Starting with landscape design

Building raised backyard ponds using preformed
pond liners - installation
techniques to suit your landscape design ideas
landscape design ideas: Showing footings
for the blockwork that will support the pool liner and the facing stone.
Landscape design ideas
If the backyard water garden or garden pool is going to be raised or
partially raised:
- Place the pool liner in position and
mark out the shape on the ground around it.
- Carefully remove any turf within the
shape and excavate to a level soil surface slightly larger than the
shape. A long spirit level, or a spirit level with a long straight edge
is essential.
- The shape of the pool to satisfy your
landscape design ideas must be marked on the ground plumb with the
outside edge.
- From this line inwards 2 ins (5cm) and
outwards by possibly 4 inches (10cm) a small 4 inch (10cm) deep trench
for a footing must be excavated and filled with a semi-dry concrete 5:1
mix of 'All-in' ballast and cement powder.
- The width of the footing depends
ultimately on the thickness of the facing stone or brick that the water
feature is intended to have.
- If the pool is to be partially set in
the ground (landscape design ideas?), the base of the pool should be
marked on the ground and the resulting shape excavated to the required
depth at which the base should be flattened and levelled.
Landscape design ideas:
Concrete blocks laid in place
to support the fibreglass pool and the facing stone
|
-
A 4inch (10cm)
concrete block wall will be built up to support the rim of the pool. A
single line of concrete blocks is sufficient to support the pool out of the
ground at marginal shelf level. The depth of a standard concrete block (9ins
or 23cm with mortar) generally corresponds the depth of most manufacture's
pools at the marginal shelf. Two high, they correspond to the complete depth
to the base. Slight variations can be taken up with a layer of brickwork or
thick mortar joints. Leave the vertical joints of the block work partly open
to begin with, in order to facilitate the backfilling with sand.
-
With the block work
in place, replace the liner on a thin 1 inch (25mm) cushion of sand. If it
seems well supported fill it with water. Flimsy liners can filled to the
marginal shelf level.
-
Leave it there full
of water over night to do any settling that might occur, before you attempt
any edging. If it shifts - empty it and build up the sand support where it
has sunk. Gently ramming down the backfill further at the lowest point can
make up tiny fractions in subsidence. If you need to do this don't overdo it
because it can buckle up the rim of the liner, which you want to keep as
flat as possible to take whatever edging you might want to choose to go
round it. As you backfill the pointing to the upper parts of the blockwork
must be completed
-
The facing
stonework to the pool can be started at any point using the blockwork as
support. You could alternatively use a wider block (6inch or 15cm) and just
render the face of the blocks with cement. With the stonework built level,
and edge can be laid in place. 'Profile edging' or segment paving saves
cutting slabs, or in natural stone, crazy paving is most popular.
-
That's it your
landscape design ideas now complete.
