Clay is considered one of the most important raw materials in cement industry. It is the most common rich source
of silica and alumina. During the quarrying process a few months later, a new feature of water accumulation
appeared on the quarry floor and many water pools were formed during excavation process. In order to detect
the source and extension of the ground-water seepage, geoelectrical resistivity technique in the form of vertical
electrical soundings was applied. Fifteen vertical electrical soundings with AB/2 from 1 to 150m have been
executed.
Geoelectrical resistivity measurements are applied in Helwan clay quarry to understand the source of the
groundwater accumulated recently on the floor of quarry. The results indicate the passage of groundwater from
the adjacent areas through channel ways formed as a result of the excavation process. All over the measured
area, there are some sand lenses intercalated with clays & during the excavation process, some channels formed
and the groundwater started to percolate through these channels forming many water pools along the quarry
floor
