The patented U-Boot® Beton allows to build lightweight
structural concrete slabs and rafts, by creating internal
voids placed in zones where the shear demand is low.
This technology is the ideal solution for creating slabs
with large spans and great load-bearing capacity, which
allow designers to be more creative and free in the use
of space, as the slabs are thinner, totally flat and may
require a slimmer supporting structure, without the need
of ribs and drop panels around the columns.
This is achieved by embedding the U-Boot® Beton
formwork in the concrete, resulting in the formation of a
hollow core plate, with continuous lower and upper slabs,
connected by orthogonal ribs, interconnected with each
other.
The U-Boot® Beton voided flat slabs offer an efficient
and sustainable solution to architects, engineers and
contractors, thanks to the reduction of concrete and steel
in the slabs, columns and foundations, as well as the
reduction of the embodied carbon of the entire building,
compared to a conventional concrete structure.
Due to its modularity, simple handling and toughness,
U-Boot® Beton reduces construction times and associated
costs, and improves the technical performance of
buildings.

Real advantages
We are incorrectly led to estimate the advantage of a slab lightened with U-Boot® Beton limiting it to a mere comparison between
savings in concrete and the cost of the formwork on the level of the slabs only. In this way however, as the analysis is immediate
and intuitive, it does not account for the various economic, practical and operational advantages provided with U-Boot® Beton
for the entire structure: less use of iron in the slabs, pillars and foundation up to a total of 15% (also in the case of variants); less
concrete is used not only for the slabs but also for the columns and foundations; there are antiseismic advantages connected to
reduced building weight; slimmer pillars and foundations, lower costs related to excavation for foundations; the arrangement, also
irregularly if needed, of the pillars to reflect the architectural freedom of the structure. Reduction of work and overhead transfer of
the formworks; advantages in on-site logistics.

FLEXIBLE
Span up to 20 m. No beams between pillars. Reduction in the
number of pillars. Can be used together with prefabs. Does
not require handling and/or hoisting equipment. Possibility of
single direction structures thanks to the bridge accessory.
LIGHT - THIN - BIDIRECTIONAL
Reduction of weight up to 40%. Reduced deformations
(maximum loss of stiffness- 15%). Reduction of the foundation
load. Reduction of of columns section or their number.
ECONOMIC
Lower concrete cost with an equal thickness.
Lower steel cost.
Savings in useful height on each level as there are no emerging
beams.
Possibility to gain floors at the same building height (towers)
and building volume.
Quick and easy to implement.
Also indicated for the top-down technique.
Possibility of large span at equal load or high load bearing
capacity at an equal span.
Economical and easy to transport, handle and store, also
outdoors.
The soffit has a flat surface that is ready to finish and does not
require a false ceiling for aesthetic purposes.
If a false ceiling, is required it can be created faster.
EARTHQUAKE PROOF
Lower seismic mass. Fewer dimensional limitations for the
elements. Double slab, upper and lower.
OPEN SPACES
Larger spaces. Greater architectural freedom. Simplified
changes to the purpose of use.
FIRE RESISTANT
Considerable fire resistance certified REI 180 with a concrete
cover of only 3 cm.
IMPROVED ACOUSTIC BEHAVIOUR
Thanks to the increased stiffness of the lower and upper slabs,
acoustic transmittancy is decreased.

Applications
U-Boot® Beton is used in all applications that require a structural plate
together with the need to use less concrete and therefore for a lighter
structure.
U-Boot® Beton is the ideal solution for creating slabs with a large span
and/or great load-bearing capacity: it is particularly suited for structures
that require considerable open spaces, such as executive, commercial
and industrial buildings as well as public, civil and residential structures.
It makes it possible to more irregularly distribute the pillars, as beams do
not need to be created.
In the case of yards that are difficult to access or restructuring work,
U-Boot® Beton, due to its stackability, modularity, lightness and
manoeuvrability, can be used to make horizontal structures without the
help of handling and hoisting equipment.
With U-Boot® Beton also foundation rafters can be created with a larger
thickness with a reduced amount of concrete.

Vimar’s industrial building
U-Boot® Beton allows even the reinforcement
of existing slabs through the execution of a selfsupporting voided slab without the use of the feet
superimposed on the existing floor and casted on the
extrados of the latter, which will act as a formwork.
In this way you will have the possibility to reduce to
a minimum the increase of the self-weight and the
consequent increase of the loads transmitted to the
existing structures.
With this technique you will carry out work for the
construction of the new slab without having to interrupt
the activities in the lower floors, thanks to the extreme
lightness of the system.

Among the various foundation types, rafts are one of the most well known.
They are used above all in ground conditions with little bearing capacity,
or with poor quality soil, large thicknesses must be used which increases
the construction cost.
Thanks to the use of U-Boot® Beton lightened rafts can be created with
the same performance but at a considerably lower cost.

Beams in the slab thickness - The spacer joint
The U-Boot® Beton lightened plate slab has a perpendicular beam gridwork of the same
thickness as the slab that transfers all stresses directly to the pillars around which it will
suffice to leave a full zone of variable dimensions based on the shearing forces. Beam
dimensioning and their perfect implementation on site depends on the orderly and precise
layout of the lightening elements during installation but especially during casting.
Correct positioning of the U-Boot® Beton is guaranteed by an effective rigid spacer joint
with graduated scale with which the desired width of the beams is quickly determined. The
joint fits into the top of the formwork inside notches housing the fixing elements.
Thanks to this system, the connection of the formworks is simple and quick because it is not
hindered by the beam reinforcements.
The rigid interconnection ensures perfect geometric compliance with the design as well as
with the bearing capacity of the formworks when casting under the pressure of the concrete,
the weight of the operators and equipment.
Soffit slab with high thickness
In order to determine the thickness of the soffit slab, elevator feet of variable height, 11 to 20
cm, are available in addition to 0 to 10 cm feet: these accessories are to be grafted on site
on the existing ones.

the floatation of the formworks: an initial layer will be cast to fill
a thickness equal to the height of the elevator foot. Casting will
continue for this first portion of the slab until the concrete starts to

Application examples: rafts
Among the various foundation types, rafts are one of the most well known.
They are used above all in ground conditions with little bearing capacity,
or with poor quality soil, large thicknesses must be used which increases
the construction cost.
Thanks to the use of U-Boot® Beton lightened rafts can be created with
the same performance but at a considerably lower cost.
Once drown in the concrete casting, U-Boot® Beton forms the structure
just like two full slabs, with a variable thickness, connected by a
perpendicular beam gridwork to form a bidirectional static honeycomb
plate.
For this concrete bed, the distribution of weights due to hight inertia is
rationalised in order to permit maximum stiffness and lightness for the
structure with a minimum amount of concrete, which makes it possible
to eliminate, where possible, the foundation piles.

U-Boot® Beton: excellence
The quality of the used mixture, the innovative shape, the thicknesses and dimensions of the product, the fire safety and strict working
techniques make it a product of excellence.
U-Boot® Beton, is not subject to deformations, either during or after the casting, either due to the weight of the concrete or the dynamic
effect connected to the work operations: it is able to support before casting the workers and fresh concrete, the pressure created during
the compression and vibration of the casting, the weight of people, reinforconcretes and equipment guaranteeing conditions of safety,
and lack of deformations. Furthermore, the safety of the lateral spacer guarantees its perfect positioning and respect of the geometry of
the beams under the pressure of the concrete.
Numerous national and international Product and System Certifications have been received that prove not only product quality, but also
the validity of the constructive solutions and the applications in the building industry
All of this, together with the advantages mentioned below, make U-Boot® Beton the product of reference for operators and professionals.
U-Boot® Beton: advantages compared to other systems for lightened structures
Further advantages deriving from U-Boot® Beton
compared to other systems for lightened structures
(polystyrene or hollow block) are the dimensions, handling
( just think of transferring it overhead onto the slabs being
built) and outdoor storage both on the ground and at
heights. One pallet of U-Boot® Beton H 20 is sufficient for
a slab of about 300 m2.
The hollow blocks are heavy, bulky, frangible and cannot
be stacked.
Polystyrene is bulky, cannot be stacked, can absorb water
causing phenomena of efflorescence; it is particularly
fragile leaving those annoying balls that, statically charged,
stick to everything (especially to the reinforcements) and
are very hard to get rid of.
U-Boot® Beton or polystyrene formwork?
With reference to lightened slabs, the Italian Ministerial
Decree of 16.02.2007 to enclosure D.5.1 establishes
that: “In the case of polystyrene formworks, or formworks
in similar materials, there must be appropriate vents
for the overpressures”. Even prior to this, the UNI 9502
standard - article 7.2.2 - established that: “In the case of
elements incorporating materials that when subject to high
temperatures turn to gas, there must be appropriate vents
facing the side exposed to fire to ensure that the bearing
capacity is not compromised by explosions”.
Therefore, using polystyrene slabs cast on site requires the
extra expense of fitting vents in the cavity to counteract
the excessive pressure of gas that is sublimated by the
formwork. However, in the event of a fire there would still
be the problem of toxic gas escaping into the environment
(styrene).
U-Boot® Beton is made of polypropylene, it is not toxic even if burnt.
Moreover, the slab will not explode due to the escaping of over
pressurised gas from the feet (4 feet for each formwork) that act as
safety valves. Tests run at the CSI laboratory have demonstrated
that with a cement cover of 3 cm the structure created with U-Boot®
Beton is class REI 180.

This certificate is very important for U-Boot® Beton because it demonstrates: the lack
of dangerous substances in its composition (even if recycled materials are used); the
lack of emissivity of toxic substances during the various phases of the product's life and
operating cycle, which benefits the health of the intermediate users (production and
installation personnel) as well as final users (people living in the building) as well as the
environment in general.

U-BOOT® BETON
Supply of lightening formwork U-Boot® Beton and its accessories, for the execution of a reinforced concrete slab, with a bidirectional
capacity, to be casted on suitable horizontal formwork (or on a prefabricated slab).
Total slab thickness is ______ cm lightened in compliance with the design, with recycled plastic elements such as U-Boot® Beton of
the Daliform Group Company, truncated-pyramid in shape with a crossed semi-cylindrical notch at the top to put reinforcement bars or
installations to be integrated in the casting. U-Boot® Beton has got plan dimensions equal to 52 x 52 cm and height equal to H ______
cm, with the four semi-circular notched corners at the base of which the conic elevator foot is created, in integral way, facing down, with
a height equal to H ______ cm, basing on the scaffolding to form the thickness of the intrados suitably reinforced with bidirectional
mesh of reinforcing bars in steel type B450C, with diameter and spacing adapted to the design stresses.
The supply includes positioning of the U-Boot® Beton modules with rigid spacer joints to form a link and thus create the perpendicular
ribs between the formworks according to the predefined thickness and ensure the perfect geometry and bearing capacity upon
casting, to be placed at the top of them inside the notches.
The supply and casting of the concrete (minimum resistance class equivalent to C25/30, consistency class Slump S4 or S5 and
diameter of the aggregates such to avoid “segregation” phenomena) is also included. The lower slab must be made, in a first phase,
by casting the concrete and vibrating it until it covers the entire U-Boot® Beton feet (max 4 cm above them in case of Double type
lightening). In a second phase, the completion casting will continue as soon as the first layer has lost fluidity (in this second phase a
class of concrete consistency other than the previous one is allowed).
The U-Boot® Beton modules, produced in ALAPLEN® CV30, must be safe to walk on and certified with a resistance characteristic
of 150 kg in the weakest point on an 8 x 8 cm footprint; they must not release any polluting substances and must have a Certificate
of Compliance with the environmental compatibility criteria (CCA) and be produced by a company using an Integrated Management
System (ISO 9001, ISO 14001, ISO 45001, SA 8000).
The final design of the voided slabs must have graphs and calculations provided by the Company supplying the U-Boot® Beton, which
must exhibit the product certificate approved by an EOTA member Body (European Organisation for Technical Approvals).
The Manufacturer must provide: the Technical and Safety Data Sheet of the product and as well as that of the granule used ALAPLEN®
CV30; a Certificate of acoustic behaviour that shows the raw minimum value of the sound insulation of the bare floor (Rw) equal to 56
dB, and a value of the noise level of footing of the bare floor (Ln,w) maximum of 82 dB verified on a lightened slab type of thickness equal
to 26 cm (5 + 16 + 5), issued by certified Third Parties.
With reference to fire regulations, the Manufacturer must provide fire behaviour test, issued by an accredited Body, which demonstrates
for a voided slab of 25 cm thickness (5 + 16 + 4) a fire resistance REI 180 with a design moment of at least 4880 daNm and minimum
concrete cover of 3 cm, and which also demonstrates that the behaviour of the U-Boot® Beton feet is similar to that of overpressure
relief valves, and therefore it is not necessary to provide suitable vents for overpressure (as, on the contrary, it is necessary for
lightening in polystyrene or similar materials). Moreover the Manufacturer will have to provide a detailed study, conducted by an EOTA
member accredited Body, of the fire behaviour of a lightened slab with elements in recycled plastic, executed on scaled samples from
which the isothermal temperature propagation curves inside the slab can be deduced.
In addition, the manufacturer shall provide, on request, appropriate certifications relating experimental test that proving the bidirectional resistant mechanism of the system, namely its actual behaviour as a slab, and appropriate certifications relating to tests of
slab-column node, in order to provide the system’s ability to perform, in a seismic zone, its secondary system function supported to a
primary system of ductile bracings.
The cost for the creation of holes with the dimensions and sections foreseen by the architectural drawings is also included, the price also
includes and covers all costs for providing the finished work in a workmanlike manner; it does not include the supply and positioning
of the horizontal formwork that supports the slab and accessories, the steel reinforcements, which will be entered separately.
