Dual-Wall HDPE Culvert 18" × 20'

A 18-inch double-wall HDPE culvert for driveway and roadway crossings. Smooth inside and corrugated outside, each 20-foot length has a bell-and-spigot end, so it joins the next pipe without a coupling band. 

18-inch inside diameter, 20 feet long

• Superior Drainage Flow Capacity: The smooth interior bore minimizes friction and debris buildup and boosts water flow capacity compared to corrugated metal alternatives.
• Double-wall HDPE provides structural stiffness and superior strength for a long-lasting solution that will carry heavy loads across roadways
• Advanced Durability: Built from High-Density Polyethylene (HDPE), a highly resilient material that eliminates rust concerns compared to metal. Eliminates structural cracking vulnerabilities common with handling, transporting, and shifting heavy reinforced concrete pipe.
• Corrugated exterior helps hold the culvert in place.
• Self-Coupling Joint Design: Built-in bell-and-socket system allows for rapid, secure connections with no split bands or extra tools required.
• Install today, and your driveway or roadway is ready for immediate passage.
