Deck Construction Basics
Below you will find 3D diagrams and illustrations guiding you through the most important steps in deck building in Toronto.
Before you start construction, you need to have a plan showing the location and profile sizes of beams, joists, railing posts, stair stringers, blocking etc. You will also need a detailed footing layout plan showing where the footings need to go and what their diameter is. If you are building your deck in Toronto, you need to make sure that your design, structural member spacing and material selection complies with the Ontario Building Code.
Once you have your footing plan, you need to excavate proper diameter holes (specific to your deck plan and depend on the tributary load area to each footing) to a depth of 4’. To excavate the footing you can either use a hand clam shovel combined with a metal pry bar to loosen the soil and remove stones, rent a hydraulic auger (we do not recommend using a 2 man auger) or hire a company specializing in footing drilling. Once the excavation for your deck is complete, as an option you can put 6” of gravel at the bottom of the footing, then insert a sono tube (so that its top is 6” above grade) into the hole and fill the hole with concrete. You can use the regular concrete mix (cheapest mix available at any building store) and mix it in the wheel barrel. You then need to insert a galvanized metal deck post bracket into the concrete footing on top.
The bracket size needs to correspond to the beam size.Wait at least one day for the concrete to harden before you can carry on your construction. The next step is to attach a deck lag board to the house. If the house is made up of a solid brick or concrete, you need to use 6” long, ½” diameter masonry or concrete bolts. If your house wall is made of siding, veneer brick or stucco, you need to use 12” long ½” diameter lag bolts to attach the lag board to the ledger of your house frame (assuming the deck is roughly the same level as the floors inside the house).
