Abstract
An apparatus for forming a foamed outdoor protective cover layer having a storage tank adapted to contain a slurry. A pump is connected to the storage tank for supplying slurry from the tank to a first inlet port of a regulating valve. A foam generator is connected to a second inlet port of the regulating valve. The regulating valve also includes an outlet port which is connected to a spray nozzle. The regulating valve is operable to combine foam produced by the foam generator with pumped slurry to produce a foamed composition. The regulating valve is adjustable to vary the rate of addition of foam to the pumped slurry to control the density of the foamed composition.
