Footing must be straight, flat and level with a tolerance of +/- ¼” and meet local building codes. Building materials and ICF block should be stored at least 8’ inside footings to allow space for bracing. Snap chalk lines for placing block on the footings. Fasten starter track to footing. Lay out all doors and windows on footing or floor according to plan before building. |

 |
| Begin by laying a corner block onto the starter track and continue around the footings until the first course is in place adding horizontal rebar in the first course and every odd course following. At the start of the succeeding course begin by placing first corner in the opposite direction of the existing course corner to interlock all corners. |

 |
| Insert door bucks at the beginning stage of stacking block. Window sizes vary so determine where the bottom of window buck will start. Draw the opening of the window on the block using a marker and cut out foam with a circular saw, then insert window buck. Make wall penetrations for utility or mechanical entry and exit points. Install appropriate plastic or metal sleeves. |
| |
 |
| After six courses, attach upright steel bracing to vertical track. Attach a turnbuckle arm to each upright and secure to the ground or the floor. Placement of bracing should be as follows: two braces per corner and braces no further than 10’ apart thereafter. Place appropriate planks and rails according to safety specs. Window and door bucks also need to be braced with 2x4’s vertically and horizontally. |
| |
 |
| Start by making sure all corners are plum using plum stick and level. If necessary, adjust turnbuckles until plum. After corners are plum, square all window and door bucks. Then attach string line and straighten walls by adjusting turnbuckles. |

 |
| For the concrete we recommend a boom pump and the use of a double 90° or reducers to slow pouring velocity. Reddi-Wall ICF is certified to be poured in ten foot lifts. While pouring place vertical rebar into wall. Spacing varies according to rebar thickness and code. Internally vibrate under windows and after each lift. |
| |
 |
| Cut openings for electrical boxes and channels for wiring with a hot knife or electric chain saw. Make wire channel depths in accordance with electrical code. Make plumbing channels in a similar fashion. |
| |
 |
| Reddi-Wall ICF walls take interior coverings like gypsum wall board, plaster, wood, etc. and exterior coverings like stucco, wood, metal, vinyl or cement fiber siding, brick, stone or EIFS. Finishes can be applied using mechanical fasteners and/or adhesives according to local building code. |
