Protect and repair the environment around your structure
In the United States, the Environmental Protection Agency (EPA) defines green building as "the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle from siting to design, construction, operation, maintenance, renovation and deconstruction."
Sometimes projects or facilities have unexpected or unintended results, doing more harm than good to surrounding areas. A variety of environmental construction products and processes can be used to mitigate damage to the environment and ensure strong construction for the future.
Geosynthetics can be used to protect soils, create foundation structures, and reduce a surrounding areas’ exposure to harmful particles found in contaminated soils. In marine settings, filtration mattresses can be an economical and environmentally-friendly option. And as site availability for landfills decrease and compliance requirements increase, budgets are tested to their limits. There is a mounting need to get the most out of (and into) existing landfills.
Some cities are buildling expensive seawalls and water pumps to fight the increased flooding and land loss brought on by climate change. Instead of hardened shorelines, like bulkheads, which can create unanticipated damage, living shoreline techniques provide an alternative that uses natural materials combined with engineered materials to slow down erosion.
Tensar's family of innovative composite marine structure solutions are made of geogrid and geotextile materials designed to be integrated with available fill and/or native vegetation. These marine structures allow for the formation of reefs to cushion the impact of waves on the shore, which in turn reduces overall shoreline loss.
Capping & Filtration
Flexible and resilient, Tensar's marine mattresses conform to land contours and site formations, resisting scour far better than rigid systems. And because they feature Tensar geogrids, they resist all naturally occurring forms of chemical, biological and environmental degradation – from salt water to industrial runoff to contaminated sediments. They’re often specified for aggressive site conditions where other types of materials would rapidly deteriorate.
Tensar’s marine mattresses have been deployed as part of a modular reactive capping system for the remediation of non-aqueous phase liquids (NAPL) contaminated sediments. Tensar’s mattresses can also be configured to encapsulate alternative fill materials, such as sand or carbon, in order to provide site specific remediation solutions for a broad range of in situ capping applications.
Tensar’s marine mattresses have also been specified for the construction of submerged foundations. Installation-friendly and extremely adaptable, they simplify construction and increase the support over bottom soils prone to settlement or scour.
Tensar’s grid composite system is specially developed for use beneath riprap and armor stone. By combining Tensar geogrids with geotextiles, grid composites provide an improved foundation and filtration layer for a broad range of riprap, rubble-mound structures and similar installations.
Tensar’s marine cells are used to construct high-strength, composite earth fills in adverse conditions – including confined, structural-quality fills built below the water level or with weak fill materials (a geotextile liner placed within the cells enables the use of fine-grained fill materials).
Our landfill capacity improvement systems make use of engineered berms to create a reconfiguration of a waste containment facility. These berms maximize disposal capacity while meeting all regulatory requirements and enhancing the overall revenue potential of the site.
