In this video, Canadian Contractor contributing editor Steve Maxwell (“Stuff We Like”) provides a detailed description of the perfect post saddle installation for a deck.
Steve recommends 12-inch diameter footings, because you have a bit more leeway in aligning the posts properly.
He also recommends you use footings that are wrapped in black polyethylene plastic. Why? Because the polyethylene wraps prevent “frost jacking.” Frost jacking is where frozen soil grips and lifts the footing. In a cold climate like Canada, that is a serious concern. You definitely don’t want your deck footings to be lifting up out of the ground. The polyethylene wrap makes the footing too slippery for Jack Frost to get ahold of.
Steve also recommends using “hot-dipped galvanized” U-channels on the top of the footings. Don’t use plain steel ones. Even the electroplated channels don’t provide the corrosion-resistence that hot-dipped galvanized hardware will provide. Same deal for the carriage bolts: use hot-dipped galvanized ones.
There are lots more tips on this video.
If you’re going to build a deck for a client, do it the right way – this way – on the footings and hardware connectors.
