Footing Drawing

Notes

  1. Concrete to be a minimum of 3000p.s.i. (20Mpa), normal portland cement type 10 or type 50 as required, maximum 3/4" (20mm) aggregate, 3" (75MM) slump.
  2. All rebar to be tied at intersections. Follow position diagram.
  3. Footing meets or exceeds National and Alberta Building Code Section 9.
  4. Load to be applied in the middle of the pad. Eccentric loading will significantly reduce the capacity of the footing.
  5. Wesure Support Systems is not responsible for compliance or application of charts (charts supplied as information only).
  6. The minimum 254mm footing thickness is Government (code) mandated.
  7. The soil bearing load capacities have been adjusted to show the load on the columns alone. The total soil bearing capacity has been reduced by the self weight of the footing itself.
  8. Determine the footing size according to Load. You must verify soil bearing capacity with engineer testing.
