Culvert Pipe Double Wall 20'

Culvert Pipe - Various Sizes


Explore our selection of double-wall culvert pipes engineered for strength, reliability, and long-lasting performance. These corrugated HDPE (high-density polyethylene) pipes feature a rugged exterior wall paired with a smooth interior surface — combining superior structural support with efficient water flow. This dual-wall design delivers excellent load-bearing strength while minimizing friction and potential clogging, making it ideal for drainage, stormwater management, driveways, road crossings, and other civil, commercial, or residential applications.

Why Choose Double Wall Culvert Pipe?

  • High load-bearing strength
    The corrugated outer wall provides excellent structural integrity for buried applications, vehicle traffic, and heavy loads.
  • Efficient water flow
    A smooth interior reduces friction, helping water move faster and minimizing sediment buildup and clogging.
  • Corrosion & weather resistant
    HDPE won’t rust, rot, or degrade like metal or concrete, even in harsh climates and freeze-thaw conditions.
  • Lightweight & easy to install
    Easier handling means faster installs, lower equipment needs, and reduced labor costs.
  • Long service life
    Designed to maintain performance for decades with minimal maintenance.


Debunking Common Myths

 

  • Myth: Plastic culvert pipe isn’t strong enough for driveways or roads
    Reality: Double wall HDPE culvert pipe is engineered to handle significant loads when properly installed and backfilled, making it suitable for driveways, roadways, and heavy-use areas.
  • Myth: Metal pipe lasts longer than plastic
    Reality: Metal culverts can corrode over time, while HDPE resists rust, chemicals, and moisture — often resulting in a longer service life.
  • Myth: Smooth interior pipes don’t drain as well
    Reality: Smooth interior walls actually improve hydraulic performance, allowing water to flow more efficiently than rough or ribbed interiors.
  • Myth: Plastic pipe can’t handle cold climates
    Reality: HDPE remains flexible in cold temperatures and performs well in freeze-thaw environments without cracking.
