New Construction Measurements

New construction process:

Site Prep Diagram

  • Clear access for the boom truck (101″ wide, even surface).
  • Make sure that the width of the hole is no more than 41″ for poured walls and 41″ for block walls.
  • The hole should be 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 you're working with a block wall, the last three cores on each side of the opening must be filled with concrete instead of mortar.
  • If you pour the slab before setting the stairs, make sure there is no "over pour" out of the opening and that there is 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 will ensure that there are no cold joints. After the slab is poured, this will become your first step.
  • Make sure that the outside surface of the wall is smooth and plumb.

New Construction Before and After

Things that will void the waterproof guarantee:
  • Block walls that don't have filled cores.
  • Floor slabs that were not poured prior to setting the stairs.
  • Floor slabs that were poured too short or out of 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.
