Gabion has penetrability. Stone space provide sufficient water area, reduce the hydrostatic pressure, no need special drainage and easy cracking concrete installation. Do storm protection works in big storm places, stone space exists pores, when waves hit the mesh mat,

the storm's effects are substantially resolved, pull of vacuum is damaged when storms is back, can effectively achieve the protective effect.
the pores in gabion cage and mat create conditions for water flow, is convenient to achieve the natural exchange between water and soil, create living environment for aquatic life and micro-organisms in the water, thus increase the water purification capacity, protect and improve water source and water quality. After artificial laying soil or natural soil deposits, filling material pore create conditions for green vegetation. Even if does not sow seeds, will grow plants naturally, achieve optimization, landscaping, improve and restore the ecological environment .
Using gabion mesh is economical in hydraulic engineering. Gabion system is formed by steel wire cage and filling material, lower cost than general building material. The filling will be ok , as long as it can resist wind and has certain strength. Generally the stones in project site can be used as filling. Sometimes even using some clean construction waste as filler, so cost is lower. Especially the poor conditions of local base, it can save a large proportion of total project cost of ground handling charges.
