Dry Concrete Around The Swimming Pool - Mountfield IBIZA Montageanleitung

5 Dry concrete around the
swimming pool
Dry lean concrete should be poured around a circular
swimming pool to fill completely the inground part.
For oval swimming pools it is sufficient to pour the
concrete around the two front sides and rounded pool
parts. No lean concrete needs to be poured behind
the retaining walls. Once the installation is complete,
fill the swimming pool with water. A circular swimming
pool can be completely filled. An oval swimming pool
should be filled stepwise along with the outer filling.
Prior to pouring concrete, put a construction sheet
and polystyrene boards 15-25 mm thick into the
ground at the rounded pool segments to protect the
outer side of the steel wall.
Pour several layers (each ≤50 cm high) of wet lean
concrete C8/10 (or in the mixing ratio of
approximately 1:10 depending on the gravel grain
size) around the swimming pool wall. Each layer must
set before a next layer is added. Formwork panels or
the like can be used to confine the concrete layer
sides. Once the layer has set, the panels are put
upwards for confining the next layer.
While the concrete is poured around the rounded
faces of an oval swimming pool, earth must also be
poured and compacted behind the retaining walls to
help the brickwork absorb the pressure of the water.
The concrete must not be too wet and must not be
shaken or compacted.
Where natural soil (e.g. cohesive clay) is present, the
concrete must be ≥15 cm thick.
Concrete thickness approximately 30 cm is
recommended for calibrated soils.
Professional hint: As an alternative to
concrete pouring, the rounded parts of the
swimming pool can be surrounded with
brickwork and the outer space can be then
backfilled with soil and compacted.
Where poured concrete is used, the
water level must be ≥30 cm higher than
the outer concrete filling in order to
absorb the external pressure.

While pouring concrete around the swimming pool,
make sure that the swimming pool is not deformed by
the pressure of the concrete.
Also, avoid too much concrete pressure on the
skimmer, this might result in distortion and jam of the
skimmer flap. Use of, e.g., polystyrene around the
skimmer is recommended to absorb the pressure
from the concrete at that point. Also, avoid damaging
the steel wall, any damage may result in steel
corrosion later. Also, the warranty would become void
and null. If any scratches and other flaws are present
on the steel wall, treat them with an anticorrosion
agent promptly.
