ADS double wall corrugated HDPE pipe is ideal for drainage projects where flexibility, light weight and low cost are important.
ADS double wall corrugated pipe has kept farms, golf courses, parks and playing fields dry for decades by channeling away excess underground moisture.

N-12 (per ASTM F2648) pipe is engineered with a compound of virgin and recycled high-density polyethylene resins to provide impressive material properties. The performance you’ve come to expect from N-12, with the added benefit of helping to promote responsible use of resources. Available in diameters from 4” to 60” (100 mm to 1500 mm), N-12 (per ASTM F2648) pipe is replacing reinforced concrete pipe as a preferred product for stormwater applications.

Benefits of using N-12 pipe (per ASTM F2648)

• Technological advances in materials science have improved quality of recycled resins. Innovative blending capabilities have made recycled products a viable and often preferred building construction material.
• Mandated use of 100% virgin resin unnecessarily increases end-user (taxpayer) costs. By utilizing engineered compounds, we can maintain the quality and performance while minimizing the impact of excessive raw material increases on infrastructure costs.
• Recycled compounds are capable of providing an equal level of performance. It is socially responsible to utilize them.
• When recycled products are purchased, incentives are created for materials to be collected, manufactured and developed into new products. This process saves resources for future generations.
• The U.S. Green Building Council’s LEED rating program for sustainable design recognizes the use of recycled building materials and LEED credits can be attained for incorporating their use.
• Recycled materials have proven to be viable for construction products. Other widely used construction materials, like steel or concrete pipe, have been utilizing recycled components for decades. 

Applications:

• Culverts 
• Parking Lots
• Paths & Walkway Drains 
• Field Drainage
• Landscape/Subdrainage 
• Slope, Edge, Foundations
• Golf Courses Downspouts/Roof Drainage
• Sports Playing Fields 
• Waterway Terracing
• Grain Aeration 
• Land Reclamation
• Pond Overflows & Dams 
• Irrigation Ditch Enclosures

FEATURES/Benefits:

• Available in varying stick and coil lengths depending on the diameter. Longer lengths result in fewer joints
• Easy-to-handle, safe, lightweight pipe requires less labor and equipment for faster installation and reduced costs
• Provides superior resistance to chemicals, road salts, motor oil and gasoline - will not rust, deteriorate or crumble
• Withstands repeated freeze/thaw cycles and continuous sub-zero temperatures

Joint Performance:    Soil–tight
Joining System:    Split couplers
