It s also what establishes the overall height and levelness of the entire deck frame.
Anchoring ledger board to concrete foundation.
Attaching deck to concrete house foundation drop the ledger level to allow it at least 2 gap between the deck boards top and the bottom side of a door.
One of the benefits of this method is that more rigid minimum and maximum lag screw location configurations associated with mounting to band joists can be avoided.
The fourth technique involves securing the ledger to a concrete foundation wall rather than to the first floor band board.
Cut pieces of pt 4x4 post to fit from the top of the double ledger support to the bottom of the deck ledger above.
Fastening a ledger to concrete.
Even the sagging of joists affects the loads on the anchors of the ledger the sagging of the joists causes a rotation of the ledger board and due to the constraint of momvement caused by the concrete wall the ledger board does not rotate about the anchor bolts but rather the lower edge of the ledger that is in contact with the concrete.
Then install the drip cap over the ledger top of entire length.
On this project the 2 10 joists of the main deck frame sit just about even with the top of the foundation and a landing framed with 2x8s sits atop the main frame serving as a transition point.
Now fit another strip over the drip cap and also under.
