PVT´s commitment to sustainability
Our R&D team is constantly working on the creation of new products, always in line with sustainability. We have our own laboratory in which the most significant production parameters are tested daily. In addition, independent and accredited laboratories such as Applus+ or Eptisa Engineering Services, as well as prestigious European universities such as the University of Cantabria, University of Navarra or University of Twente (UT), periodically certify that our products achieve their maximum performance. We believe that quality is not a question of minimums but of maximums and this is demonstrated by our products: ecoGranic and ecoDraining.
ecoGranic® is a technology developed and patented by PVT, implemented in a high resistance concrete prefabricated. In addition to compelling its architectonical and esthetical function, it actively contributes to the elimination of atmospheric pollutants.
This technology is very efficient in the elimination of nitrogen oxides (NOx), volatile organic compounds (VOCs) and particulate matter (PM). This prefabricated product is environmentally friendly. It is produced with recycled materials, among others, especially from construction and industrial sectors.
ecoDraining® is a modular paving with high draining capacity that also incorporates ecoGranic® decontamination technology. It consists of two layers: an upper layer that gives it exceptional aesthetic properties and prevents the slab from clogging, and a lower layer that gives it good mechanical properties.
The use of ecoDraining on the surface (pedestrian or different vehicle transits) avoiding accumulations of water, puddles, etc., are considered urban green infrastructures with a multifunctional character : mitigators of the urban heat island effect that causes the waterproofing of the cities, sonorreductive, anti-slip and decontaminating pavements (NOx degradation, class 3 norm UNE127197/1) as well as being made with recycled material.
Water Sensitive Urban Design (WSUD)
New problems in the sustainable development of cities
The traditional growth and development of cities involves the covering of their ground with impermeable materials such as asphalt and concrete, which significantly alters the natural water cycles.
The lack of natural infiltration of rainwater into the ground produces important disturbances in ecosystems, as well as the reduction of aquifers.
On the other hand, as experts warn, climate change means an increase in the propensity, intensity and frequency of extreme weather events, such as torrential rains, which cause flooding and damage to river ecosystems and more rapid soil erosion.
Of particular concern is the fact that current infrastructures for the management of polluted water are affected in these cases, with the result that some of this water is forced to be discharged into rivers without prior treatment.
Likewise, the lack of humidity on the surface of the urban soil limits the natural cooling produced by water evaporation, something that, currently, is only associated with parks and green areas.In addition, the materials with which the city is normally paved accumulate heat during the day, becoming sources of emission during the night, a phenomenon known as “heat island”, increasing the temperature of the air and forcing greater energy consumption for cooling.
Heat Island Effect
The lack of moisture on the surface of urban land limits the natural cooling produced by the evaporation of water, something that is only associated with parks and green areas.
In addition, the materials with which the city is normally paved accumulate heat during the day, becoming emitters at night, a phenomenon known as “heat island”, increasing the air temperature and forcing greater energy consumption in cooling.
Water Sensitive Urban Design (WSUD)
Sustainable drainage is the ideal alternative for the adaptation of cities to climate change, not only to mitigate the effect of floods, but also to properly manage the quantity and quality of the urban runoff water.
Sustainable Urban Drainage Systems (SUDS) enable water infiltration near the origin and prevents the formation of surface runoff, constituting an advanced technical solution for the correct management of rainwater. In addition to flood mitigation and the prevention of water pollution, SUDS improve urban landscapes, optimizing their value and minimizing the economic costs of rainwater management.
