A foam pit cover having a cover sheet with a gator clip along its perimeter, a perimeter skirt, an apron, and a plurality of toggle bungee cords. The perimeter skirt is made of primary and second sheets, the primary sheet being longer than the secondary sheet. The toggle bungee cords are configured to fit within grommets in the secondary sheet of the perimeter skirt and the bottom part of the apron. The top part of the apron is attached to the bottom part of the primary sheet of the perimeter skirt. The cover sheet and apron are made of a PVC-coated polyester material, and the perimeter skirt is made of a breathable, durable fabric. The invention optionally includes a top sheet with customized graphics and corner pieces to further secure the cover sheet to the perimeter skirt.

A method of providing a snow storage with heat-insulation, the method including covering a snow pile made at a snow storage site with heat-insulating materials of which at least some are insulation boards. In the method, the insulation of the snow pile is carried out by using insulation board mats which include several insulation boards, or insulation board groups consisting of several insulation boards attached against each other, side by side and/or one after another, and which are pivotably joined together, alternately at the upper corners and the lower corners of their opposite transversal end edges, the resulting continuous insulation board mat composed of several insulation boards one after another being foldable into an accordion-like insulation board bundle and re-openable into a continuous insulation board mat. The invention also relates to equipment for providing a snow storage with heat-insulation.

A roller apparatus (102) is provided including roller means (104), drive means (110) for driving rotation of the roller means in use, and an electrical power source for providing electrical power to the drive means in use. The electrical power source is provided by one or more batteries (112) located internally of the roller means.

A rolling-unrolling device for a protective cover for covering a surface to be protected is presented. The device is self-propelling and includes a braking system for blocking the rotation of at least one drive wheel of the carriages and causing the cover to be automatically tensioned during the rolling up thereof on the roller tube. This braking system includes a movable pawl integral with each of the carriages, and a ratchet wheel integral with the drive wheel of each of the carriages, such that, in the direction of rotation corresponding to the unrolling of the cover, the pawl is not engaged with the ratchet wheel and the braking system is in the passive position, and in the opposite direction of rotation corresponding to the rolling up of the cover, the pawl is engaged with the ratchet wheel and the braking system is in the active position.

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.
