Expansive soils prevail over a large area of Sudan and have caused significant damage to irrigation systems, water lines, sewer lines, buildings, roads and other structures located on these soils. Current estimates of damage exceed five million Sudanses pounds (six million U.S. dollars) annually. Based on soil properties, soil surveys, and damage reports, over one-third of Sudan's 2.6 million square kilometer area may have potentially expansive soils. Based on soil data collected from over 30 sites, free swell as high as 125 per cent (mean of 68 per cent) and swelling pressure as high as 630 kn/sq M (mean of 210 kn/sq M) can be expected for potentially expansive soils.
