Abstract

Indonesia is a country that located at the confluence of three major plates, making it prone to ground movements disaster. PT. Astra Otoparts (limited) is a company that set up branch office in semarang and located in areas that experiencing local mass movement (local). This happens because there is a slip plane, has a lithology that consits of soil embankment and clay that has low value of cohesion and poor consistency. Therefore, it should be made ground investigation to determine how much strength and physical condition of the soil, so as to know the proper methods to overcome these problems. The method used is grouting, but before doing grouting, grouting experiments needs to be done, ie grouting test. Grouting test is a method that used to determine the effectiveness of the grouting to be done. Based on the analysis that has been done, we can know that the grouting method can increase the carrying capacity of the land on the foundation of the building. After the measurement, the value of N-spt increase from 2 up to 19 in the CH-2 and in CH-1 up to 21 in depth 4.50m to 5.00m. In the depth 9.50m to 10.00m at each check bore hole the value of N-spt from the previous 16 - 21 up to more than 60 in each hole. In the depth 14.50m to 15.00m at each check bore hole the value of N-spt increased from the previous 48 - 49 up to more than 60. Efforts to increase the value of SPT with grouting method on soil that has a low bearing capacity at PT. Astra Otoparts successfully performed, so that the process of building PT. Astra Otoparts can proceed. Key word : mass movement, grouting, soil strength
