Uniform Cross Section or Unimat
(3"UM, 4"UM, 6"UM, 8"UM)

The surface of the Unimat style is slightly dimpled. The thickness of the Unimat is created by spacer cords that connect the top layer and bottom layer of fabric together, thus, giving the dimpled surface. The revetment's low coefficient of hydraulic friction and permeability is equivalent to that of high quality concrete paving. In selecting the Unimat thickness required, the same criteria for determining the thickness of conventional concrete paving is employed. Where relief of hydrostatic uplift is required, weep hole assemblies can be installed through the fabric.

3" & 4" Unimat
The 3" UM & 4"UM are the lightest styles of Unimat. They are used for light-duty concrete paving. Criteria for selecting the 3"UM or 4"UM are the same as 3" & 4" conventional concrete paving.

6" Unimat
The most frequently used size of Unimat, the 6"UM, is very versatile when greater weight and impermeability is required. Criteria for selecting the 6"UM are the same as 6" conventional concrete paving.

8" Unimat
The largest in the Unimat style, the 8"UM, is used where greater weight and protection is required. Sizes larger than the 8”UM are available upon request.

Some areas of installation are: leachate & retention ponds, trapezoidal ditches, canals, down drains and perimeter ditches on landfills, reservoirs and lakes, boat ramps, bridge abutments, low-level water control structures & dams.
