What NOT to do!
• 1 - No or minimal slope on apron
• 2 - Locating the seam directly under the bottom rubber seal of the door
• 3 - Allowing water to flow back into the building through a seam/crack.
(This is a result of failure to follow precautions 1 & 2 above).
IMPORTANT TO REMEMBER
• Saw cuts may cause water to flow back into the building.
• The combination of saw cuts and no slope may cause water to flow into the inside of your building.
Avoid any seams/cracks
under the door frame
