The inherent flexibility and porous nature of gabion products address the design concerns of headwalls which must properly dissipate the energy of water flow, withstand or relieve soil and hydrostatic pressures, and in areas prone to such seasonal changes, withstand the effects of frost action acting upon the soil. Because headwalls or wingwalls improve the flow of water into and out of conduits, provide anchoring support for the pipe and prevent dislodging under excessive pressures, control erosion and scour resulting from high water velocities and turbulences and to prevent adjacent soil from sloughing into the waterway opening. Headwalls are necessitated by limited space and poor soil conditions.
Gabion structures can be built with speed and economy in all circumstances and are particularly suitable for landslide control in mountainous countries and in areas with persistently bad ground conditions. Where ground is liable to subside, the capacity of gabion to deform makes them preferable to a concrete wall which would crack and collapse. In addition to the distinct structural advantages over concrete and other non-porous gravity wall structures, the potential to vegetate a standard gabion box or wire faced wall offers unique landscaping potential as well.
