Abstract:
Several remedial techniques were developed world-over to combat the damages caused by expansive soils and have been practiced with varying degrees of success. All the techniques have their own limitations in terms of their technicality and effectiveness and researchers have been trying to develop new techniques or modify the existing techniques. In order to understand the relative performance of the popular foundation practices in vogue and few recently proposed techniques in swelling soils, an attempt is made to cast footings in the field with different traditional techniques like sand cushion, CNS layer, Under-reamed piles, lime piles and the recently proposed tension piles, anchored granular micropiles, calcium chloride and calcium chloride – sodium silicate stabilization. Seasonal cyclic footing movements were monitored continuously over 4 years for different techniques.
