Understanding your local requirements for culvert and drainage projects isn’t always straightforward. Below you’ll find some of the basics you’ll need to know when shopping for culverts, as well as some beneficial tools and resources to help make shopping for culverts an easier experience. These are some of the most common questions we’re asked when our clients are researching culverts, and we hope these resources can help you in your journey.
What type of culverts exist? Which culvert is best?
There are two common types of culverts, Corrugated Steel Pipe (CSP) and High-Density Polyethylene Pipe (HDPE). CSP is available in multiple factory-applied finishes to accommodate the wide variety of performance and hydrology considerations including Galvanized, Aluminized Type 2, and Polymer- Laminated. HDPE BOSS 2000 ranges from 100mm to 900mm in diameter. It combines a smooth interior wall and annular exterior corrugations for gravity-flow drainage applications.
CSP offers the optimum combination of strength, flexibility and performance, and is available in round or pipe arch profiles.
HDPE BOSS 2000 is more lightweight and cost-effective when compared to CSP. While maintaining durability, chemical resistance, and UV resistance.

How do I properly install culvert?
To learn more about the general installation guidelines of CSP, view this Corrugated Steel Pipe Institute (CSPI) installation manual.
The CSPI is the association of Canadian corrugated steel pipe (CSP) manufacturers. An impartial organization that works with manufacturers, engineers, and municipalities around the world to gather data and information.
Our HDPE culverts are manufactured by Armtech, as a part of their BOSS 2000 product line. For Installation steps, view page 5 of our HDPE culvert brochure.

What culvert does my municipality require?
We highly recommend checking your local municipal requirements prior to purchasing your culvert. Municipalities can have specific regulations for where or how HDPE and CSP culverts can be installed.
CSP: Manufactured to CSA Standard G401
HDPE: Manufactured to meet or exceed the cell class requirements of ASTM D3350.
Roadauthority.com offers some guidelines, information, and prequalification’s for specific culverts being used in public infrastructure. They also offer links to the CSP and HDPE culverts available at Ontario Agra. Both our CSP and HDPE culverts are fully certified to meet or exceed municipal requirements.
