Important: If the filter system is not
located immediately at the swimming
pool, trenches for the piping must be
excavated simultaneously. The trenches
should be about 40–50 cm wide and
about 100 cm deep. If the option to
completely drain the piping before the
winter season exists, the pipes can be
laid higher, inclined downwards to the
(lowest-lying) draining point.
For this we recommend preparing a large (160 mm in
diameter or larger) plastic or similar pipe at the
appropriate site.
If required, trenches can also be excavated for piping
from the filter system to a solar heating system and
for power supply cables.

Once the earth excavating and water draining (after
gravel layer laying if necessary) operations have
been completed, the concrete base slab (C16/20)
with reinforcement (Q188A construction steel mesh)
is fabricated. The recommended base slab thickness
is about 15 cm: the actual thickness (and the gravel
layer thickness) should be determined by a
specialized civil engineer.
The base slab should be laid precisely
horizontally, with no gradient, and its edges
should overreach the swimming pool edges
by some 10 cm.

Once again, the base slab can be rectangular or
circular/oval (copying the swimming pool shape).
Important: Embedding the steel
reinforcement immediately into the wet
base slab is recommended. The
reinforcement consists of 8mm
construction steel bars with bends, laid
at a spacing of approximately 25 x 50 cm.
Best take one of the hollow blocks to be used for the
retaining wall and imprint the patterns of the later wall
into the wet concrete. Put a bent steel rebar centrally
into each of the now visible internal chambers of the
imprints (Fig. 10).
