Articulated Waler Forming System

Articulated Waler
Forming System
Build the radius forms
you need with the beams
you already have… then
turn the screws to change
the radius and start
forming again… fewer
parts, more versatility,
lower cost and a smooth
concrete surface.
Build and reconfi gure the forms you need
with the joists or beams you already own.
Radius forming from 20’ to 180’,
with 3/4” plywood, aluminum joists or
wood beams, and adjustable walers
Curved concrete structures and tanks never seem easy
to form, and changing radius and wall dimensions only
add to the complexity.
It becomes a real advantage to build and then
reconfi gure the radius forms you need, especially with
the aluminum joists or wood beams you already own.
The Articulated Waler forming system provides that
advantage by connecting the beams, fl exing the radius
and spacing the ties.
Imagine starting with 3/4” plywood, aluminum joists or
wood beams, connecting hardware, and the Articulated
Waler, then building the radius forms you need to meet
project specifi cations.
Standard taper ties or she-bolts, with fl at washers
and nuts, complete the forming assembly. These ties
are widely available and reusable, but spacing must
conform to the rated tie capacity.

Build the forms you need, then
change the radius and start forming
concrete all over again
When using Aluma or Safway joists, an A-Clamp
assembly is used for the waler connection. When using
Symons joists, a Symons Aluminum Beam Clamp is
used for the waler connection. When using H20 wood
beams, an H20 Beam Flange Clamp is use for the
waler connection.
Steel angles or fi ller angles are used as the side rails.
Consecutive form segments are positioned, clamped or
bolted together, and braced for support.
Longer joists or beams can be mixed or staggered
with shorter lengths and used for taller walls. Scaff old
Brackets with walkways can be attached to the joists or
beams for access and concrete placement.
After building the radius forms you need and placing
concrete, you can strip, move and reconfi gure them for
the next phase of the project.
Radius forms can be reconfi gured to match
changing radius and wall dimensions.

1. 2. 3. 4. 5. 6. 7. 8. 9. Articulated Waler Gang Assembly
Note: The contractor is responsible for all required lumber, beams, plywood, fasteners and tools.
Construct the exterior gang on a fl at, relatively level, working surface. A concrete slab or shop fl oor is
suitable. The dimensions will depend on the gang size, structure radius, and type of aluminum joists or
wood beams. (SureBuilt can provide recommendations, drawings and spacings.)
A typical exterior gang will be 8’ wide x 16’ long. Lumber sleepers are placed/squared on the slab for the
top, center and bottom of the gang. The center line for each joist/beam location, starting 6” from the edge
and spaced 12” apart, should be marked on the lumber sleepers.
A typical exterior gang will have eight joists/beams. Check the bottom fl ange dimension of the joist/beam to
determine the center line and spacing. Use wood spacers to block the joist/beam to the centerlines marked
on the lumber sleepers.
Start the exterior gang assembly by placing the joists/beams between the wood blocks. The joists/beams
should be straight and in good condition. The attachment rail should be facing down (waler side of gang)
and the nailing strip should be facing up (plywood side of gang).
Place and center 3/4” plywood across the joists/beams and fasten to the nailing strips with 2” drywall
screws at a maximum spacing of 12” on-center. Be sure the plywood and gang remain square during the
plywood installation.
Fasten steel angles along the vertical edges of the exterior gang. When using SureBuilt Filler Angles along
the vertical edges, fasten the Filler Angle and a 2×4 lumber stiff ener behind the plywood with a 1/4”x 2-3/4”
elevator bolt/nut at 12” on-center.
Tie holes can be marked according to the drawing and drilled with a paddle bit or hole saw (drilling through
the face minimizes splintering). The tie spacing and hole size will depend on the type of tie and rated
capacity. (SureBuilt can provide recommendations, drawings and spacings.)
Turn the gang over (use a nylon strap through the tie holes) and lay it over 4×4 lumber centered along
the entire length of the gang. This will support the center of the exterior gang and cause the unsupported
edges to sag, starting the radius.
Mark the position for each Articulated Waler across the joists/beams, typically starting 18” from the bottom
of the gang and spaced 4’ on center. With the Articulated Waler in a “neutral” position, place the “fl at” side
against the joists/beams and clamp top/bottom at each intersection.
10. Construct a jig to support the exterior gang at the desired radius. Place the gang on the jig and use the
adjustment screws to “fl ex” the Articulated Waler to the desired radius. Make small adjustments to every
screw on every waler, gradually and evenly shaping the gang.
11. Once the desired radius is established, tighten all the clamps. Attach any other hardware, including scaff old
brackets, walkways, guardrails, brace shoe, and lift brackets.

12. The interior gang is constructed following the same procedure outlined above, though the gang will be
slightly less than 8’ wide. The plywood must be trimmed to the smaller width, allowing for the smaller
interior radius and proper exterior form alignment.
13. Construct a jig to support the interior gang at the desired radius. Place the gang on the jig and use the
adjustment screws to “fl ex” the Articulated Waler to the desired radius. Make small adjustments to every
screw on every waler, gradually and evenly shaping the gang.
14. The number of Articulated Waler gangs needed will depend on the structure dimensions and construction
cycle planned by the contractor. Pre-assembled gangs can be stacked and staged until needed.
15. The Articulated Waler is reusable. It should be cleaned, oiled and properly stored when not in use.
