PROFESSIONALINSTALLATION
COURSE
• Select a corner to start placing forms
• Work around foundation cutting as needed
• Make cuts on 1” lines & place without wedging the block
• Make cuts on straight forms only• Measure walls and adjust to match
plan, if needed• Zip tie or use Blocklox on all block
in 1st course• Set & plumb door openings as
specified by plan
FIRST COURSE PLACEMENT
REBAR PLACEMENT• Rebar size/position is specified by
engineer or code requirements• Typical overlap is 40 times bar
diameter (db*40)• Place rebar in outside chairs for 1st
course and to opposite position for each course to top of wall
• If using pre-bent corner rebar, splice laps must be db*40
• Allow minimum of 1” concrete clearance between bar & EPS panels
SECOND COURSE• Start at the same corner as first course• Set right hand corner over a left hand
corner to offset joint 16”• Align webs on all courses to match first
course webs• Make adjustment cuts at location chosen on
the first course• Use Block Lock or zip ties between corner
block and adjacent straight• Set horizontal rebar opposite side of 1st
course• Set & plumb window bucks in position if sill
level has been reached
LEVELING METHODSBLOCK TOO HIGH • Trim with a keyhole saw and push
block down into placeBLOCK TOO LOW • Cut EPS shims and shim until level• Fill void under form with low
expansion foamAFTER WALLS ARE LEVELED• Apply low expansion foam at
intersection of wall and footing on both side of forms
• This prevents forms from being moved out of place before the pour
THIRD COURSE
• 1st & 3rd courses have identical block placement
• Continue to check square and level each course
• Attach wall bracing after 3rd course is stacked
DOOR & WINDOW BUCKS
• Needed to maintain correct opening size
• Contain concrete during pour• Used to mount windows &
doors• Can be vinyl, wood or metal• Quantity need based on
opening lineal footage
LINTELS• Lintel reinforcement varies
depending on opening size• Horizontal rebar above
opening is db*40 or per engineering requirements or local codes
• Prescriptive Design of Exterior Concrete Walls contains charts for lintels up to 16’3”
• Always check lintel requirements with local building code officials
UPPER COURSES
• TOP COURSE REBAR PLACEMENT• Set horizontal following alternating
pattern• Set verticals between horizontals to
match dowel spacing or as required by local codes or engineering
• Position verticals in sleeves, if used• Tie verticals slightly off bottom to top
horizontal to hold in center of wall• If top story – finish verticals 3” below
top of wall or bottom of sill plate• If additional story – extend rebar
above wall to maintain lap requirements
UPPER COURSESStack following rules for 2nd & 3rd courses
MECHANICAL INSERTS• Insert sleeves for all wall
penetrations• Cut PVC longer than opening
width• Use PVC with diameter larger
than opening• After bracing is removed,
trim flush with wall• Place all penetrations on the
pre-pour checklist
BEAM POCKETS
• Use laser level to establish elevation• Mark elevation on both sides of form• Add ½” all around to beam dimension• Cut opening thru both panels on 1 side• Cut opening thru inside panel on opposite wall• Brace both side to hold back concrete• Secure with 2x lumber to cover two webs on each side• Insert weld plate, if specified, after concrete is poured but workable• Include depth of weld plate when measuring elevation
