Abstract: The need to have a concrete with low absorption is very important in irrigation canals to keep water inside it without losses due to permeability, since, concrete is a porous material, therefore, this study include the effect of integral waterproofing admixture type ADM-10-1110 which is a liquid chemical polymer with organic compounds and using it individually with concrete and also using it with polymer modified concrete that contains styrene butadiene rubber polymers. This admixture make concrete with very low absorption and having a high mechanical properties. The ordinary mixes with 475 kg cement for each 1 m3 concrete show high increment in compressive and flexural strength by using Integral Waterproofing Admixture (IWA) and less absorption, absorption decreased from 7.8-1.3%, compressive strength increased from 36.9-47.4 MPa and flexural strength increased from 2.7-7.24 MPa for polymer modified concrete, water absorption for it was very less, it decreased from 4.8% for reference mix of PMC to only 0.18% when adding 2.5% IWA by weight of cement.
