Resumen

Construction demands solutions that improve durability and reduce environmental impact, and the use of recycled rubber is an alternative aligned with these objectives. However, there is little evidence on its application in geomembranes for lightweight slabs and its effect on structural and hydraulic performance. This study evaluated high-density polyethylene geomembranes reinforced with recycled rubber fibers, integrated in lightweight slabs, by means of permeability, tensile, adhesion, and durability tests according to ASTM standards, in addition to a cost analysis. The results showed reductions in water penetration from 39-42 mm to 25 mm and in the permeability coefficient from 10⁻¹¹ m/s to 10⁻¹²–10⁻¹³ m/s, with sustained improvements up to 91 days, in addition to an increase in the modulus of rupture by an average of 47%. The slight cost increase of 10% is offset by the increased durability, making it a sustainable technical solution for environments with high moisture exposure.
