Maximum slope 1.5:1 horiz:vert, (67% or 34) or flatter, and is limited to slopes < 30' of uninterrupted length. When specified, ensure coloring is added to the concrete. Rock Slope Protection practice is intended for slopes too unstable for revegetation practices alone. When slope protection is paid by volume, review the plans and quantity calculations in the resident engineers file to determine if there is sufficient detail and accuracy to be used in the project records. To better control the contractors selection of rocks for placing, ensure the contractor paints tonnage on large rocks used in foundation construction.

Method B is not restrictive with respect to the placement of individual rocks. (You may enter part of the word or the whole phrase). (b) Paving fabric specification requires a minimum mass of 4.1 sy/oz. Where applicable, inspect the footing areas and foundations for evidence of instability or areas where hydrostatic pressures may develop. To ensure the success of Method A, ensure that the bearing of rocks from one to the other follows specifications and that the use of chinking rocks is limited to filling voids. Flat or needle shaped rock must not be used unless the individual rock thickness is greater than 0.33 times the length. Flat or needle shaped rock must not be used unless the individual rock thickness is greater than 0.33 times the length. Also, ensure the contractor does not drop rock into place; otherwise, cracking or breaking may occur. Need quick pricing on Erosion Control Fabric?
