ICF Construction in 25 Steps Lessons Step 10: Shim and Trim

Step 10: Shim and Trim

After 2 courses have been laid around the structure, shim and trim where necessary to level the block. Leveling the block at this time will ensure the structure stays level for the rest of the build.

Once the walls are level, spot glue every 18-24 inches. Be cautious of the amount of foam used during this step. Using too much foam adhesive will lift the wall from level and create problems as you continue to stack blocks. Once more block is stacked and the alignment system is attached, a full bead of foam can be placed.

Step 10: After two or three courses have been placed, shim and trim as needed so walls are level and plumb. Spot glue to footings or slab and wait for foam adhesive to set before continuing with your wall.
