Installation on Pre-Poured Footings & Slabs

Attach first row of block to slab or footing with foam glue or metal channel as per manufacturer's instructions. Lay three or four courses of block, then instal first layer of Zonts™. Maximum height between base and bottom of Zont™ layer is approximately 4'. Space Zonts™ 6' on center around perimeter and attach to ICF web with 1-1/2" x #8 flat head screws.

Place straight 2x4 walers in Zont™ saddles and screw attach from below, ensuring 2x4 is touching the wall side of the saddle. Scab 6' length of 2x4 on joints to provide waler continuity.  In corners, scab a 1x4 on top for continuity.

Screw attach 2x4 strongback to right side of the Zont™ through slot with a 1-1/4" - #8 pan head screw. Locate screw at the slot bottom, back off half turn to allow for wall shrinkage. Cut a spacer 3-7/8" in length and place between the base of the strongback and ICF wall. Toe-nail base of strongback to footing screed board or to a 2x4 nailed or glued around the perimeter if the footing lumber is not useable.

Attach kickers to strongback or plywood gusset (for scaffolding) at 5' height. Use 7' or 8' length of 2x4, attaching Zuckle™ to upper end for adjustment. If working off slab, attach lower end of kicker to an 18" length of 2x4 foam glued to slab. If working off ground, solidly drive a stake, place a short length of lumber under the kicker to prevent settlement, and screw stake to base of kicker. Adjust Zuckle™ to plumb strongback (fine adjustment is done later using stringline). Always PUSH wall to align, never pull.

IMPORTANT: never leave a wall unbraced - a gust of wind will cause extensive damage.

Use strongbacks to construct scaffolding, conforming to local code. Never place scaffolding loads on walers, only on strongbacks. Build walkway with plywood gussets or a second 2x4 outside each strongback with a horizontal 2x4 between.

Build balance of wall. At top screw attach a second layer of Zonts™ locating each on left side of strongback. Maximum distance between Zont™ layer is 4'. Install walers around perimeter and screw attach.

Attach 3/4" blocks on the outside end of each wall face, run string line between. Adjust Zuckles™ to align top edge perfectly.

Replumb wall before, during and after concrete pour: plumb corners with 4' or 6' spirit level, plumb wall with stringline.
