The Evolution of Waterproofing and the Rise of Polyurea

This week’s quiz is from Waterproofing through the ages: From ancient Pyramids to modern day techniques. Waterproofing has shaped construction practices for over 13,000 years—from bitumen-sealed vessels in ancient Egypt to advanced spray-applied membranes today. As moisture intrusion remains one of the biggest threats to building durability, high-performance solutions like polyurea are changing how designers and builders think about foundation protection. Take this short quiz to see how well you know the history, risks, and modern applications of waterproofing.
