Oregonite® (Sobranite)
Oregonite®, also known as Sobranite, is a pure sodium bentonite clay without additives, available from PROMAFORSOVEMA's permanent stock. Thanks to its remarkable swelling capacity (2 to 7 times its volume), it effectively isolates the aquifer from polluted surface water. Oregonite® is used before and in addition to a cement plug to ensure optimal borehole sealing.
