A finished flooring underlayment is disclosed including a flexible membrane which is resistant to water, mold and deterioration under wet or dry conditions, and which has intertwined filaments bonded to the membrane surface that act as mortar reinforcement and as gauges to provide a uniform thickness of application for cementicious mortar. The mortar is provided separately and is mixed to a suitable consistency with either water or latex additive, then poured or placed on the mat, utilizing the gauges provided by the filaments to effect a uniform thickness of application. This mortar hardens to a strong, load bearing surface or slab suitable for application of finished flooring.

[ What is claimed is:] [1.] A composite finished flooring underlayment mat for use in installing finished flooring over a subfloor unsuitable for direct application of finished flooring, the composite mat comprisinga flexible membrane,a flexible mesh overlying the membrane, the mesh being an entanglement of irregularly spaced filaments intertwined in a form-sustaining unitary body providing mortar reinforcement and a generally uniform height preselected to correspond to a desired underlayment thickness, and a mortar filling interstices of the mesh and forming a load bearing slab having a generally uniform thickness predetermined by the height of the mesh.
