Installation on Pre-Poured Footings & Slabs

- Attach first row of block to slab or footing with foam glue, metal
channel or 2x4s as per ICF manufacturer's instructions.
- Lay three or four courses of block,
then screw first layer of Zonts™ along top edge 6' on center using 1-1/2" #8
flat head screws.
- Place 2x4 walers in Zont™ saddles.
Scab 4' 2x4 over joint for continuity. Scab short length of 1x4 over
corner joint if required.
- Cut spacer 3-5/8" in width for
positioning between the ICF wall and bottom of each strongback.
- Place 2x4 vertical strongbacks on right
side of Zont™, nailing base of plumbed strongback to footing (use
spacer at base to position). Tighten cam counter-clockwise to lock waler and strongback to wall.
- Choose a kicker length so that when at
45º the top end is about 3/4 of the way up the wall. Screw attach
Zuckle™ to top end of kicker and double screw to strongback. The higher the attachment point, the easier it
is to push wall; too high and kicker gets in way of catwalk.
- Solidly drive stakes in the ground at
base of kicker, screw stakes to kicker. If necessary use two stakes at
different angles to increase holding power.
- Screw plywood gussets to each strongback
at height to allow easy concrete placement and finishing. If railing is required,
use short lengths of 2x6 to span between strongback and second
vertical 2x4 to support 2x10 catwalk. Ensure catwalk and railing conforms to
- Build top of wall. Spot glue top blocks
to prevent separation between layers during pour. Use 8" extension on impact drill
to attach top row of Zonts™ beside each strongback. Place waler in
position, then twist cam counter-clockwise to lock 2x4s against wall.
- Align wall by first plumbing corners with 6'
spirit level. Attach short 1x4 blocks on top outside end of each face, run
stringline between. Adjust Zuckles™ to align top edge of wall 3/4" from
stringline. Re-check alignment during and after pour.
IMPORTANT: Never leave a wall unbraced - a
gust of wind will cause extensive damage.
IMPORTANT: Alway PUSH a wall to
align, never pull.
IMPORTANT: Concrete vibration can
loosen cams, check tightness during pour.
