2. Excavation Depth – Calculation.
Determine the depth of the pool excavation and of the excavation for placing the technology shaft
according to the calculations below. First determine the total depth of the pool excavation. The depth
of the excavation for the technology shaft (counterflow shaft) should be determined afterwards. The
height of the step (E) for the correct placement of the technology shaft should be determined at the
end. Please remember to account for the dierence from the raised terrain (U). The value “U” directly
addresses the final height of the complete construction of the pool; therefore it is necessary to take
into account all the construction steps performed subsequently (raised paving, recessing or raising
the pool, etc.).
The upper edge of the technology shaft should be set to at least 40mm (F) above the planned final
surface around the pool (make sure it does not collide with the travelling front of the roof). This is due
to the need to protect the shaft from rainwater. If you do not want to have the shaft elevated above
the final surface level, adequate drainage of rainwater must be provided around the shaft. The shaft
must not be located where the future rails for the roof will be installed. The bottom of the shaft is
intentionally kept without thermal insulation so that the shaft is naturally ‘heated’ in the winter from
the soil below.

2.2. Surveying and excavation
Excavation and Securing the Perimeter Walls.
Excavation and securing of the perimeter walls of the pit (if necessary because of the geological conditions)
should be carried out exclusively by a specialized company. The excavated soil can be used for landscaping
around the pool; you can count on the majority of the soil being used this way. This means there is no need
to dump the soil. Landscaping around the pool refers to the pool as a new structure; not always necessary.
The aforementioned data and calculations apply to the standard location of the technology shaft –
see plan view of excavation.
Note:
Along with the earthworks and excavation, consider connecting the pool to the sewage and rainwater
system on the premises. This will enable the drainage pump and pool technology to be connected
directly to the drainage, which gives you more comfort in pool maintenance, for example, when
draining water from the filter, etc.
The following types of technology shafts may be included in the scope of the con-
tract for work:
Technology shaft with cover for installation of filtration (Ø 1200, height 1200 mm)
Technology shaft with cover for installation of filtration and counterflow (Ø 1500, height 1200 mm)
Technology shaft with cover for counterflow installation (1200 x 600 x 800 mm) = L/W/H

Preparations for Placement of Miscellaneous Pool Technology.
Another possible location of the technology is oered by using the ALBIXON technology wall, in its own
dedicated shaft or in any other place (service room, garden house…). The pool technology should be placed in a
room with limited access (protected against unauthorized persons or children), where the ambient temperature
does not exceed 40 °C and where the ambient humidity is suitable for the needs of electrical components.
Where the technology is placed above the water level in
the pool, a maintenance (disconnecting) drain shaft should
be created. Maintenance shaft for convenient disconnection
of fittings. The disconnect at the lowest point must enable
draining all water from the shaft system used to drain water
fromthepipingfor winter. Thedimensions ofthe maintenance
shaft should be of at least 500 x 500 mm (subject to the
depth) and the depth should be adequate to the pipe route,
however always allowing for the convenient disconnection of
the pipes and discharge of water. For the location of the disconnect fitting, see the picture. The disconnect must
be placed at the lowest point of the piping.
Technology wall (left, right) – a technological unit designed to be
placed in a service room or in other suitable garden structure. The
wall must be placed on a horizontal and sufficiently rigid base. On the
side of the outlets (left or right), it is necessary to leave at least 500 mm
of space for connections and further handling. To connect the pool
technology and the pool and – if applicable – external heating, make
sure to prepare pipeline routes and penetrations of the appropriate
size (pipe Ø + insulation) into the technology installation space. This
also applies to technology that is installed atypically.
Install the counterflow device separately in the counterflow shaft or in the technology shaft. The counterflow
shaft should be positioned so that the counterflow pipe from the shaft is aligned with the pool axis and runs towards
the outlets of the counterflow body placed on the pool shell. This is to achieve the lowest power losses. The
maximum distance from the exterior contour of the pool shell is 2000 mm. If the counterflow is not aligned with
the axis of the pool shell, its performance will be diminished.
Heat pump – to connect the pool technology and the heat
pump, it is necessary to create routes for laying the connecting
pipe (excavation width 200 mm at minimum, pipe slope 1.5 °
along its entire length towards the shaft). To connect the heat
pump and the technology wall, it is necessary to place the
disconnectors for water discharge in the maintenance drain
shaftat thelowest pointof thepipe. Theheat pumpfoundation
slab must be suciently firm and level (a concrete foundation
150mm high with floor plan dimensions that exceed those of
the heat pump by at least 40mm on each side). Install the heat pump in a spacious and sunny location with good
ventilation. Its position must allow for smooth air circulation; see the instructions for the respective heat pump.
During its operation, the heat pump may produce a considerable amount of water condensate. This needs to be
accounted for and drainage must be provided. Ensure that after installation the device is in an upright position
without any tilt. Do not install the device in places with the presence of contamination or corrosive gases, or where
dirt or fallen leaves collect. The place where it is installed must not be near flammable or explosive environments
with usual fire hazards. Observe distances from obstacles, always in accordance with the respective heat pump
manual. Install the heat pump at least 3500 mm from the edge of the pool (according to ČSN 33 2000-7-702)
and up to 7500 mm from the pool technology and with a vertical dierence of up to 1000 mm between the
water level in the pool and the bottom edge of the heat pump. This installation does not result in an excessive
decrease in the performance of the circulation pump and does not cause heat loss in the longer piping.

1. Installation of earth strip and drainage set – 1st Stage.
An earth strip in accordance with the applicable standards must be installed at the bottom of the excavation.
For more details on electrical wiring, see the Electrical Wiring section.
The foundation slab must be permanently drained. For proper drainage of the foundation slab, it is necessary
to install drainage piping under the foundation; the piping should be connected to a drainage set (for drainage
pump shaft + drainage pump permanently connected to a power supply, see the following paragraph).
Ask your construction company for the ideal design of draining the pool foundation slab and any shafts,
according to the local geological conditions. Be sure, though, to account not only for groundwater but also
for rainwater, which may have equally negative eects on the pool shell as a whole, such as groundwater.
`
Drainage pump shaft – a pipe
with a diameter of approx. 300 mm placed
vertically next to the foundation slab. Pour gravel
with an 8-to-16-mm grain size onto the bottom
of this pipe. There must be a height dierence of at
least 500 mm between the gravel and the final
level of the pool foundation slab. The drainage
pump shaft serves as a sump for collecting
groundwater and rainwater. It must be provided
with a submersible pump. This pump must
trigger automatically when the water level in the
shaft rises and must be permanently connected
to the power supply via an underground cable.
The supply cable must run from the house
switchboard, and yet it must not be connected
through the switchboard in the technology
shaft. The pumped water must flow out of the
pool area and must not return under the pool
(see note on page 6 regarding the sewage and
rainwater system).
2. Backfilling with Gravel and Drainage Piping Installation, 2nd Stage.
Spread gravel with an 8–16mm grain size to form a layer about 100 mm thick the bottom of the
excavation. The 80-mm drainage piping is to be laid in the gravel layer, sloped down towards the
water outlet point (drainage pump shaft). The drainage pipe must be laid with a minimum slope of 1%.
In the layout, the mutual distances between the drainage pipes must not be greater than 800 mm.
All drainage pipes must be covered with a special geotextile before being overlaid with gravel and
concrete

3. Final Covering with Gravel, 3rd Stage.
Lay another approx. 100-mm-thick layer of gravel (grain size 8–16 mm) on top of the first layer of gravel with
the laid drainage pipes covered with geotextile. The gravel needs to be adequately compacted, but be careful
not to damage the drainage pipes.

Important notice:
Drainage of the foundation slabs is an essential part of the construction preparation.
Rainwater and/or groundwater can cause quite extensive deformations of the pool shell;
therefore the foundation slab of the pool must always be properly drained. If the place for
installing the pool is in sloping terrain, or, after beginning the earthworks, it is found that it
has a clay subsoil (which means a higher probability of groundwater and its exercising of
pressure on the pool body), we recommend that you have a geological survey conducted
for foundation engineering. As a follow-up to its result, we recommend that you take
extended construction and drainage measures in relation to the target site, which will be
implemented outside the actual pool drainage system.
Damage to the pool caused by insufficient or inadequate preparation for construction is
not covered by the right arising from defective performance. Therefore, it is important to
monitor the construction company and its procedures continuously. We recommend
regular photo documentation of all the construction steps.

1. Preparation of formwork for concreting.
Place the formwork on the compacted layer according to the floor plan dimensions on page 4. The formwork
height of 200 mm needs to be adjusted to the other height parameters – page 5. The formwork must be
level. (The specified flatness of the formwork is +/- 2 mm along the entire perimeter. Final inspection of the
backfilled excavation.
2. First Layer of Concrete.
Spread the first layer of concrete into the prepared formwork up to one-third of its height. The reinforcement
will be placed on this layer.
Use C16/20 grade concrete for concreting the foundation slab.
3. Installation of rebar meshes
Reinforce the foundation slab using a rebar mesh with the dimensions of 100 x 100 x 6 mm. It is not
necessary to reinforce the foundation slab under the technology shaft.
4. Second Layer of Concrete (Preparation for Final Layer).
Now, pour a second layer of concrete on the laid rebar mesh, up to the height of the formwork. Level
the surface of the concrete base so that the flatness of the slab is within +- 2 mm across the entire
surface.
5. Final Layer of Concrete.
After at least 48 hours, carry out a flatness check. Apply this layer with a self-levelling cement screed
only if the required flatness in the second layer has not been achieved.
Record the final surveying result in the attached protocol (CUSTOMER’S DECLARATION ON

1. Laying the thermal insulation. 1st Stage
Place thermal insulation (extruded polystyrene, 30 mm in thickness, with a minimum compressive strength of
200 kPa) on the foundation slab, under the bottom of the pool, and secure it against shift.
2. Placing the Pool Shell in the Excavation (in conjunction with the supplier)
2nd Stage
Place the pool shell, in accordance with local conditions. Once the pool has been laid in the excavation, the
customer should check the correct location and approve the fact with the workers installing the pool. The
customer then starts filling the pool with water (about 300 mm) to load it.
3. Technology shaft placement in the excavation

4. Complete installation of the pool technology
Installation of technology and its interconnection via pipes with the pool shell. In order to interconnect
the pool and the technology shaft correctly, it is necessary to have an accurately prepared step for the
shaft in accordance with Chapter 2 Excavation Depth.
5. Tightness test by flooding the technology
The tightness of joints and pipes is verified by performing a “technology flooding”. For this test it
is necessary to ensure a sucient amount of water to fill the technology to a water level of about
300 mm.

tion of the Pool Technology

7.
Bracing the Pool Shell
Before concreting, appropriate bracing needs to be put in place to support the pool shell. The braces are
placed in order to prevent any potential deformations of the pool shell. Deformations may be caused by
careless handling of the concrete (such as when backfilling with concrete that is too thin or when tamping
it), or by too high an added water level. The pool walls must not deform inwards or outwards; the walls must
be flat and vertical. We recommend that you check the wall perpendicularity and flatness and the overall
shape of the pool and its diagonals frequently. We recommend that the shell should always be braced at
the points where reinforcing elements (ribs) are provided. When installing the bracing, care must be taken
not to damage the pool’s interior walls, e.g. by wrapping the braces with geotextile. For rectangular pools,
horizontal bracing must be omitted within a distance of 200–250 mm from the pool’s corners; see below,
highlighted in red.

1. Lining the supporting walls and concreting around the pool shell
Before commencing the lining and concreting works, all elements of the technology (e.g. circulation nozzles,
pipes, fittings, etc.) must be fitted with suitable insulation – for example, MIRELON sleeves with a thickness of
10 mm. This will insulate these components thermally, enable their thermal expansion, and protect them from
damage during concreting.Once the preparation of the pool shell,
technology shaft and counterflow shaft, if any, is complete,
gradual lining of the supporting walls – which separate the
layers of concrete and soil – can begin. The support-
ing walls (150mm in width) can be built after the
pool has been placed in position and its tech-
nologies have been connected. The foun-
dation slab must be suitably joined
with the underpinning wall. When
lining, it is important to main-
tain a sucient distance
(50 mm) between the
retaining wall and the
reinforcing elements
of the pool shell and
the technology shaft
so that it is possible to
backfill this space with
dry concrete. Dry con-
crete must not be packed.
This will prevents the pool shell
from becoming uneven.
During concreting, it is necessary to con-
tinuously check the verticality (perpendicularity)
and flatness of the walls and the identical length of the diagonals of the pool shell. In case of any deviation,
immediately stop the concreting operation and level the shell. Concreting is carried out in layers, keeping the
height of a single layer of concrete to a maximum of 300 mm. After each single layer of concrete is completed,
the next layer is applied only after the previous layer has set. During concreting, it is necessary to gradually add
water to the pool so that the water level is 100 to 200 mm higher than the layer of concrete. The part of the wa-
ter level higher than the concrete de-
pends on the plasticity of the concrete
used. Choose a lower height of the
water level above the concrete for dry
concrete varieties and a higher level
for wet concrete. Do not connect the
pool shell to the lining firmly from the
bottom up to the height of the shell
reinforcing elements where these are
located – see chapter below. Lay the
piping during construction comple-
tion operations in perfectly packed
sand that contains no stones or clay,
and cover it with fine-grained sand
that contains no clay (cover sand bed
of at least 100 mm). It is necessary to proceed in such a way that no damage to the piping occurs e.g. by move-
ments (settling) of insuciently packed subsoil and its surroundings, movements of frozen soil, etc. Vehicles
must not be allowed to drive over places where the piping runs. The remaining surrounding space between the
lining and the ground should be refilled with soil. Pack (compact) this soil carefully. Do not concrete the place
where the counterflow is installed, but only refill it with packed sand.

2. Concreting of Technology Shaft (if part of the contract for work)
The technology shaft is to be fitted with a lining or concreting. The lower part of the technology shaft
must be anchored in concrete and then lined with concrete in a layer about 150 mm thick up to the top
plastic collar, which must be concreted into the base plate for the final surface.The technology shaft can
be protected against damage by geotextile. Depending on local conditions (changes between shade and
sun, etc.), it is necessary to insulate the inner surface of the shaft cover with polystyrene at least 3 cm thick.
This insulation will prevent the precipitation of moisture on the inside of the cover. The interior of the
shaft should be dry and ventilated. To ensure this, place a support under the shaft lid so that air can flow
between the edge of the shaft wall and below the cover. These measures are the responsibility of the user.
Pipes around the technology shaft (or to the service room) must be laid in a sand bed with a minimum
covering of 100 mm above and below the pipe, thanks to which any pressures on the pipe are equalized. The
sand bed must be provided from the duct transition to the technology shaft up to the outlet of the piping
from the pool insulation.
3. Anchoring the walls of the pool shell
Anchor the edge of the pool with 800-mm-long steel rebars (Ø 8 mm) bent at an angle of 90° each 400
mm. The rebars should be pulled through the drilled holes in the edge of the pool. A detailed illustration –
anchoring of the side wall of the pool shell. Finish concreting up to the final height of the base concrete.
The height of the base concrete means its level in relation to the final landscaping around the pool shell,
so the height of the pavement or other final finish must be allowed for. During concreting, keep checking
the verticality and flatness of the walls and the shape (diagonals) of the pool.

1. Measures against Damage to the External Shell of the Pool.
Protect the pool shell around the perimeter against damage in a suitable manner, e.g. by applying a mirelon
tape, which protects the outer shell from damage by sharp objects and, at the same time, allows for dilatation.
Measure the height at which you will need the cover of the skimmer; its height can be adjusted manually by
extending it by up to 30 mm.
2. Gravel Underlay for Final Surface
Lay the aggregate (grain size 16 to 32mm) under the concrete plate on which the final surface around the
pool will be created.The visible upper part must be connected to the final surface by means of commonly
available permanently elastic sealants (ideally, the filled space between the final surface and the pool outer
wall is at least 5mm).
3. Making the Base Plate for the Final Surface
The height of the base plate depends on the height of the final surface (paving, stone carpet,…) and its levelling.
This plate should be made of monolithic concrete reinforced with rebar mesh (100 x 100 x 6mm). The height
of the base plate depends on the height of the type of paving that is chosen. Make the final base plate for the
paving; any irregularities can be levelled with a trowel. At this stage, it is also necessary to install the anchoring
elements (plastic footing) for the pool steps and the junction boxes for pool lights, if these are included in
the contract for work. The final surface for the enclosure, if any, must be firmly connected to the concrete
base. Paving is the most suitable option of the final surface. It must be firmly attached to the concrete base
(must not be supported by sand or gravel). Other suitable types of final layers include all solid materials that
are designated for the purpose, to be firmly attached to the concrete base. The visible (final) upper part must
be connected by means of commonly available permanently elastic sealants to the outer coat of the pool
(ideally, the filled space between the final surface and the pool outer wall is at least 5 mm).
