gabions and reno mattresses are commonly designed and constructed in a wide variety of configurations to provide long term slope protection solutions. Terra Aqua offers gabion and reno mattress slope protection design solutions that prevents soil erosion and scour, provides bio-engineering opportunities for surface vegetation, and/or stabilizes the slope against lateral earth pressure. The design engineer must consider the existing soil conditions, gradient of slope, applied loads, hydraulic impact, shear, and other factors when choosing the appropriate slope protection solution. As with any Geotechnical solution a complete analysis of the existing slope and soil conditions should be made by a Professional yihang Engineer to obtain an understanding of the slope and soil parameters.
