- Clear access for boom truck (101” wide, even surface)
- The width of the hole must be no more than 41” for poured walls and 41” for block walls
- Hole excavated 8’ wide down the footer, back from the footer 3’ then graded up at a 45° angle
- Hold back any foundation coating 12” from the hole on all sides
- If the wall is block, the last three cores on each side of the opening must be filled with concrete – not mortar
- If you pour the slab prior to setting the stairs make sure there is no ‘over pour’ out the opening and no wood in the doorway
- If you have a poured wall and you have the opportunity, pour 12” high across the opening IN THE SAME POUR AS THE WALLS .
- This leaves no cold joints and after the slab is poured, this becomes your first step.
- The outside surface of the wall must be smooth and plumb.
Things that will void the waterproof guarantee:
Block walls that don’t have filled cores
Floor slabs not poured prior to setting the stairs
Floor slabs poured too short or out the doorway
Things that cost extra:
