and then adjust horizontal alignment of these
panels

Fill should be placed by plant such as an
excavator bucket or a dozer with an opening
bucket which causes the fill to cascade onto the
grids. A minimum of 150 mm thick cover of fill
must be maintained between the tracks of any
plant and the grid to avoid damage. Use plant
with a total mass less than 1000 kg within 2 m
of the face

Apply a load to the free end of the grid using a
tensioning beam (see TN/SRREBeam) inserted
through the apertures in the grid, until the slack
is removed from the joint.Whilst maintaining
tension, place a layer of fill on the grid, which is
sufficient to restrain it in position when the load
is released. Release the tension and remove the
beam
Folding and slack in the geogrid is not allowed.
