We had a water leak in our basement in 2005. We used a TV camera and thought we had a faulty perimeter drain. I was ready install a new weeping system. Tri-State sold us an interior perimeter drain with a lifetime guaranty. In July 2010 we had water again. I brought in an engineer and found out the problem was that there wasn't cement around the septic pipe going through the cinder block. So their system cost me $ 8,053, when all I needed was a simple cementing repair in 2005 and the damage in 2010 to the finished basement cost an additional $ 1,917. So in total we spent $ 9,970 instead of $ 250. That's a ripoff!
