Hello and welcome to the forum. I help folks with construction, rehab, and leak abatement nationwide and as a volunteer here my time is always free. Holler anytime happy to jump on a call and help review your options moving forward - might be a good candidate for water born polymer seal of which I’ve done over 1000 to date. Will help you avoid all the mistakes I’ve made during pond construction. Again welcome to the forum great to have a NYer around!
