I have learned so much from your videos...we are water scarce here in Australia too and watching your simple and effective ideas has been so worthwhile. Thank you.
Hi there, I have a big METAL water tank here from 60.000 liter. But it has big rusty parts and I noticed today drops came out from the side. This tank is very important for us and I wondered if I could repair it with concrete with lots of waterproof in there. What do you think. Friendly greetings from the south of Spain
