"They completed it in 2 days and I havent had an issue since the basement was waterproofed. However, they did forget to plan the initial inspection prior to the work as part of the permit. The city I live in ended up reaching out near the end of the permit date and I didnt know about it until then. I reached out to the project manager for my project at Acculevel about it and they did handle that issue promptly."
