Stage 4 - Compaction
Once the cells are filled (or slightly over filled depending
on fill material) the frame is removed and the fill
compacted. A mechanical plate compactor is ideal.
This can be carried out whilst the excavator is filling
the next frame however you must ensure that the
compactor does not enter into the excavator bucket
operating radius at any time.
Compaction of the material is achieved with three passes
of a plate compactor.
Note:
Care must be taken not to over compact otherwise
the outer cell walls may be crushed which will affect the
overall cell/berm height.
If the level of fill is too high once compaction is complete
this must be removed before the next layer is laid.
Stage 5 - Subsequent Layers
Once the base level is complete or you have finished a
section (depending on your construction plan) move to
the next layer.
Using frame
First change the frame to the next size down as per the
frame guide. Place on the fabric panel as previously
instructed.
Position the frame on top of the layer below, checking
it is central to the berm. This will give you spacing of
160mm either side of the panel below or roughly half a
cell. Position the end directly in line with the layer below.
Using pins
Pins are placed in the outer cells of the filled layer.
Position them centrally in the cell and step back half
a cell (160mm) from the edge to achieve the desired
angle/profile required for the berm.
Note:
It is recommended that sequential panels are laid
to maintain momentum of the filling process.
Panel joints. Profile 300 1.25m
Stagger panel joints by using half panels at each end of
the berm to create an interlock between the panels.
Note:
Half panels are required on layers 2 and 4
