Kindly suggest best economic way to control seepage in heavy black soils, having clay content more than 60 percent and soil depth more than 2 meter in semi arid region of India.
What type of black soils? Are we controlling seepage in dam walls? We run an alluvial gold mining operation where water is scarce and line the bottom of our dams with fine iron rich soils such as goethite and hematite rich soils to avoid seepage. It forms a clay like material that acts as a barrier. Clay is king im not ebtirely sire what you wish to achieve. However 60% clay ahould be pretty good
