Installation

Before installing TriNet TRMs, the seedbed shall be inspected by the Owner’s Representative to ensure it has been properly compacted and fine graded to remove any existing rills. It shall be free of obstructions, such as tree roots, projections such as stones, and other foreign objects. Grass seed shall match soil conditions to allow for maximum germination, dense vegetation, and a structural root system. Contractor shall proceed when satisfactory conditions are present. After the area has been properly shaped, seeded, fertilized, and compacted, locate the start of the roll, making sure the roll is facing toward the area to be covered, and then roll out the TRM. TriNet TRMs shall be rolled out flat, even, and smooth without stretching the material then anchored to the subgrade.

Slopes: It is recommended the TRM be installed vertically on the slope; however, on short slopes, it may be more practical to install horizontally across the width of the application when agreed upon by the Engineer prior to installation. If more than one width is required, overlap the edges of the vertically installed TRMs and secure the TRMs with a common row of staples. TriNet  TRMs shall be trenched at the head of the slope if the blanket cannot be extended three feet over the slope crest or if overland flow is anticipated from upslope areas.

Channels: TriNet TRMs shall be centered to offset a seam in the middle of the waterway. They shall be installed in the same direction as the water flow. The adjoining TRMs shall be installed away from the center of the channel and overlapped. TriNet TRM installation should continue up the side slopes three feet above the anticipated high water elevation. Flanks exposed to runoff, or sheet flow, must be trenched in. TriNet TRM shall be trenched at the start of channels. TriNet TRM shall be anchored using a staggered staple pattern at end of roll overlaps and end of roll terminations.
