• 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:
Return trip fee if the site is not ready
Digging fee if the site is not dug out properly
Replacement fees if the wrong size unit was ordered
