Drainage board features more significant drainage function and filtration effect and is more affordable than traditional stone ceramsites.
It is used in landscape works, construction works, traffic works, municipal works and renovation works.

Drainage board effectively solves the problem that traditional landscaping methods(such as using pebbles,
shells ceramisites as filter materials) cannot store water,prevent the plant root system from damaging the surface, 
preserve and insulate heat and the load is large. It has prominent features, namely water storage,drainage, 
breath ability, thermal insulation and root puncture resistance. usage in a large area can achieve such effects as water saving,
energy saving and noise isolation and effectively mitigate the city's thermal effect.
