Wall Types Possible With the Monowi System
Add Your Own Adaptations!
Monowi System Corner Set For Walls Over 4’ Tall
Whaler bracket
3 Dbl hd 16d nails
Leak proof, rust proof
non-conductive ties.
2x4 whalers @ 16” O.C. to wrap corners
Retainer brackets
Vertical 2x4 whalers at
plywood joints
2x4 nailed to one side of corner
set
Lap horizontal whalers PAST first plywood joint on
outside form and secure at first whaler in second sheet
with double head 16d nail to contain end pressure.
Retain corner assembly pieces for ALL pours. Change
dimension of inside form ONLY for varying wall
thicknesses. Make up all odd lengths in “run” of walls
using 2x4 whalers to span the odd opening and fill in
with “scrap” or cheaper plywood.
Make outside corner faces so that concrete is some
“modular” length (24”, 32” or 48”)
48” O.C. Balance of wall
Vertical 2x4 whalers
located at plywood joints
Tie holes
drilled from
pattern sheet
CAUTION
NEVER use Monowi Forming accessories with LESS THAN
BB Grade Yellow Pine or Douglas Fir species, 5 ply FORM
plywood of ¾ inch thickness on walls over 48” high. DO NOT
use chip boards, CDX, or other inferior grades as they will
NOT distribute and bridge the pressure load evenly between
the ties. This could result in a form failure.
Pour all concrete in 2-3 ft. lifts. Vibrate each lift separately
and do not vibrate down through previous lift. Use maximum
3-4 inch slump concrete. (These are really just STANDARD
rules for any concrete form pour!)
Tie ends must make 3-POINT contact with retainer and whaler
shoulders. If not, you 1/3 of the tensile strength.
If whaler or retainer clips have a cracked “keyhole” they
should be discarded. If the shoulders become worn or
rounded they should only be used near the tops of formwork.
Wear eye protection when breaking off tie pin ends.
If you are using plasticized concrete – it will increase your
form pressure about 400%! You MUST pour in lifts and wait
for an initial or partial set.
