That sounds familiar — I tried to relevel a small section of my patio once, thinking it was no big deal. It looked fine for a few weeks until the ground settled again, and the problem came back even worse. Honestly, when you start seeing uneven spots spreading or water not draining properly, it’s better to call professionals.
OAKS Home Services provides the best interlock repair services, and they explained to me that issues like base erosion or drainage problems can’t really be fixed with just sand. They lifted the pavers, repaired the base, and compacted everything properly. The difference was huge — no shifting, no puddles. I learned that if you’re spending time fixing the same spot twice, it’s time to get expert help.
