What do you do when you don’t want to use conventional ledger angle methods when using ICF’s?

EASY… use an Advantage ICF Brick Ledge Block!

Advantage ICF brick ledge blocks are unique in that they are the only ICF brick ledge blocks designed as a corbel to provide a continuous 4” wide reinforced concrete ledge to support exterior brick/masonry finishes, floor systems & decks, read on.

When you use the Advantage ICF Brick Ledge the rebar is totally encapsulated in the concrete and there is no chance of oxidation where EPS voids are present. No EPS insulation voids also means less waste when corners are mitered. In some cases, the Advantage ICF brick ledge block can also be reversed to support interior floor, roof systems and slab support. These specially molded blocks are placed at the specified wall height or heights to create a monolithic concrete supporting ledge. Once the proper stirrups/ rebar are placed and the blocks are braced and you are ready to place concrete.

ICF Brick ledge blocks are commonly used to support brick and stone exterior finishes. They can also be used to support hollow core precast concrete panels for suspended garage floors and commercial buildings. An increasing number of trained contractors are using these blocks to support floor systems. Using a brick ledge block instead of supporting the floor system on top of ICF walls with an exterior rim board will greatly increase the effective R-value of the wall system.

Typically brick ledge blocks are at the top of the wall section that you are pouring but they can be capped off with dimensional lumber if you wish to continue higher and pour all at once. Special consideration must be taken when pouring walls above the Brick ledge block elevation to ensure concrete doesn’t overflow the 4” gap at the brick ledge block elevation that creates the support.

Here is How to finish the Advantage ICF brick ledge blocks. The use of top cord bearing trusses incorporated into the design will “hide” the corbel detail in the webbing space. Some contractors and home owners will build a bulkhead or drop ceiling to run utilities under the corbel or they attach drywall matching the profile to create a unique detail similar to a crown molding.

Advantage ICF brick ledge blocks are rapidly becoming the ledger system of choice.
