Abstract

The settlement of shallow foundations on granular soils is a critical factor in their design, and the rise of the water table due to seasonal or hydrological changes can lead to additional settlements, affecting the structural integrity of the asset. This paper investigates the use of expanding geopolymer resin injections as a cost-effective alternative solution to reduce foundation settlement due to a rising water table through numerical modeling. The study utilizes the PLAXIS software to run a series of virtual experiments, assessing the effect of geopolymer resin injections on foundation settlement with different rising water tables. The study found that geopolymer resin injections can reduce the impact of rising water tables on the settlement of shallow foundations and it is most effective when applied within the influence zone of the foundation.
