Last summer on a construction site in Manchester, the foreman wanted to skip the pre-pour check due to time pressure. I said we had to look at the base first, and sure enough, the gravel was spread too thin. Pouring over that would have led to major cracks within a year. He was annoyed about losing half a day, but it prevented a warranty nightmare later. Those little rules exist for a reason, even when they seem like a hassle. It's scary how close we came to a big mistake.

Man, I was totally on your side for years. I swore by those sealant fixes every single time. But last summer mine failed after just a few months and took the whole compressor with it. The repair bill was insane. Now I'm convinced a full replace is the only way to go for real peace of mind.
