The AquaRockBag® system is the forefront of modern engineering for coastal, marine, intertidal and inland waters. AquaRockBag® is an environmentally innocuous, high-performance net filled with graded rock which is used in erosion control, scour protection and landscape (re-) modelling. Due to its unique characteristics, it is the optimal alternative to the aforementioned conventional methods for four major reasons: 1. High interstitial spaces absorb water energy while simultaneously providing habitat for flora and fauna through accretion of sediments, 2. Due to its flexibility, AquaRockBag® adapts well to uneven surfaces which eliminates the need for ground preparation works (to a large extent), 3. AquaRockBag® is easily placed in deeper water environments, 4. It is the optimal base for softer soil bioengineering methods to be used at and above average water level thus providing a natural solution that blends in perfectly with its surrounding. AquaRockBag® works best under water and can be combined with softer soil bio-engineering Solutions at and above average water level to achieve a natural solution blending in perfectly with its surroundings.
