Expansive soils are highly problematic soils with an innate capacity for swelling and shrinkage corresponding to changes in moisture regime. Because of the alternate swelling and shrinkage undergone by these soils in rainy seasons and summers, many lightly loaded civil engineering structures like residential buildings and pavements are severely cracked. It is, therefore, necessary to devise a suitable foundation for these soils. Granular pile- anchors (GPAs) are a recent foundation technique that proved quite effective in controlling the volumetric changes in expansive soils and...
