Building with Recycled Plastic Products: Lightweight Slabs with U-Bahn® Beton for Sustainable Construction

In contemporary construction, the quest for innovative and sustainable solutions is increasingly paramount. Within this context, lightweight slabs with U-Bahn® Beton emerge as a high-performance and environmentally conscious choice.
Crafted from recycled plastic, U-Bahn® Beton modular formwork exemplifies the principles of the circular economy.
The advantages of this technology extend beyond environmental benefits, offering tangible improvements in construction efficiency.

Why Choose U-Bahn® Beton for One-Way Lightweight Floor Slabs?

As a lightweight and stackable void former, U-Bahn® Beton provides exceptional design flexibility. Unlike brick piñatas and polystyrene formers, it facilitates the creation of cavities for the passage of cables and installations.

PERFORMANCE ADVANTAGES

Maximum Versatility: U-Bahn® Beton is ideal for the production of precast slabs, significantly reducing construction time and labour costs.
High Precision and Uniformity: The U-Bahn® Beton void former ensures perfect concrete rib geometry, enhancing structural performance.
Improved Site Cleanliness: Its compact and modular design minimises waste and debris on site, promoting a cleaner and safer working environment.
Enhanced Seismic Performance: The presence of a double reinforced concrete shell imparts greater rigidity and seismic resistance to U-Bahn® Beton slabs, making them ideal for areas with high seismic risk.

APPLICATIONS

U-Bahn® Beton is the optimal solution for lightweight one-way slabs in a diverse range of buildings, including residential, commercial, office, industrial structures, and public buildings such as schools and hospitals. It is particularly suited for applications that require one-way slabs and floors where minimizing structural loads is essential.
This system not only reduces the need for concrete and steel but also significantly lowers the building’s embodied carbon footprint.

A notable application is in underground construction using the «top-down» technique. Unlike traditional open-air construction that progresses from the bottom up, this method involves constructing load-bearing slabs from the top down, alternating slab construction with the excavation of lower levels.
This technique is often employed in the development of underground car parks in historic city centres, where the presence of adjacent buildings and the necessity for rapid road system restoration pose significant constraints.

Atlantis System: An Innovative Solution for Effective Rainwater Management

Continuous cementation and increasing settlement densities, although necessary for human development, are causing significant changes in surface and groundwater regimes. Additionally, climate change and rising temperatures are altering weather patterns. The most obvious effects of this climatic trend are more intense and concentrated rainfall, followed by extended periods of drought. These extreme weather phenomena significantly increase the likelihood of flooding due to severe and sudden deluges.

Soil sealing prevents rainwater from being absorbed into the ground, shortening runoff time and causing water to reach receiving bodies much more abruptly. This leads to several problems:

  • Reduction in Water Reserves: Less rainwater is absorbed, lowering aquifers and risking their depletion.
  • Sewer Overload: A sudden increase in the volume of water can jeopardize system functionality, resulting in flooding and associated social costs.
  • Water Quality: As water flows through urban areas, it becomes increasingly polluted, leading to greater wastage of drinking water.
  • Flood Risk: On a larger scale, river basins can collapse, causing flooding with potentially tragic consequences.

Stormwater storage tank

In a context where hydraulic invariance is a standard in new construction, the Atlantis System offers a practical and effective solution for creating water harvesting and lamination tanks. Utilizing the Atlantis System, it is possible to construct rainwater harvesting tanks, dispersion tanks, and water recycling greenhouses. These reinforced concrete tanks, consisting of a bottom slab, perimeter walls, and a top slab supported by columns, are engineered to support a range of loads, including pedestrian walkways, landscaped areas, and car parks.

These tanks can be installed under forecourts, roads, and commercial or industrial car parks to mitigate the effects of flooding caused by exceptional meteorological events. This approach restores the drainage capacity of the ground lost to concrete, without any visual or environmental impact.

Legislation on water protection emphasizes the need for constructing catchment and dispersion basins to prevent flooding and highlights the growing importance of sustainable land transformation. Public authorities can benefit significantly from constructing rainwater dispersion basins. This not only recharges rather than depletes the groundwater table but also eliminates the need to oversize sewer networks as cities expand. Additionally, a comprehensive cost-benefit analysis for an area – be it a municipality, province, or river basin – can facilitate the implementation of a complete hydro-geological rehabilitation plan, thereby significantly reducing the risk of flooding.

DALIFORM GROUP — Creation and production of plastic products for the construction industry

The Daliform Group Company in Gorgo al Monticano (TV), 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, originally made to create ventilated crawl spaces and cavities, over time have found more and more uses in other fields of application, like: rainwater collection tanks, bike paths, green houses, anti-root applications, green roofs, geothermic and heat recovery.
During the last years these products have had an important success on architects and landscapers with their use on green roofs in urban areas.
Nowadays urban spaces must be revised: the citizen who lives in large cities like Milan, Paris, London, Tokyo and New York feels the need for greenery, shuns asphalt and concrete.
Not surprisingly, and increasingly, both in the interventions of new urbanization and urban redevelopment, the best architects of the moment foresee that the ground level above the basements are used as greenery with trees, plants, bushes, lawns and, of course, equipped with play areas for children. These areas are increasingly thought of as a real simulation of natural environments, with slopes, hills and changes in altitude.
The most important problem during the realization of these compositions is to create different levels without excessively burdening the load-bearing structures.
Thanks to the Iglu® and Atlantis System products, it is possible to create spaces at different levels quickly, easily and absolutely economically by configuring the space in a flexible and dynamic way: a simple concrete completion casting, reinforced with a very light electro-welded mesh, will provide you with a support that, covered with a layer of a few tens of cm of fill soil, will transform what was previously a cemented space into a real green urban area.
Among the many references of Daliform Group products, one stands out in particular in the context of a social housing complex’s redevelopment in the city of Boulogne Billancourt (Paris), subject to massive redevelopment by great architects such as Jean Nouvel, Renzo Piano, Herzong & De Meuron to name a few.
Daliform Group is the point of reference in the construction industry for those who design, distribute and construct.
Is an innovative company that spreads the culture of excellence by offering the best products and best solutions for the environments in which we live, work and enjoy ourselves, that aspires to help everyone working in construction to do it better, more efficiently and more attractively, improving the quality of life.

Iglu’® Green Roof by Daliform Group for green roofs in the cities. New gardens for the city’s life.

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.

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.
