Green architecture against the social degradation. A trend which is spreading day by day not only like a concept of the residential and private building’s furniture, but also to redevelop some degraded suburbs’ areas with innovative solutions from the technological point of view.
This is the case of a social housing complex in the city of Boulogne Billancourt (France), once inhabited by the workers of the Citröen, now incorporated by Paris itself and subject to massive redevelopment by great architects such as Jean Nouvel, Renzo Piano, Herzong & De Meuron to name a few. What was once a popular area is now turning into one of the most modern and chic districts of the “Ville Lumière”. The intervention concerned two buildings built in the 1960s, in a state of decay and inhabited by socially difficult people, to whom it was decided to make the living space more pleasant and livable: the separation surface between the two buildings, to cover the garages, it was then transformed into a green area.
The main problem that arises in the realization of these compositions is to create the different levels without excessively burdening the load-bearing structures. Of course, the existing structure had limited possibilities to be further loaded and therefore the use of Iglu’® Green Roof and the Atlantis System was the ideal solution to the problem. In fact, thanks to the Iglu’® Green Roof and the Atlantis System it was possible to create spaces at different levels quickly, easily and absolutely economically.
Daliform Group has always been concerned with providing innovative solutions in the construction field that are oriented towards environmental protection and energy saving. The Iglu’® and Atlantis systems, based on disposable formworks in 100% recycled polypropylene, initially created to create ventilated crawl spaces and cavities, over time have found increasingly widespread use in other fields of application such as: recovery and collection of rainwater, cycle paths and greenhouses, anti-root applications, roofs and hanging gardens, geothermal energy and heat recovery.

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.

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.

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.

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.
