Best Way to Replace 19mm Poly in Concrete Path with 25mm Blue Line?
Planning irrigation for my garden. House has 19mm poly going directly into concrete path. Wanting to replace with 25mm blue line to run to a valve box for irrigation.
What will be the best way to do this, and approximate cost?
Current thinking is to remove the 19mm poly and coring the existing hole in the concrete to ~90mm and running stormwater pipe through. Would then be able to feed blue line through. Other option is cutting a strip of concrete out. Open to all suggestions. Cheers
