ABSTRACT: It is becoming a great challenge for the civil engineers to design suitable foundation for the
structures on marine clay. The paper presents an innovative design for construction of foundation on marine clay
soils. In this process geofoam, Expanded Polystyrene (EPS) is placed below foundation. Geofoam properties like
lightweight, high strength give best option as fill for poor quality of soil. The various combinations of sizes and
density of geofoam under footing, for reduction of settlement are studied. A numerical finite element analysis
program, PLAXIS, is used to simulate the problem. The decrease in settlement under the footing and the increase in
bearing stresses were compared to those without EPS. Load settlement relationship was studied. Results concluded
that use of Geofoam (EPS) decreases the settlement and increases the footing load. EPS thickness appeared to be an
important factor in improving footing behaviour on marine clay, compared with density of geofoam (EPS)
