  BEFORE YOU BEGIN

  Storage
  Matting rolls should be stored in their original, unopened packaging. The designated storage area should be
  level, dry, well-drained, stable, and should protect the product from:
  •   Precipitation;
  •   Chemicals;
  •   Standing water;
  •   Excessive heat;
  •   Ultraviolet radiation;
  •   Vandalism and animals.

  Biodegrabale matting such as jute should not exposed to moisture prior to installation as this can cause
  premature degradation. Damaged wrappers should immediately be repaired with weather resistant tape.
  Wrapping should only be removed from rolls immediately prior to installation.


  What You'll Need On Site
  Prior to commencement of installation the following equipment will be required:
  •   Carpet knife, safety knife or scissors;
  •   Hammer or mallet;
  •   Spade or digger for trenching.



  PREPARING THE SURFACE
  •   It is recommended that weed affected areas are sprayed with herbicide prior to mat installation.
  •   Excavate and trim slope to smooth profile, removing obstructions such as tree stumps or rubble and filling in
      any voids. The smoother the surface, the better contact between soil and matting.
  •   Excavate anchor trenches along the top edge as specified.
  •   Top soil is required to successfully grow grass and plants. Evenly spread top soil across the surface to required
      depth.
  •   All pre-seeding of the soil to be carried out prior to laying Grassroots and Biomac.



  TRENCHING
  •   A trench is necessary on gradients of 1:3 or steeper and in riparian or flood areas.     Lay matting into a
  •   Dig a trench at the top of the slope, minimum width and depth of 150 mm.                 trench of a minimum
                                                                                               150 mm wide and
  •   Pin the end of the roll into the bottom of the trench at 300 mm intervals.               deep, pin and backfill
  •   Back-fill the trench and roll the matting down the slope with a minimum overlap             150 mm

      of 150 mm.
  •   Pin material ensuring the overlaps are secured well.
  •   Trenches should be deeper for channels and slopes steeper than 1:1.
