STEP 1
Foundation Hole Positions for Posts
Establish the height of the canopy/carport at the back (wall edge) and the height of the canopy at
the front. The height at the front must be above 2.1m to meet the minimum legal head height
requirement.
Once you have established your height at the front and back, deduct the height at the front from the
height at the back to give you "The Fall" (x). Measure distance 'x' up the wall and position your roof
bar at this height on the wall. Let the other end touch the ground and where that touches will be the
centre of your hole for the foundation.
IMPORTANT: Use roofing square to ensure the bar used is held square to the wall.
STEP 2
Digging of Holes
You can either cast foundations first or dig holes for casting after. (Bolt to or cast in)
Holes or foundations must be a minimum of 300x300x600 deep. This is only a guide. Please
consult a structural engineer for verification
