There is a 4” PVC pipe buried 11”-20” below grade. It extends from septic tank to distribution box. Can a 6” deep concrete pad (12’x17’ minimum) be installed to hold a 14,000 lb pool on top of it? Looks like 118,5 lbs/ft^2 for pressure, not including concrete pad. I’ve found info to not build on top of the septic tank or drain field but not about this piping.
Using this guidance, I bought roundup poison ivy killer and mixed 1:1 ratio in a cup to brush it on the leaves/stem/cut ends of bindweed vines. I did it at night and then covered up the treated parts with adjacent mulch. I was going to use bags but there were too many. I covered them up because I didn’t want my dogs or chickens to touch the treated parts.
Did I mess up by covering it with mulch? Has anyone tried this method with triclopyr, fluazifop, diquat dibromide?
It’s been a week and the weeded area under 3” of mulch is popping out. Weeds: grass and bindweed. They did several areas. This area I specifically asked to sift out all the roots. I’ve been battling it for many years and thought I’d go professional. Is it reasonable to ask for a follow up? We spent $5,500 (if that matters)
