Soil stabilization is a technique that uses other materials to improve the durability of soil by increasing its strength and resistance to water. Cowdung was used as a soil stabilizer in a soil stabilization investigation for the construction of adobe bricks. The investigation consisted of mixing cowdung with sandy clay soil in the cowdung/soil ratio of 0:1, 1:6, 1:5, 1:4, 1:3, 1:2, and 1:1. The adobe bricks were evaluated for compressive strength, permeability, erosion and cracking. The results showed that the 1:4 ratio had the highest compressive strength and the highest resistance to erosion. The highest resistance to water penetration after a period of three hours was shown by the cowdung/soil ratio of 1:5, and there was minimum cracking in all the treatments.
