construction/contactor help needed
I have a 10,000 gallon cistern that has one wall as part of my utility room. That wall has developed a crack, and I have a leak. I have tried to patch with Quickrete water stop cement, Drylock sealer, and the water stop spray you see on TV. I now have a huge pimple on the wall, but still have a trickle of water. Over night, that trickle leaves a nice puddle.
Any suggestions on what to do to finally seal this(these) leaks? Someone suggested roofing tar.
