Erfenis Dam serving irrigation purposes is 140 ft high and 1605 ft long; placing of 136.000 cu yd of mortar intrusion concrete into structure; 26,000 cu yd of normal reinforced concrete was also used; intrusion method differs from grouting as it involves placing cement-sand-water mixture, not by pressure, but only by gravity; use of double-drum Colcrete mixers; construction plant, formwork, materials and intrusion operations described.
