Hi everyone,The objective of my post is to have guidance on how to repair properly a concrete walkaway, and see if it is a possible DIY project. I am a beginner but have access to help.The actual situation is that there is one major crack and other hairline cracks. It seems to have sunked a bit. Based on comments of past owners, it seems the settling is done and the major crack has not enlarged for several years. It is almost non « unleveled ». The walkway thickness is approximately 2 inches.I live in Quebec, Canada with important temperature changes (from -40 to +40 degrees celcius).Pictures here: https://ift.tt/2Zl2YpK questions are;Step #1: Do you believe it needs to be « leveled / jacked » before? If yes, what are my options. I have read about mud jacking is quite easy but may not last long. I have read also about polyeurethane injections. Can this 2nd option absolutely requires a professional?Step #2: What is the optimal way to repair it? I would like to give it a fresh new look by filling the cracks and putting a new « layer » of concrete on top.Thank you very much, via /r/DIY https://ift.tt/30hzENM
