The main objective of this thesis was to carry out an experimental in situ study to waterproof the Gochirca-Tayabamba canal based on lime-sand clay and improve its conduction efficiency. The development of the project was carried out in three stages, the first, consisted in calculating the flow of the channel by means of direct measurement (bucket method) being this one of 4.61 L/s, to find the loss of flow of the channel by infiltration being this one of 1.41 L/s (30.56 % of total flow), to calculate the efficiency of hydraulic conduction obtaining a result of 69.41 % and to determine the different proportions of the mortar made with clay, sand and lime, which had the following proportions respectively: Sample 1 (70%, 20%, 10%), sample 2 (60%, 30%, 10%), sample 3 (50%, 25%, 25%). In the second stage to determine the mechanical properties of the clay and sand, laboratory tests were carried out, obtaining their classification respectively according to SUCS low plasticity clay (CL) and poorly graded sand (SP), and according to the AASHTO classification, clay material A4 and granular material of group A-1-b; and finally, the infiltration test was carried out, the process of which began with the excavation in situ of 03 calicatas with a depth and diameter of 0.30 m each, then coated with the mortar under study with a thickness of 0.03 m, water was added to observe and note twice a day its decline, the evaluation period lasted 8 weeks (56 days) and at the end the results of the test were analyzed and it was determined which is the most efficient dosage against infiltration, being this sample No. 1 with a dosage: 7:2:1. The third and last stage consisted of performing the infiltration test in a 2.8 m section of channel lined with the best mortar dosage, first the initial flow (4.07 L/s) and final flow (3.93 L/s) of the section without lining was measured, then proceeded to measure the initial flow (4.05 L/s) and final (4.04 L/s) of the lined section to determine the level of infiltration of the flow, being this of 0.01 L/s; and finally it was compared with the results obtained from the measurements made in the unlined channel, thus finding an efficiency of 99.8 %. It was concluded that it is possible to increase the water conduction efficiency of a waterproofing channel by using mortar with proportions: 70% clay, 20% sand and 10% lime, due to the fact that clay is a material with a low level of permeability, sand helps to improve consistency and workability, and lime is a natural binder being able to join different materials and improving their adherence.
