When is my interlock past repairing?

Richard Sennott¥rsennott@startribune.com] Chanhassen, Mn Thursday 7/22/10 Southbridge Crossing Station which needs some improvements and repairs totaling over $ 50,000. A few of the pavers are cracking up and need replacing

I should probably say that interlock is never past repairing, because I am all about interlock repair. It is my jam. But I can not say that interlock is never past repairing.
