1)non-chemaical additives
2)good air&water permeability
3)durable
4)aging-resistance
5)resistant to corrosion

Not contain chemical additive, without heat treatment, it is environmental protection building material. It can replace the traditional engineering materials and construction method, construction safer, and helps to environmental protection, can be more effective, economical and lasting to solve engineering construction of basic problems.Have good mechanical properties, good permeability, and resistance to corrosion, anti-agingWith isolation, inverted filter, drainage, protection, solid, strengthen, and other functions. Can adapt the bump grass-roots, can resist construction force damage, creep decrescent, long-term load can still keep the original function. Overall good continuity, light weight, construction is convenient.
