In January 2023, SAB S.p.A. contributed to the Tallinn’s Environmental House project in Estonia by providing a custom drainage solution: the SABdrain polypropylene (PP) channel system with steel edges, D400 load class, designed to ensure efficient stormwater management in a complex comprising three buildings.
Commissioned by the Estonian Ministry of the Environment, the project aimed to improve management efficiency, reduce administrative costs, and promote strong environmental sustainability. In this context, selecting a durable, low-maintenance, and cost-effective drainage solution proved to be crucial.
Technical Solution and Specifications
The channels were installed along the building perimeter, precisely beneath the eaves, at the point where rainwater flows off the roof. This strategic positioning allows the system to efficiently collect and direct water, preventing pooling and structural damage.
The chosen SABdrain model included:
- Polypropylene (PP) channel body with steel edges, D400 load class, internal dimensions 500×500 mm, and cast iron grating.
- Grid drainage capacity of 1070 cm³, optimizing water flow.
- Low-roughness PP material, ensuring effective self-cleaning and reduced maintenance.
This solution fully met the project requirements, guaranteeing efficient rainwater drainage. Its ease of maintenance and long-lasting durability also helped minimize long-term operational costs.
Economic Sustainability and Functionality
A key factor in the success of this solution was the integrated design, which includes immediate connection to drainage pipes. The male/female joint system ensures watertight sealing between channels, preventing leaks and unnecessary maintenance.
Moreover, the entire SABdrain range, including this system, is UNI EN 1433 certified, guaranteeing the highest quality and safety standards.
Transport and Logistics: Sustainable Efficiency
Another important advantage of the SABdrain system is its lightweight design, which simplified transportation and installation on site. This not only reduced logistics costs, but also contributed to lowering the environmental impact of material transportation.
Conclusion
The adoption of the SABdrain D400 system for the Tallinn’s Environmental House project represented a significant step toward achieving both environmental goals and economic efficiency. SAB’s innovative and sustainable solution has played a key role in the success of a project that promotes sustainability and innovation in urban infrastructure development.
