Description
- Weight: 1.4 lb
- Dimensions: 4 in. x 8 ft.
Control groundwater fast with this Flex-Drain flexible expandable drain pipe. The perforated 4 in. x 8 ft. black polyethylene section snakes around obstacles, holds its shape, and snaps tight with soil‑tight fittings that stay put during backfill. Relieve soggy spots and keep flow consistent thanks to staggered slits that admit water gradually.
Work faster with fewer cuts and couplings. Tie into existing lines with broad compatibility across 3 in. and 4 in. corrugated pipe and 4 in. PVC using the appropriate adapters. Count on rugged construction that stands up to jobsite handling and heavy cover.
Key Features
- Flexible, expandable design: Navigate bends and roots without extra elbows.
- Perforated intake: Draw in water gradually for steadier drainage.
- Soil-tight snap fittings: Lock connections that hold during backfill.
- Lightweight build: Weighs just 1.4 lb for easy hauling.
- Durable polyethylene: Resists crushing; exceeds applicable ASTM requirements.
- Broad compatibility: Connect with most 3 in./4 in. corrugated and 4 in. PVC.
Applications
Reduce standing water in French drains, perimeter and curtain drains, and around landscape beds. Run sections along foundations, low spots, and problem areas to move water into gravel trenches or dispersal zones. Use with clean aggregate and, where specified, filter fabric to limit sediment.
