Septic Drainfield Question
I am new to this forum and would like to get some expert advice. If I do not explain things accurately, please forgive me. I just recently had my drain field replaced. My drain field is the Bed type drain field. In my contract, the contractor stated that he would put Fiber Fabric on top of the stone before covering up with dirt. Instead of using the Fiber Fabric, which he called out in the contract, the contractor used Hay instead.
My question is, what are the advantages and disadvantages of both the Hay and the Fiber Fabric? How long does the Hay last? How long does the Fiber Fabric last. Which one is better?
Thank You in advance,
