Step 7: Begin Stacking

After the concrete in your footings has set, snap chalk lines and start stacking block. Begin in a corner and work around the structure creating common seams as needed.  The process for stacking pool walls is the same as stacking regular ICF walls.

Step 7: Snap a chalk line on the footings and begin stacking the walls, adding reinforcement per engineering or local codes. Additional rebar can be added to tie footings to the floor.
