It is known that deep-raft foundations below a high groundwater table are associated with uplift-pressure problems. Conventional solutions, such as increased dead weight, tension piles, or ground anchors, are costly, time consuming, and sometimes inefficient. A successful approach using a geosynthetic system to stabilize and relieve the hydrostatic uplift pressure within the impervious strata is presented. Filtration, clogging, transmissivity, and other properties of geosynthetics are specified to assure the dissipation of uplift pressure in the long run. The design concept was applied in practice to a multistory commercial complex. Two typical cases are introduced. Monitoring results are also covered. Based on the site experience, the installation of this system was found to be rapid, simple, and cost-effective.
