IGLU’® for the new Paul Biya Stadium

Paul Biya Stadium (even known as Olembe Stadium) is a sport facility in Yaoundé, in Cameroon, for whose construction, some innovative materials and solutions, such as Iglu’® by Daliform Group, were chosen.
With its 60,000 seats, Paul Biya Stadium aims to become the new landmark of the Cameroonian capital.
Iglu’® was chosen and used to create ramps, steps, structural fillings and height compensations.
The quality of the used recycled material, its particular geometric conformation, the thickness, the product’s dimension and the processing techniques make Iglu’®, by Daliform Group, the excellence product on the worldwide market.
Numerous national and international awards have been received over the years which testify to the rich and appreciated contribution that Iglu’® has managed to give to the world of construction.

Fight against the capillary rising moisture with IGLU’®

Iglu’® is the leading market product, created and patented for the realization of sanitary spaces, ventilated cavities, under-floor cavities, ventilated floors and roofs during the construction and renovation of civil and industrial buildings.

The ventilated cavity, realized with Iglu’®, is an effective solution to the problem of rising moisture on the flooring, because the under-floor cavity’s ventilation placed under the floor, dries it naturally. Thanks to the cavity, the building can breathe, by constantly eliminating the moisture: this technique was born already at the time of the ancient Romans.
To guarantee an appropriate ventilation, both in renovation and in new buildings, the connection of the ventilated cavity to the outside with simple pipes is necessary.
As a matter of fact, to obtain a natural «chimney effect» is necessary to position the inlet holes on the northern side at a height just off the ground and the outlet holes on the southern side at a higher point (preferably up to the roof), being careful to connect the various rooms of the foundation grid together so that the entire under-floor cavity is connected. The ducts positioned inside the wall with southern exposure will heat up, causing an upward motion intaking air from the under-floor cavity.

A ventilated under-floor cavity created with Iglu’® represents an effective, quick and economic solution that makes it possible to send humidity and dangerous Radon gas to the atmosphere, which is beneficial to our health.

Daliform Group, ligereza estructural para el nuevo Campus Bocconi

The recent expansion of Bocconi University Campus in Milan occupies, in the south of the historic campus, the zone “Ex Centrale del Latte”, a site that covers an area of 36.000 square meters.

The new university campus, headquarter of the SDA Bocconi School of Management, includes a series of buildings surrounded by a green area that serves as connection with the rest of the campus and the city. University residences, classrooms and rooms for teaching and research stand alongside a sport and leisure centre – with an Olympic-size swimming pool – open to public.
The typical sinuous volumes of SANAA are connected by covered paths that cross the park; there are no main façades, but a flow of semi-transparent surfaces allowing a glimpse of the activities taking place within the university spaces.

All the buildings open onto the green internal courtyards, which, thanks to the fully glazed façades, allow the interiors to benefit from a consistent supply of natural light.
The request of the architectural design was to create slabs without down stand beam and with smooth soffit.

From the structural point of view it was required a type of slab that would permit to obtain a light, but at the same time resistant, structure with low deformability, given the presence of flat and curved glass in the external façades.

Daliform Group, that has always stood out for the ability to create innovative products for buildings, recommended then its product U-Boot® Beton: a disposable formwork in recycled polypropylene, studied to create lightened bidirectional slabs in reinforced concrete, cast on site, with perfectly smooth soffit, even exposed.
With the integration of U-Boot® Beton system by Daliform Group on the project, it was possible to create structures that perfectly responded to all the requested performances; the lightened system is flexible and fits into the curvilinear plans with irregular layout of the vertical bearing elements.

The use of U-Boot® Beton permits to obtain several advantages on the entire structure (even in the case of variants): less use of steel in the slabs on average 15%, pillars and foundation on average 20%; less concrete on the slabs (on average 25%) but even on columns and foundations, even if modest; reduction of the seismic and gravitational actions connected to reduced building weight; slimmer pillars and foundations; lower costs related to excavation for foundations; more freedom on the layout, even irregular, of the pillars for the benefit of the architectural quality of the project; reduction of work and overhead transfer of the formworks; advantages in on-site logistics.

The Daliform Group technical office is available to provide to designers specific technical information, feasibility studies and assistance in the executive design. (tecnico@daliform.com – Tel. +39 0422 2083)

Effective ventilation for the “Nuvola” by Fuksas

The “Nuvola” by Fuksas, in the Eur district in Rome, is a work of great architectural impact for which innovative materials and solutions have been chosen and applied, including Iglu’® by Daliform Group.

The “Nuvola” by Fuksas, in the Eur district in Rome, has been the main centre of the G20 summit recently held in Rome.
The project signed by the well-known Roman architect is a jewel of architecture and engineering, which combines the capital’s historical and Baroque core with the district’s rationalist approach, through innovative solutions, an environmentally compatible approach and technologically advanced materials.
It is a work of great architectural impact for which innovative materials and solutions have been chosen and applied, including Iglu’® by Daliform Group.

The Iglu’® disposable formwork is a revolutionary system for creating cavities in general, crawl spaces and ventilated floors.
The formworks, made of recycled and recyclable plastic material, thanks to their easy interlocking installation, allow the quick creation of a self-supporting pedestrian platform, above which a layer of concrete is cast. The cavity thus obtained will have a spherical shape and, with the connections outside the building, will allow a maximum ventilation. In addition to creating a «sanitary vacuum» with an adequate vapor barrier for the floor, Iglu’® promotes the disposal of natural radioactive gases emanating from the ground, in particular radon gas.
The peculiar characteristics of Iglu’® are rationality, ease of processing and above all the speed and simplicity of installation. The created cavity also allows the insertion of technological networks without drowning them in the base screed of the flooring, ensuring the possibility of inspection and integration with additional systems that may be necessary over time.

Daliform Group continues its research and technological development activities according to the guidelines that have determined its success: simplicity, rationality, economy. This study and experimentation activity has created a series of new components that complete the product range, increasing its application possibilities.

Tanques para recolección y dispersión de agua de lluvia

Atlantis System by Daliform Group is the ideal solution to create tanks for rainwater collection and/or dispersion.

The tanks for rainwater collection and dispersion are installations suitable to collect rainfall peaks, allowing sewage and water treatment plants to work at the most constant regime with unquestionable economic benefits and operating efficiency, even in peak load situationsz

Atlantis System by Daliform Group is the ideal solution to create tanks for rainwater collection and/or dispersion.
Atlantis permits the creation of a reinforced concrete tank, cast directly on site, with various dimensions in plan and height up to 300 cm to maximize the volume. The structure obtained thanks to Atlantis System is made by a slab on grade, perimeter walls and a slab supported by vertical supports. The structure guarantees a high resistance to permanent and imposed loads.

The tank created with Atlantis System by Daliform Group can be laid underground to obtain a green area above it, or made it suitable for the transit of even heavy vehicles.
The created tank is vehicle accessible and can be created under squares, roads and car parks, both commercial and industrial. The tank aims to mitigate the effect “flood” caused by exceptional weather conditions.
This way, the draining capacity, which the cement had previously taken away, is returned to the soil without any visual or environmental impact.

Protecting the road pavement from trees’ roots

Trees’ roots often represent a problem for sidewalks, bike paths and roads. By creating a cavity with the Atlantis System, below the road pavement, the roots are prevented from breaking the overlying pavement.

Urban greenery has become an indispensable aspect for improving the quality of life and making cities more vibrant and colourful.
Often, however, the green is simply inserted to the side of roads, on sidewalks or bicycle paths. Maintenance work must be carried out regularly as the tree roots raise the pavement until breaking through and then going back underground, following a horizontal path.

The Atlantis System, born to create ventilated cavities, can easily solve these problems because, thanks to the cavity created by itself, allows roots to grow in their natural way, without damaging the overlaying pavement.
This System by Daliform Group, avoids the constipation of the terrain for the creation of the pavement and allows the realization of a cavity that facilitates gas exchange and tree stability, preventing the lifting of the soil.

There are many advantages for the community: no maintenance costs for the sidewalk/bike path; greater “satisfaction” for residents who will not complain about damaged pavements; fewer accidents involving the elderly or people with limited motor skills; the public green area can be designed to support any vehicular traffic.

There are many advantages for the greenery: creation of a greater volume for the expansion of the roots with a consequent increase of the tree stability; greater drainage of rainwater; integrable with irrigation systems or with tanks for the reuse of rainwater; no lifting of the soil as the roots, finding the right oxygenation and the right compaction, do not need to emerge.

Improving the seismic response of buildings thanks to the lightened slabs with U-Boot® Beton

When you erect new buildings, the structures have to be designed to resist to seismic stress, as prescribed by the anti-seismic standards.

Daliform Group, Company that has always been outstanding for its capacity to create new innovative products, has developed seismically efficient building solutions: putting some hollow elements in recycled Polypropylene, called U-Boot® Beton, in horizontal structures to optimize the distribution of the concrete masses, thus reducing the quantity used.

In this way, you obtain the additional advantage of saving steel for the reinforcement: with the same thickness compared to a monolithic slab, with U-Boot® Beton you get a weight reduction of up to 40%. This has a positive effect on the rest of the structure thanks to the reduction of seismic and gravitational actions.

All this leads to larger structural meshes, absence of emerging beams, more flexible spaces and more adaptable environments over time.

U-Boot® Beton replaces the obsolete and problematic traditional lightening systems in polystyrene and brick, ensuring superior structural performances, high quality standards of the slab and a perfect and homogeneous intrados finish, allowing to satisfy even the architectural needs.

U-Boot® Beton guarantees excellent performances even when used for structures to be built in the most demanding seismic areas.

Post-tensioned and lightened slabs with U-Boot® Beton for the multi-level parking in Reims

To improve the slabs’ performances, minimizing labour costs and raw materials used, the lightening system U-Boot® Beton has been included on the project for the realization of lightened slabs coupled with a post-tension system.

The multi-level car park “Republique” in Reims, finished in October 2020 and built of reinforced concrete, has a capacity of 745 parks reachable via ramps that allow access to vehicles up to the roof.
In order to optimize the inner spaces of circulation and to add two rows of car parks, the project had to be realized with 16 m large spans. The designers decided to use lightened slabs with U-Boot® Beton in reinforced concrete coupled with a post-tension system. The presence of the two technologies made it possible to achieve the goal and create the slabs without building pillars in the central areas and thus maintain the project spans of 16 m.

Daliform Group company supplied the elements U-Boot® Beton, that installed as disposable formworks directly on the horizontal shuttering, create the voids inside the slab.
Due to the lay in rows, they create ribs all along the slab length, where sheathed and greased prestressing strands and passive steel are laid. As the consequence, the prestressing steel benefits from the maximum possible lever arm for 40 cm of slab thickness, while the slab weight is considerably lightened.

Once again, the use of U-Boot® Beton has proven to be the ideal technological solution for the realization of a work that needs great spans and great architectural freedom, which allows to use the inner spaces on the best way. In addition, the reduction of the overall load of the structure has allowed an important optimization of the vertical bearing structures and foundation structures.
