Why Substrate and Exposure Matter More Than the Product Name Pick the wrong waterproofing chemical for a job, and you're not just wasting material — you're signing up for a callback in eight months when the terrace starts leaking again. With cementitious, PU, bituminous, acrylic, and epoxy systems all sold as " waterproofing solutions ," knowing which one actually fits the substrate and exposure condition in front of you is what separates a one-time job from a repeat client.

Before reaching for a drum of anything, you need answers to a few questions. Is the water coming from the positive side (direct exposure) or negative side (pushing through from inside, like a basement wall)?
