Drain Pipe Fabric: Why "Cheap & Slick" Isn't the Same as "Heavy & Fuzzy"

You're wrapping perforated drain pipe and notice two fabric types: cheap, slick rolls at the big-box store, and a heavy, fuzzy 10-ft wide commercial roll. Will the cheap stuff pass water as well?

Probably not. The slick material is likely weed barrier (landscape fabric)—designed to block water and roots. Drain pipe needs a filter fabric (geotextile) that lets water in but keeps soil out.

What to Buy Instead

• Pre-slit "sock" fabric made for 4" corrugated pipe. Sold in 50-ft or 100-ft tubes.
• Brands: Flex-Drain, NDS, ADS. Available at real landscape supply yards (not Home Depot/Lowe's).

Installation Tip

Don't try to shove a 100-ft sock on in one go. Cut into 50-ft sections. Slide on like a sleeve. Tape the ends.

Using weed barrier on drain pipe clogs the system within a season. Spend the extra $15 on the right sock.
