@thetopealao: An open deck needs proper protection against water. Before waterproofing: ✅ Get the slope and drainage right ✅ Repair cracks and holes ✅ Prepare the surface properly ✅ Treat outlets, joints and penetrations ✅ Apply a suitable waterproofing system Don’t wait until water starts showing on the ceiling below. Protect the decking before the leakage starts.
