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.
Ledger board to concrete block.
Yes there are products available for anchoring a ledger board to hollow concrete block foundations concrete masonry unit cmu.
Hold the ledger board in place on the cinder block.
The ledger is not only the structural connection between the deck and the house.
Repeat for each hole making sure that each screw is run all the way in until the head is flush.
Drill two lengths of ledger board for anchors as described above and anchor them both to the solid concrete stacked to provide a 3 wide ledge along the top edge.
2 stage the ledger board flat on sawhorses.
A ledger is typically a 2 by 4 or larger piece of lumber attached to a wall or other surface with the use of fasteners such as nails or screws.
It s also what establishes the overall height and levelness of the entire deck frame.
Ledger boards are used to make joints between lumber structural elements and other materials.
Use the horizontal grout joints between the courses of block as a reference and snap a chalk line across the face of the block at the ledger height.
Fastening a ledger to concrete.
When fastening to uneven stone or stucco the ledger board must be supported from beneath with a ledger attached to the solid concrete foundation at the bottom of the wall.
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.
This wood strip allows other pieces to be joined to the wall with relative ease.
Line up the pilot holes in the board with those on the block.
There are a handful of manufacturers that produce epoxy and other adhesive anchors that are tested for use in hollow cmu.
The threaded rod used with the anchors must be at least 1 2 inch in diameter and must penetrate the block by at least 3 1 2 inches.
