ArmaLynk® geogrid Environmental Product Declaration receives EPD Hub certification

Reinforced Earth’s geogrid geosynthetic, ArmaLynk® has received certification from EPD Hub for its Environmental Product Declaration (EPD). This certification provides detailed information on the environmental impact of the product throughout its lifecycle, meeting key international environmental standards.

What is ArmaLynk®?

A geosynthetic, ArmaLynk® is an ultra high strength geogrid for soil reinforcement and ground stabilisation applications.

The geogrid is made from high tenacity polyester yarns. These yarns are extruded, coated to form polymeric strips encased in a Polyethylene sheath, and then welded together to create a stable and robust geogrid structure.

This versatile geogrid can be used in various applications, including:

  • Embankments over soft and very soft soils: Prevents slips and enhances stability.
  • Reinforced embankments over areas prone to subsidence: Reduces impact and minimises surface deformation.
  • Piled embankments with basal reinforcement: Provides support to structures like bridges, piers and tanks, creating a resilient infrastructure.
  • Piggyback landfill expansions: Efficiently raises dykes over existing landfills and increases landfill capacity.
  • Lagoon closures: Facilitates sludge lagoon remediation on soft ground, aiding in land reclamation and redevelopment.
  • Access roads and load-bearing platforms: Improves soil stiffness, lateral restraint, and controls settlement, particularly beneficial for heavy load movements.

ArmaLynk® offers a comprehensive solution for various engineering challenges, promoting sustainability and resilience in infrastructure projects. Contact us to find our more.

Why is EPD certification important?

The Environmental Product Declaration (EPD), is a standardised and internationally recognised document that provides transparent and verified information about the environmental impact of a product throughout its entire lifecycle, from raw material extraction to disposal, outlining the meeting international standards such as EN 15804+A2:2019, ISO 14025, and ISO 21930.

Receiving certification for an Environmental Product Declaration demonstrates a commitment to environmental stewardship, transparency, and sustainability. It signifies that the product has undergone rigorous assessment and meets international standards for environmental performance reporting.

In addition to EPD certification, ArmaLynk® is CE certified for soil reinforcement applications and is currently undergoing certification by the British Board of Agreement (BBA).

Further detail on the applications for Reinforced Earth’s ArmaLynk® geogrid:

Embankments on soft soils

ArmaLynk® is used as layered soil reinforcement for building embankments on poor sub-soils for improving stability. ArmaLynk® helps in reducing the construction time and increases the global performance of the project. Embankment foundations reinforced with ArmaLynk® are able to withstand high static and dynamic loads.

Embankments over subsidence and void bridging

ArmaLynk® is used in reinforced fill layers to bridge any potential voids and cavities formed in the underlying soil and thus avoiding sinkhole formation for any new structures, embankments or roads built over of such formations. Areas having historical sites with geological fissures and formations prone to subsidence (for example mining sites) may require soil reinforcement measures with ArmaLynk®.

Load Transfer Platforms and piled embankments

ArmaLynk® is used in the transition layer for distribution and transfer of loads to rigid inclusions such as stone columns or piles in soft foundations. This composite solution optimises settlement control and the load-bearing performance of the rigid inclusions.

Ground stabilisation

ArmaLynk® is used as basal reinforcement in layers or as a flexible mattress for ground improvement works for airport runways, railways, access roads, working platforms, hardstands, heavy duty port pavements and similar applications.

Reinforced Steep Slopes and walls

ArmaLynk® performs as a high-performance soil reinforcing elements for building mechanically stabilised reinforced steep slopes and walls.

Landfill expansions

ArmaLynk® can be used effectively in combination with other Reinforced Earth products for landfill expansions to solve the ever growing problem of waste disposal, especially for raising dykes over existing landfills or increasing the capacity of existing landfills.

Land reclamation

ArmaLynk®, used in combination with other Reinforced Earth ground stabilisation techniques facilitates all types of sustainable land reclamation and redevelopment, for example sludge lagoon remediation on soft soils.
