Why Not to Use a Drainage Pipe with a Sock For a French Drain

Here is a roll of drainage pipe with a sock. When you are getting a quote for a french drain, try to avoid using a contractor that uses drainage pipes with socks for a French drain system in a residential backyard. To take care of your surface water in your yard, you want a pipe that does not have a sock. You also want to align the trench so that your stone does not migrate into the subsoil and the subsoil does not migrate into the stone, thus plugging the system.

This might work for some time, but slowly, it will move less and less water, and probably stop altogether.
