Anchored Earth Retention
A joint ADSC-DFI committee of industry-wide professionals who design, construct and supply equipment for temporary and permanent support of retaining structures using ground anchor techniques, such as tiebacks and soil nails. Through the use of education, training, seminars, research, specifications, and other means, this committee works with public and private owners, contractors and suppliers to increase the use, understanding, quality and economy of earth retention structures that use ground anchor techniques.
