Bentech Bentonite gets its high performance clay from a natural volcanic mine formed millions of years ago in Jilin Province, North East China.


The mine itself is situated over 250 meters underground, and has thus far heeded more than 20 million tonnes of pure bentonite clay for production. 


We researched it. We tested it. We found that Bentech Bentonite is not only a high quality product, manufactured under rigorous quality control systems, but that since its inception in 1982, over 3 million m2 of product has been installed across the world. 


Bentech Bentonite is Codemark Approved - the first of its kind in New Zealand. We are thrilled to introduce a truly competitive, tried and tested bentonite product to the New Zealand market.
