This research focus on improving engineering properties of laterite soil using Portland cement type 1 and rubber latex. Laterite soil was mixed with cement, water and rubber latex in the ratio of 5 : 2 : 1 by weight to prepare the improved specimen. Strength of the specimen was further tested by mixing water in the rubber latex in different proportions of 5%, 7.5%, 10% and 12.5%. The strength test was performed on 28th day for dry cured specimen that consists of compressive strength, flexural strength, tensile strength and water absorption. The results show that soil-cement, 7.5% rubber latex solution and water when mixed in the proportion of 5 : 2 : 1 gives the best performance. Average strengths on 28th day were 84 ksc of compressive strength, 19 ksc of tensile strength, 8.75 ksc of flexural strength and 6.23% of average water absorption. Thus, improvement of soil-cement with 7.5% of rubber latex and water solution gives the best results. This research applied rubber latex, soil cement to construct drought relieving water pond. A pond was constructed on the field with farmer’s participation using; the pond was tested for water seepage in the field and showed satisfactory results. Farmers can take advantage of water saved in the pool during the drought season.
