DIY French‑drain fix
A simple French‑drain hack using holed PVC pipe, rocks and a slope to direct patio runoff is getting shared as a cheap fix for heavy rains — step-by-step DIY guidance is in the viral thread (x.com). With severe storms forecast across large parts of the U.S., directing water to planted areas can prevent patio flooding and save landscaping costs ( ).
Multiple short-form videos and how-to posts that reproduce the holed‑pipe, rock-and‑slope approach appeared across TikTok and YouTube this week, with creators testing the technique on patios and driveways. (tiktok.com) (tiktok.com) Landscape and engineering guides recommend a continuous pipe pitch of about 1/8–1/4 inch per foot (roughly 1%–2%) and typical residential trench dimensions of about 10–12 inches wide and 18–24 inches deep for reliable flow. (engineerfix.com) (engineerfix.com) Retail pricing shows 4‑inch corrugated perforated drain pipe at roughly $0.70–$1.62 per foot on big‑box sites and perforated Schedule‑40 PVC around $2.86 per foot, while washed drainage gravel currently runs about $10–$50 per ton depending on region. (homedepot.com) (homedepot.com) Nationwide cost guides put DIY material totals at roughly $10–$30 per linear foot and professional installs at $25–$65 per linear foot, with a 100‑foot exterior French drain typically running $1,000–$6,500 once excavation and labor are included.
