The 'surface covering' has means to maintain its position in loose, unstable, easily penetrated substratum, using tube pegs, 'envelopes', or a down-turned edge or edges/fin or fins; with versions made from a range of materials of various flexibilities/strength. The 'surface covering' in one embodiment is smooth, used as a slide, and has versions that can be multi or single lane, various lengths, one piece, or requiring assembly from a plurality of pieces or units, which may overlap other units to create various length slides, hi the inventions pathway/cycleway embodiment each individual unit may also be physically linked at the point of overlap and the surface be of a non-slip nature.
