- Abstract
The high groundwater table and the placement of the basement below the groundwater level give rise to several issues, one of which is groundwater seepage. The accumulation of groundwater seepage on the basement floor surface leads to discomfort for the building users, as observed in Building X, located in the Central Semarang Area, Semarang City. A further investigation is required utilizing groundwater seepage modeling on the basement floor to analyze the causes of problems. The methods employed include analytical and numerical approaches facilitated by Geostudio SEEP/W software. The modeling encompasses a basement floor length of 94 meters and ground water level (GWL) elevation ranging from 0 cm to 400 cm relative to the basement floor surface, with 50 cm intervals. The analysis results reveal that higher ground water level elevations concerning the basement surface correspond to more significant seepage discharge values, velocity, and uplift values. Moreover, as the distance from the point on the basement floor increases, seepage discharge values, velocity, and uplift decrease. At the GWL elevation of 300 cm from the basement floor, the observed field seepage discharge value of 44.04 L/day exceeds the modeled seepage discharge value of 43.70 L/day by 0.771%. Meanwhile, the highest modeled seepage discharge value is 44.814 L/day, and the maximum uplift value is 3.034 kN/m2, occurring when the GWL elevation matches the ground surface level, likely during the rainy season. The uplift value is deemed safe for the floor plate; thus, addressing the groundwater seepage issue in the basement involves injecting polyurethane material into the basement floor cracks and applying a finishing layer using polyurethane rubber coating.
