Engineering advice for waterproofing an infinity pool in Brazil

Pool Waterproofing Expert Needed for Expert Advice (Concrete Pool) I'm looking for an experienced pool engineer or waterproofing specialist to advise on the waterproofing of a concrete swimming pool. The situation: the pool structure is built and the concrete is done. We're now at the stage of deciding how to waterproof it before the finish goes on, and I want expert input to make sure we choose the right system and execute it in the right order. I'm specifically looking for someone with real, hands-on experience waterproofing concrete pools, not general construction. I want honest, practical advice: which system you'd recommend and why, the correct sequence of steps, the common mistakes to avoid, and what to insist on for a long-lasting, leak-free result. What I'll share once we connect: photos, dimensions, the soil report, and the details of the structure so you can give a grounded opinion. To apply, please tell me briefly: - Your experience with concrete pool waterproofing specifically (examples or projects welcome) - Your general approach to deciding on a waterproofing system - Whether you're comfortable reviewing photos and documents and giving clear, honest recommendations This is an advisory role. I value straight, experienced opinions over sales pitches.
