Uniform Section Mat

It is formed with a double-layer woven fabric, joined together by spacer cords on closely spaced centers to produce a mat of uniform thickness. Similar to traditional concrete slope paving, USM creates a solid, high-quality concrete lining with low hydraulic resistance for use in various lining and erosion resistance applications.

Form a lining of required nominal thickness, bonded cobbled surface, and specified weight to provide strength and erosion protection to resist the calculated tractive forces. The design criterion for the selection of lining thickness is the same as that used to determine the thickness of conventional concrete slope paving. Relief of hydrostatic uplift pressure may be provided by inserting plastic weep tubes through the mat at specified centers. USM is custom fabricated into multiple mill width panels, designed to fit actual site dimensions and topography.
