To Whom it May Concern, I was watching the "Home Again" Show with Bob Vila today. They were finishing up a plyground area for kids. This is when I first saw this "FIBER DRAIN" being used. It's a flat, tarpaper like material used for drainage of any area. This would also be a wonderful product if used around a foundation, etc., etc.What are the positives & negatives of this Fiber Drain, versus a PVC, CORRIGATED, & a FRENCH DRAIN type of pipe, aside from bending & working with that material? Can this be purchased at any hardware/home repair center?Thank you very much for your time, cooperation & patience in helping me to resolve this matter. Sincerely, Mr. Ron Vargo
