Building a notched post for a durable composite deck structure
Technical note: Installation details vary by municipality, product line, board profile, fastening system, loads, and site conditions. Use this article as general guidance only; confirm the final design with your local building department, the manufacturer's current installation guide, and a qualified contractor or engineer when structural loads are involved.
To ensure the strength and longevity of a composite deck in Quebec, it's essential to master the connection between the post and the beam. A precise notch locks the beam, prevents its rotation, and resists uplift from wind.
Steps for cutting and securing the post notch
- Measure and Mark: Precisely transfer the notch dimensions onto each 6x6 post.
- Initial Cut: Use a circular saw with shallow depth to notch the top part of the post.
- Notch Finishing: Use a reciprocating saw or hand saw to clean the notch and achieve a clean angle.
- Treating Cuts: Apply a coat of copper naphthenate to the cut surfaces to prevent rot.
- Pre-drilling and Bolting: Pre-drill and install two ½” carriage bolts to lock the 2-2x10 beam into the notch.
