or on the pitch; and a storage system (7) for storing each tray in a fixed and stable position.

The present disclosure concerns a flexible thermal insulation assembly to thermally insulate matter from an external environment, the flexible thermal insulation assembly comprising a plurality of thermal insulation covering sections comprising an outer layer and an insulated matter-facing layer, the plurality of thermal insulation covering sections being configurable in an adjacent configuration wherein the plurality of thermal insulation covering sections are articulately connected to one another to substantially conform to an outer surface of the insulated matter; and an insulated matter-mounting assembly securing the plurality of thermal insulation covering sections onto the insulated matter with the insulated matter-facing layers of the plurality of thermal insulation covering sections at least partially covering the insulated matter and substantially conforming thereto. The present disclosure also concerns a method for thermally insulating matter, such as a snow heap, from an external environment.
