Set in concrete: When the existing deck
is 4 or more inches thick, installers may only have to core drill
the concrete to accommodate the anchors or sleeves that connect to
the lift. Always consult manufacturer’s instructions.
On the level: Installers should check
the immediately surrounding deck to make sure it slopes no more
than 1 in 48. The ADA outlines the equation to determine how much
of the deck must stay within this specification.
