Approved Plan - Landscape Specification prepared by URBIS - OPW24/0110

The following instructions apply to all grades of Grassroots, Biomac and Jute.

¢ The material should be rolled from top to bottom of steep batters, as opposed to across the batter. The
material may sag between fastening pins if laid across steep slopes.

¢ Minimum overlap of 150 mm is recommended. Overlaps should be pinned at 300 mm intervals.

¢ The matting should be laid down the flow line in swale drains. The leading edges should be trenched and
overlaps must follow the flow line downstream.

e — Sites subject to flooding require the laying pattern to mimic a fish-scale pattern. The material should be laid so
that the leading edges are not exposed to water flow.

¢  Donot pull the material tightly across the soil surface. Allow it to contour to the soil profile and into
undulations. This allows the material to settle and bond with the topsoil.

e If the site requires the matting to be laid across slopes, then the top edge should be trenched and pinned at a
higher rate.
