Vertical Barriers

The purpose of a Vertical Barriers is to prevent the ingress of damp and water into subterranean structures such as basements, cellars, tunnels and earth shielded buildings

The vertical barriers involving the insertion of a HDPE geomembrane thickness of 2.0 – 2.5 mm. maintained in a trench filled with self-curing mud whose function is twofold:

• They ensure the stability of the walls during the excavation.
• They contribute to hardening, the formation of a layer composite natural / mud artificiale.Il self-curing is generally made up of a mixture of water, cement and bentonite. For inserzion of HDPE geomembrane are used in the excavation of a frame or a roller. The geomembrane is formed from HDPE panels connected together by mechanical joints type Interlock.

The Joint Interlock creates a maze filled with bentonite slurry, which ensures an average waterproof geomembrane of less than 10 ¯ 8 cm. / Sec.

Ventilated Facades

The external coatings of buildings, play an important role in contemporary architecture and qualification of the urban landscape, as well as play an important role in protection against the elements, in particular, the exterior surfaces of buildings, are subject to multiple stresses, like mechanical, chemical, thermal, humidity, associated with not only the quality of human activity, but also with air and therefore weather. These same surfaces, play an important role in the aesthetic impact of the construction and the materials used must be compatible with the requirements of environmental protection and sustainable development.

The system of ventilated facades, represents the most complete synthesis of the requirements to a wall in order to achieve the well-being within a building, in fact it carries out the primary function of protecting the building from weathering and in particular from infiltration of rainwater into the building structure, that is the main cause of degradation.

Thus spacing the cladding slabs from the wall, creating a ventilated cavity. that combines the action of an insulating layer applied to the wall structure, greatly improve the thermal efficiency of the building.

The construction system is characterized by a build in superimposed layers consisting of:

•     Insulation material
•     Metallic structure
•     Cladding elements

Among insulating coating creates a gap of air (chimney effect) that activates an effective natural ventilation, in particular by promoting the removal of warm and wet.
