What is the purpose of the sock on drain tile?
Correspondingly, why are drain pipes perforated?
Here, the perforated pipe has two functions: collection and conveyance, with the latter being the primary function. I place the pipe with the perforations facing up and count on the streaming water from the downspouts to help keep silt and debris from accumulating in the pipe.
Similarly, should I use landscape fabric in French drain? It is also best if the French drain trench is wrapped in permeable landscape cloth (the type water flows through) and the pipes are covered in drain sleeve fabric to further slow down any clogging by roots or soil particles.
Similarly, it is asked, does bend a drain with sock need Stones?
Yes and no. Your French drain works by doing two things: filtration and drainage. The sock around the pipe acts as a filter to keep fines (silt and clay) from clogging the pipe perforations and the pipe itself. So if you have a sock pipe you can use pea gravel or 78M stone.
Where does drain tile go?
Drain tile is a perforated pipe that allows water to enter into the pipe. It's installed at the base of a foundation. Water in the soil flows through washed gravel on top of the pipe and is carried away from the foundation where the pipe exits the ground.
