Footings and Posts

From the measurements in your deck plan, determine the size and location of posts and footings, and mark these points with stakes. Before you dig, make sure that you know municipal building requirements regarding deck footings and where any buried services are located on your property.

Dig holes for posts to a depth of at least 4'. (Deeper holes may be necessary depending on the deck design and frost conditions in your area.) Holes must be wide enough to accommodate a concrete form. Tamp a 2" gravel base into the hole and insert the concrete form. Fill the hole around the form, tamping down the soil.

Fill each form with ready-mix concrete to the desired height. Before the concrete sets, sink the rebar of an appropriate-sized metal saddle into the centre of the concrete. Check that saddles are level and lined up square with the house, and let the concrete cure overnight.

Insert the posts into the metal saddles previously set in concrete. Using stainless steel or hot-dip galvanized nails, fix the posts in place.

Working with ProGuard Preserved Wood

ProGuard™ Preserved Wood
1. All cuts and holes that expose untreated wood should be liberally brush-coated with an end-cut preservative (copper naphthenate in ground contact or zinc naphthenate above ground).
2. Use hot-dip galvanized, stainless steel or other fasteners and hardware as recommended by the hardware manufacturer.
3. Direct contact of preserved wood with aluminum should be avoided. Allow for 1/4" minimum spacing.
