This was built by professionals?

This picture speaks for itself. Believe it or not, the home owner is not happy, and the contrctor will not return. Unfortunately this is the misinformation and installation we face in the industry. We have already rebuilt this pond. unfortunately it will not be the last disaster we come across. Just remember, just because you are paid for a job, it does not make you a professional. Personal note: Flagstone is for patios, and in rare cases, the negative edge. We threw it all away.
