EcoStrap HA sustainable reinforcements
Geoquest has introduced EcoStrap HA reinforcements to the Australian market, marking an advancement in environmentally sustainable construction. This innovative reinforcement solution enables the use of site-won materials as backfill for mechanically stabilised earth (MSE) walls, reducing both the carbon footprint and project costs.
The Diggers Rest Level Crossing Removal Project in Victoria is the first Australian infrastructure project to utilise EcoStrap HA reinforcements. The technology is designed and supplied by Geoquest to enhance sustainability by allowing recycled concrete and lime-stabilised soils to be used as select backfill—materials that traditionally present challenges due to their high pH levels.
EcoStrap HA consists of polyvinyl alcohol (PVA) tendons encased in a polyethylene sheath, making it particularly resilient in high pH environments. Additionally, its polymeric strips offer enhanced stiffness and greater resistance to elevated temperatures, ensuring long-term durability in demanding construction conditions.
Geoquest Australia supplies EcoStrap HA nationwide, supporting industry efforts to integrate more sustainable and cost-effective solutions into major infrastructure projects. For further information, contact Geoquest’s local teams.
Other geosynthetic reinforcement straps offered by Geoquest
Our geosynthetic reinforcements are selected based on the characteristics of the intended backfill to be used, load factors, required service life and other considerations, engineers select from our four main categories of geosynthetic soil reinforcing strips:
> GeoStrap™
Coated polyester (PET) strips without high-adherence edges, best for low pH backfill
> HA GeoStrap™
Coated polyester (PET) strips with high-adherence edges, best for low pH backfill
> EcoStrap™
Coated polyvinyl alcohol (PVA) strips without high-adherence edges, best for high pH backfill
> HA EcoStrap™
Coated polyvinyl alcohol (PVA) strips with high-adherence edges, best for high pH backfill
