The use of drainage geocomposites is booming in applications such as roads and other infrastructures, landfills, heap leach pads, buildings, etc. They offer performance and consistency to fulfill a function which is one of the most critical in a structure: most of failures in construction are indeed directly or indirectly connected to a drainage issue. However, what makes them truly attractive compared to traditional drainage layers is the significant savings they typically generate, on both dollar figures and carbon footprint.
This webinar will present the key properties of drainage geosynthetics, as well as what needs to be addressed while designing a structure including a geosynthetic drainage product. The presentation will include an overview of the main properties of these products, how they are tested, as well as the main design methodologies used around the world, published by GRI, ASTM and ISO. Issues such as flow capacity, transmissivity, durability, creep, biological clogging, geotextile intrusion, ‘allowable’ versus ‘required’ flow rate will be discussed. A quick overview of how drainage geo-composites interact with the structure, such as veneer stability and filtration performance, will also be presented. The webinar will end with a Question and Answer session.
