AquaRockBags®: Resilient protection that provides habitats for diverse range of flora and fauna.
The AquaRockBag® is highly flexible, works far better with natural processes than other revetments, provides ecological benefits, can be vegetated over relatively short time scales and helps reduce currents in areas that are erosion-prone.
Filling & Installation Benefits
- The onshore filling process makes it quicker and safer.
- AquaRockBags® are placed using a crane and a quick hitch.
- Due to flexible nature of the AquaRockBag®, the bags adapt to the surface resulting in no/minimal preparation.
- Lifting eye makes it easy to move the filled AquaRockBag®.
→ Rapid filling and installation on site with big savings on labour costs
- Optimal alternative to large rock armor or concrete. AquaRockBags® are absorptive rather than reflective due to the high interstitial spaces between the rocks. As such, water energy is absorbed, resulting in natural processes being retained and minimising the impacts downstream or around the AquaRockBag® revetment.
- Stone sizing and grading within the AquaRockBag® has been developed to provide a balance between the structural interlock needed to provide a robust revetment and the optimum grading for ecosystem development and diverse biotic community habitat. AquaRockBag® encourages fine accretion of sediment to enable vegetation establishment providing habitat for insects, molluscs and other invertebrates, which in turn supports fish and water bird populations.
- UV stabilised nets are abrasion resistant and do not suffer from corrosion.
- AquaRockBags® can be used in conjunction with Soil Bioengineering techniques as a hybrid solution to create genuine ecological enhancements within the revetment design.
Resilient protection whilst also providing habitats
During the Yearls Weir River Derwent project, our partner company Salix River & Wetland Services Ltd. collected a sample of invertebrates that settled within and around the AquaRockBags® during the installation phase. Examples found in research from Swansea University include: Phyllodoce maculate, Capitella capitata, Scoloplos armiger, Melita palmate, Carcinus meanus, Idotha pelagica.
