Uboot Beton per solai alleggeriti

VOIDED SLABS FOR EARTHQUAKE RESISTANCE

U-Boot® Beton allows for a reduction in mass of up to 30% compared to a solid concrete slab, resulting in an overall reduction in load of between 10% and 20%.

The devastating force of an earthquake, causing damage to buildings and people, is an unpredictable natural event that can challenge our safety and stability. Therefore, it is important to proactively address the challenge of earthquakes through a combination of preparedness, scientific understanding and preventive action.

THE REGULATORY FRAMEWORK

One of the objectives of civil engineering is to ensure maximum resistance of structures to the effects of earthquakes, protecting human life and minimising structural damage to buildings. In this sense, all the most advanced technical standards that are the reference for designers, such as Eurocode 8 EN 1998-1, refer to two primary performance principles that must be satisfied: the protection of human life in the case of seismic events of infrequent intensity and the limitation of damage to structures in the case of seismic events that may occur with some frequency.

International standards for the design of horizontal slabs allow this type of deck to be considered not only as horizontally rigid, but also as a structure capable of dissipating seismic energy.
As a result of numerous experimental campaigns, it appears that the behaviour of slabs subjected to horizontal actions also allows these systems to be studied as primary in terms of seismic resistance.
Similar results are reported in the technical notebook developed by the Politecnico di Milano entitled “Reinforced concrete voided slabs subjected to gravity and seismic actions”- D.Coronelli, L. Martinelli, F. Foti – 2016. In the near future there will be a real revolution in the seismic analysis of buildings, which will give further impetus to the use of slabs in general and, consequently, to lightweight slabs.

A VOID FORMER MADE OF RECYCLED PLASTIC

During a seismic event, the force acting on the structural system is directly proportional to the mass of the building and the acceleration of the underlying ground. It is therefore obvious that if you want to reduce the actions involved, you can act on the mass of the building.

With a view to increasing the sustainability of buildings, the Daliform Group has developed a technological, practical and effective solution for creating voided biaxial slabs using U-Boot® Beton, a recycled plastic void former certified to the Second Life Plastic (PSV) standard by IPPR, the Institute for the Promotion of Recycled Plastics.

Although the use of slabs is not the only way to design a seismically resistant building, the choice of a two-way slab becomes the most usual when it is necessary, from an architectural point of view, to create structures with no regularity in the plan.

PROJECT FOCUS

A concrete example of the result of the above points is the new university campus in Milan, home to the SDA Bocconi School of Management.
An urban redevelopment project on the site of the former “Centrale del Latte”, designed by architects Kazuyo Sejima and Ryue Nishizawa of the Japanese studio Sanaa, covering an area of 36,000 square metres.

The decision to use U-Boot® Beton in this project enabled the creation of a sinuous and curved floor plan, deviating from typical designs and perfectly meeting high-performance standards. This approach resulted in a more slender load-bearing structure, even vertically. Compared to a solid slab of the same thickness, using U-Boot® Beton allows for a mass reduction of up to 30%, leading to an overall load reduction of between 10% and 20%.

Radon, an invisible health hazard

Radon is a gas of natural origin that is odourless, colourless and tasteless, and therefore cannot be perceived by our senses. According to the World Health Organisation (WHO), prolonged exposure to this gas can cause serious health damage, increasing the risk of developing lung cancer.

The European Union has urged Italy to prepare a plan ‘against Radon gas’ applicable by 2031, which envisages the measurement of concentration levels in the territory of the gas and the subsequent evaluation of measures to intervene. Since the early 1990s, Daliform Group Srl has been developing and patenting its products based on the regulations of the Friuli Venezia Giulia Region, precisely to counteract the rise of Radon gas in new and renovated residential buildings.

Building an aerated under-floor cavity with the Iglù® disposable formwork is an effective solution to counteract the rise of Radon. Indeed, the system, exploits the principle of natural ventilation to allow air to circulate: by connecting the under-floor cavity to the outside using special pipes, a flow of air is created which facilitates the dispersion of Radon and humidity from the cavity below the ground floor.

These are the main advantages of choosing an air cavity made with Iglù®:

Effectiveness
It significantly reduces the concentration of Radon in rooms.

Health
It improves indoor air quality and eliminates excess humidity, preventing mould and condensation.

Durability
Durable and long-lasting system.

Sustainability
Made of recycled plastic, it contributes to environmental protection.

Iglu' Barrier Daliform Group per pareti

Iglu’® Barrier: the protection system for retaining walls

Superior performance and durability, Iglu’® Barrier is a recycled plastic panel created to protect the waterproof layer in the walls against the ground.

Thanks to its technical specifications, it guarantees excellent compressive strength by creating a ventilated cavity and avoids contact between the ground and the waterproofing of the retaining wall.

Walls against the ground are exposed to humidity due to capillary action, to which can be added the possible condensation of humid air as a consequence of inadequate thermal insulation.
This situation can lead to the formation of mould, unpleasant odours and above all compromise the durability of the structure.
Iglù® Barrier finds application in various areas, protecting against water infiltration and rising damp.
Ideal for underground areas such as garages, cellars and other underground areas.

Among the several benefits, some peculiar aspects might be highlighted as follows:
Comfort
The resulting air chamber that is created protects from temperature changes, reducing the “cold wall” effect. Thus, heat loss may be reduced, contributing to energy savings.
Superior protection and resistance
Made of high-strength materials, Iglu’® Barrier acts as a barrier for foundations against penetrating damp, condensation and other atmospheric agents, preserving the structural integrity of buildings.
Sustainability
Daliform Group, who plays an active role in sustainability issues, collaborates with professionals and institutions to spread environmentally friendly construction practices. Iglu’® Barrier is one of them, providing projects with environmentally friendly perimeter protection.
Ease of installation
The modular and intuitive design allows for quick and simple installation, reducing construction time and costs, as well as increased safety in the excavation covering process due to excellent compressive strength.
Versatile applications
Iglu’® Barrier adapts to different foundation configurations and soil types, making it ideal for both residential and commercial buildings.

IGLU' Green Roof

GREEN ROOF – Much more than a trend: a great way to help the environment

The projects that integrate green spaces in buildings are steadily increasing, thanks also to the archistars who have been able to turn the spotlight on solutions that combine aesthetics and sustainability.
Green roofs play the leading role for projects around the world with the aim of bringing nature back to the city. This could be pursued, for example, by transforming roofs/rooftops into green spaces that can lend a distinctive character to buildings, while contributing to the fight against progressive cementification.

Green roofing is a valuable solution to the traditional system and it is now a solution adopted by many designers, both for aesthetic reasons and especially for the improvement of building performance. They are linked to the theme of Smart Cities, which embraces concepts intertwined with a new way of seeing the urban reality, based on citizens’ well-being and energy efficiency. Green roofs are permeable spaces that can counteract pollution and promote countless environmental benefits, contributing to energy savings. In some cases, the latter is as much as 10% compared to a building with a traditional roofing system.

These gardens, placed on top of a wide variety of building types, are divided into two types: extensive or intensive – depending on the thickness of the substrate. The extensive green roof is suitable for stratigraphies with reduced thickness, it is generally not usable and requires little maintenance throughout the year. The intensive, on the other hand, is the most traditional solution and allows a great variety of plants, shrubs, and trees – thanks to a stratigraphy with greater thickness.
IGLU’® GREEN ROOF, produced by Daliform Group and made of recycled plastic material, is the solution for creating a green roof that can guarantee:

  • high capacity to retain and store water, facilitating more gradual drainage in case of heavy rainfall and avoiding the disappearance of vegetation due to a lack or excess of water.
  • environmental sustainability through the improvement of the macro- and micro-climate and of air quality.
  • sound insulation, mitigating the action of acoustic waves and reducing propagation to the underlying environments by some decibels, resulting in improved comfort inside the building.
  • thermal insulation, with less heat loss in winter and natural cooling in summer.

Easy Park® Griglia di protezione per prati già formati

Awareness and sustainability in the Daliform Group lawn protection grids

During these years, the problem of plastic pollution of our planet has reached an unprecedented urgency. More and more we realize the importance of being able to recycle it, giving it new life, thus avoiding further contamination of the environment and the living organisms that populate it.
Even in the building sector, recycling is became one of the key point on the new construction.
For this reason, Daliform Group, which has always been committed to the creation of recycled plastic products, is pleased to highlight the numerous advantages that can be acquired by using its lawn protection grids for the creation of driveway and pedestrian flooring (with lawn or gravel finishing) or for the protection of already formed lawns.
These grids are made totally or partially of recycled plastic and it is precisely the particular compound that allows to achieve an excellent quality-price ratio.
Among the numerous products of the Daliform Group GREEN division, in addition to the flagship product PRATOPRATICO®, we can highlight E.C.O. by Pratopratico® and Green Park, capable of offering excellent quality-price ratio and, at the same time, excellent technical performance.
Another interesting product is Easy Park®, very easy to pose on the existing lawn, it could be used also in case of temporary floors for events, parking and landing areas for helicopters.
Using the Daliform Group lawn protection grids, among others, the following advantages can be obtained: no waste production (recycled and recyclable material), respect for the hydrogeological balance of the soil, better aesthetic performance of the environment, resistance to atmospheric agents.
So why recycle plastic and reuse it? For Daliform Group, the answer is clear: “Because operating with the utmost respect for the environment, with a view to awareness and sustainability, is an ethical gesture from which our generation can no longer escape”.

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.
