4" Perforated Corrugated Drainage Pipe with Filter Sock – 100 Ft.

Build a longer-lasting underground drainage system with this 4" Perforated Corrugated Drainage Pipe with Filter Sock – 100 Ft. The perforated pipe collects excess groundwater from surrounding soil and drainage stone, while the built-in fabric filter sock helps prevent soil and sediment from entering and clogging the perforations.

This all-in-one 100-foot roll is ideal for French drains, wet lawn areas, landscape beds, retaining walls, and other drainage applications where groundwater needs to be collected and routed away. The flexible corrugated design makes it easier to follow gradual curves and adapt the pipe run to your landscape.

For best results, install the pipe in a properly graded trench with suitable drainage stone. The filter sock provides an added layer of protection for the pipe, helping maintain water flow over time.

FAQs

What is the filter sock for?
The filter sock wraps around the perforated pipe to help keep soil and sediment from entering the pipe and clogging the drainage openings.

Is this good for a French drain?
Yes. It is an excellent option for French drains because the perforations collect groundwater and the sock adds filtration protection.

Can I use this for a downspout extension?
This is generally not the best choice for downspout extensions. Downspout drainage typically uses solid pipe to carry roof water away without allowing it to escape along the pipe run.

Do I still need drainage stone?
Yes. Drainage stone, such as #57 Stone, helps water flow through the trench and into the perforated pipe. The filter sock protects the pipe itself; it does not replace a properly prepared drainage installation.

Can I connect this to other 4-inch drainage products?
Yes. Use compatible 4-inch fittings, elbows, lock couplers, and adapters to complete your drainage layout.

Do you deliver drainage supplies?
Yes. We offer flatbed delivery throughout Metro Atlanta, including Alpharetta, Roswell, Milton, Johns Creek, Suwanee, Duluth, and surrounding areas.
