This study presents a comparative analysis of two widely used methods for waterproofing slabs:
asphalt membranes and liquid rubber. The research evaluated criteria such as ease of
application, durability, cost, and environmental impact, considering a realistic scenario
involving a 263.07 m2 area. The results showed that liquid rubber offers greater practicality and
cost-effectiveness, being approximately 32% cheaper than asphalt membranes. However,
asphalt membranes exhibited greater durability, estimated between 15 and 20 years, compared
to 10 to 15 years for liquid rubber. Regarding environmental impact, both materials present
challenges, such as low biodegradability and risks associated with improper disposal, requiring
responsible practices to mitigate negative effects. This study contributes to more informed
decisions in the construction sector, highlighting the benefits and limitations of each material
for different project contexts.
