Waterman Basic - CASTING THE CONCRETE SLAB

Assembly and Operating Instructions 'Basic' Pools
English
23
Attention: Oval basins may only be
installed as (complete) inground pools.
An above-ground installation is not
possible for static reasons. Never build landlls
in case of slopes. Slopes must be levelled by
means of excavation. Slopes must be supported
by retaining walls, or be strongly attened.
Under no circumstances can the basin support
a slope. In case of accumulating groundwater or
layer groundwater, a drainage must be provided.
The excavation pit must not be located in the
groundwater area.
Pool setup (oval pools)
Before setting the pool up, check that all required parts are available according to the attached parts list:

DIMENSIONS OF EXCAVATION
For a pool depth of 1.20 m, the excavation should be
at least 100-120 cm deep (plus the additional depth
required for the oor/concrete slab).
The soil/ground oor in the excavation area must
meet the static requirements. It must be natural soil
and never consist of backlled soil. The dimensions
of the excavation pit are shown in the following
drawing/table.
CASTING THE CONCRETE SLAB
We recommend that you use an approx. 15 cm
thick layer of gravel underneath the concrete
slab as drainage/frost blanket. The concrete slab
should be at least 10 to 15 cm thick and should in
any case be reinforced with an iron reinforcement/
steel fabric mat (Q188 A). In the area where the
retaining walls are to be built, integrate additional
iron reinforcements/round iron bars, which will later
connect the concrete slab and the lateral retaining
walls. The concrete slab must have an additional
depth of at least 16 cm in the area where the
retaining walls will be built later (this means a total
depth of approx. 31 cm).
