GIS APPLICATION IN THE IMPROVEMENT OF BEARING CAPACITY OF SANDY SOIL BY CEMENT GROUTING

This study evaluated the impact of cement grout as a stabilizing agent for the improvement of the bearing capacity of sandy soil by grouting and the use of Geographic Information system (GIS) to provide the necessary geographical information. This study was achieved by conducting the collection of soil sample in Iguoshodin community at a depth of 1.5m and the samples were taken to the University of Benin soil laboratory centre to conduct the necessary laboratory tests. These tests were natural moisture content test, specific gravity test, sieve analysis test, cone penetrometer test and standard proctor compaction test, all in accordance with the British Standard BS 1377: Part 2: 1990. The Geographic Information System (GIS) was used to carry out queries of the attributes of the soil samples in reference to the available soil standards. As a result, the time it takes to obtain the data is greatly reduced because it is constantly available
