The Sika-1 Liquid additive is an integral waterproofing agent that, according to the manufacturer, serves to reduce the permeability of concrete in hydraulic constructions or in whose demand it is required. These constructions are prone to the permeability of water and the passage of aggressive agents diluted in it, causing various changes in the concrete. For this reason, this research analyzes the influence of the Sika-1 Liquid additive on water permeability and absorption, as well as other mechanical properties in hardened concrete. For this study, concrete mixtures with water / cement ratios of 0.45, 0.50 and 0.55 were made using Portland cement “Sol” type I and aggregates from the Huachipa and Unicon quarries. All the tests were carried out according to the guidelines of the current NTP and NTC standards. It was obtained that the permeability coefficient is reduced in designs with waterproofing additive up to 93.91% compared to their respective standard designs. In addition, an increase in the resistance to compression and indirect traction of up to 17.97% and 12.71% respectively was observed, also the absorption decreases up to 15.73%. Based on the research carried out under a sample space of 96 specimens for each test carried out under laboratory conditions on concrete with water / cement ratios of 0.45, 0.50 and 0.55, the additive “Sika-1 Liquid“ improves the mechanical properties and reduces the permeability and absorption of the concrete designs studied.
