A sheathing layer spans a supporting surface from which moisture is to be removed. In one exemplary system, ventilation channels extend between opposed ends of the substrate layer, communicating with an outlet opening at one end and with a duct at the opposing end which in turn communicates with an inlet opening at the same end of the substrate layer as the outlet opening. A fan is arranged to circulate air through channels from the inlet opening to the outlet opening to replace humid air in the channels with drier replacement air. In another example, a substrate layer includes ventilation channels communicating only between the supporting surface and an outlet opening. The outlet opening connects to a fan which maintains the channels at a vacuum pressure to withdraw moisture therefrom.

The invention claimed is: 1. A moisture removal system for removing moisture from a supporting surface, the system comprising:a sheathing layer arranged to span the supporting surface, the sheathing layer comprising:first and second sides edges extending in a longitudinal direction between opposed inlet and outlet ends of the sheathing layer;a rear side arranged for abutment with the supporting surface;an inlet plenum at the inlet end of the sheathing layer;an outlet plenum at the outlet end of the sheathing layer;a plurality of channels extending in the longitudinal direction in communication between the inlet plenum and the outlet plenum;the channels being arranged to communicate with the supporting surface through the rear side of the sheathing layer;an inlet passage communicating between one of the ends of the sheathing layer and an inlet opening of the sheathing layer;an outlet passage communicating between said one of the ends of the sheathing layer and an outlet opening of the sheathing layer such that the outlet opening and the inlet opening are located at the same one of the ends of the sheathing layer;a fan arranged to circulate air through the channels from the inlet opening to the outlet opening of the sheathing layer; anda controller arranged to operate the fan so as to be arranged for replacing humid air in the channels with replacement air which is drier than the humid air.
