SRW DF1.5 Drainfield Fabric
Keeps a Drainfield Flowing for Decades
A 1.5 ounce spunbond polyester drainage fabric made for septic drainfields and French drains. It filters fines out of the water entering the stone bed while resisting punctures during backfill, which keeps a drainfield flowing for decades instead of silting shut.

Quick Answers
Why fabric around a drainfield?
It keeps soil fines out of the stone bed. A drainfield that silts shut is a five-figure repair; the fabric that prevents it costs less than dinner.
Is it strong enough for backfill?
It is made for exactly that: high puncture resistance during stone and soil placement.
French drain: how do I wrap it?
Line the trench, place pipe and stone, then fold the fabric over the top so the stone is protected from every side.
