Installation
As the Hebden 40 is
quite light, it is very easy to install and can be laid at the rate
of around 75m2 per person per hour.
The installation
guidelines below are suitable for most applications. If in doubt,
feel free to ask us.
Mark out
the area to be covered with the Hebden 40s adding around
15cm extra all around. Excavate the full marked area to the
following depth below the required top surface of the Grass
Paving.
Garage Driveways :-25cm, Parking Area :-30cm, Emergency
Access :-45cm or Heavy Trucks :-60cm. |
With the
full area excavated, compact the whole area and install a
permanent perimeter fringe at the points that vehicles
access the paving.
The support layer of Granular Class A Gravel to within 8 to
10cm Grade can be placed on top of this compacted area to a
depth of the following: Garage Driveways 22cms, Parking Area
27cms, Emergency Access 45cms and Heavy Trucks 50cms. |
| Compact
the Class A Gravel and then put a 4cm thick layer of sand on
top. The sand needs to be levelled accurately with a spirit
level and smoothed down. When the finished area is to be
grassed over we recommend the sand be replaced with a sieved
50/50 mix of sand and compost. |
| Interlock
and set the Hebden 40s in straight lines and ensure that
they are all going in the same direction. Any Hebden 40s
needing cutting should be measured and cut with a saw
before attempting installation with the Hebden 40 being cut
to leave solid enclosed chambers on the edge wherever
possible. With all the Hebden 40s in the correct position
slightly compact them onto the sand and ensure they remain
flat and level. If the ground is sloping, we recommend the
top edge pavers be
further held with 3 stakes per meter at this stage. |
| The Hebden
40s can now be filled with the required medium of either
gravel or a mixture of compost and top soil
with grass seed sown in. Wash in the mixed substrate to a
level 5mm beneath the top of the ecopaving which will
protect the grass whilst it becomes established. |
