French Drain Man Explains Why Yard Drainage Systems Fail With a Pipe Sock
I want to talk about why we don’t use a pipe with a sock on it. What homeowners and contractors are doing instead of lining the entire trench to create a fully contained French Drain System, They’re going to use this pipe with a sock on it. It doesn’t matter if it’s a white or a black sock. Same things. I guess the thought behind this is dirt won’t plug the pipe if you buy a pipe with a sack on it. Well, that’s great if the pipe is not plugged but all the aggregate between the pipe and the sidewall, the trench, ends up plugged with dirt because of the migration of the stone into the subsoil and the subsoil to stone. It doesn’t really do you a lot of good to have a pipe with a sock on it.
We use a pipe with really, really large saw cuts because we use a large aggregate so we can do that. We move a lot of water that way. We lined the entire trench and then we do what is referred to in the building industry as burrito wrap this entire system. This is a maintenance free French Drain system. Contaminants can’t find their way in.
Now the contractors that are buying this pipe with a sock on it, they’re saving a lot of money. They’re not lining the whole system with fabric. And then they’re not putting as much stone in. They end up putting some of the dirt back in the trench on top of some filthy pea stone that they’re using and then the system fails.
