How to Mount a Wood Post to a Concrete Porch

Adding a roof over a concrete porch is a way to enhance the outdoor sitting area. Whether that structure is fully enclosed or a basic roof covering, it will need some type of vertical posts for support. Using a metal bracket that is mechanically connected to the concrete slab will hold the post rigidly in place. It is recommended to use a rot resistant wood post so you will not have to repair or replace the main supports after years of exposure to the outside elements.

Things You'll Need

• Wooden post to concrete slab connector
• Pencil
• Masonry drill bit
• Masonry drill
• Fasteners
• Screwdriver (optional)
• End wrench (optional)
• Wooden post (rot resistant)
• 2 foot or 4 foot level
• Support braces

Instructions

1. Align the concrete slab post connector according to the overall design plan of the porch addition. Consult with a local licensed builder and any building regulations for the exact details of any main support structure posts. Different areas around the country will have various building codes depending on local climate conditions.

2. Transfer the mounting holes from the connector onto the slab with the pencil.

3. Insert the correct sized masonry drill bit into the masonry drill. The size of the drill bit will depend on the type and size of the fasteners for the metal connector.

4. Drill out the holes in the concrete slab.

5. Position the metal connector over the drilled out holes. Insert the fasteners through the metal connector and into the concrete holes.

6. Tighten the fasteners into place using either a screwdriver or the correct sized end wrench. Various metal connectors will utilize different fastener methods.

7. Slip the wooden post into the metal connector bracket. Secure the post into place using the manufacturer's recommended fastening system for the wooden post to the metal connector bracket.

8. Level and plumb the post into place using either a two-foot or four-foot level.

9. Secure the post in the level and plumb position by holding it with the recommended support bracing.

10. Continue on to the next wooden post and metal connector bracket.

Tips & Warnings

• Support bracing plans can be found at most home center help areas. Different structures will require various bracing methods. Consult the building help desk for information on bracing techniques.

• Follow all local building codes or covenants when making any addition to your home.

• Not all slabs are suitable for making an overhead addition. Consult a local licensed builder to ensure the concrete slab can handle the extra weight.
