Expansive clay or expansive soil is a clay or soil that is prone to large volume changes (swelling and shrinking) that are directly related to changes in water content. The engineering properties of such soils are high compressibility, low bearing capacity and low shearing strength. In this study the expansive clay is treated with rubber latex modified coir in different percentages to study the effect on soil. Natural fibers are used to determine the bearing capacity and shear strength of treated soil. They are biodegradable and hence will not create environmental problems. To increase the durability of coir added to soil natural extract- rubber latex was used to preserve it. The clay content found in the soil was 65.65%, so it is considered as clayey soil and silt content was 34.35%. From the study, the coir treated with rubber latex gives increase in strength up to 2% inclusion to the soil.
