cover the reinforcing ring structure was either fabricated in sections corresponding to the cuts to be made or such ring structure was severed at the time the transverse cuts were made for segmenting the foam cover when the cover is reassembled at the pool site the reinforcing rings 45 are welded together to provide a continuous ring after such welding additional foam material is filled in around the region of the welds the reassembled cover is coated with the protective coating 24 as of fibrous concrete or fiberglass referring now to fig1 and 13 there is shown an alternative embodiment of the present invention in the pool cover 11 of fig1 and 13 the reinforcing wire mesh is embedded in the foam to provide increased strength and rigidity for the cover more particularly a vertical grid pattern of reinforcing steel wire mesh 61 is laid on top of a first wire mesh 62 which is laid out horizontally on top of an initial layer of plastic foam formed upon the surface of the pool the vertically directed intersecting wire meshes 61 are secured as by wiring welding or the like to the bottom horizontal mesh 62 additional foam is then applied to embed the lower mesh 62 in the foam and to embed a portion of each of the vertically directed meshes 61 in the foam air inflated plastic bags 63 are then laid into the space between the intersecting vertical meshes 61 and foam is applied so as to embed the bags 63 in the thickness of the cover a second horizontal reinforcing wire mesh 64 is then laid on top of the foamed bags 63 and anchored to the vertical meshes 61 as.
