Adjustable Formwork for Circular and Curved Walls
Circular and curved concrete walls, tanks and arches are easy to form with the EFCO REDI-RADIUS® forming system. When multiple diameters are required for a project, EFCO’s REDI-RADIUS® system can be adjusted to any radius with very little labor required. Shaping tables, either convex or concave, are used to adjust REDI-RADIUS® panels.
For extra ease-of-use, REDI-RADIUS® panels can also be pre-shaped to required specifications at EFCO’s warehouse and then shipped to your job site. You may also shape them on your job site. The 6 1/2″ heavy-duty flange on REDI-RADIUS® form panels allows you to assemble panels into large rigid gang sections without stiff-backs, aligners or walers.
FEATURES AND BENEFITS
- The 6 1/2″ deep panel
- Fixture built; excellent panel joint alignment
- Shaping forms to radius
- High-strength form set-up
- No vertical or horizontal walers or aligners required
- Ties may be placed two feet off of the concrete footing

How does REDI-RADIUS® prevent waterstop interference?
Waterstops are no problem when you cantilever the REDI-RADIUS® Form. The 2′-0″ rib REDI-RADIUS® form can be used in a cantilevered configuration on a radius wall to avoid problems with ties interfering with waterstops or any other bottom of the wall obstructions. The 2′-0″ rib form can also cantilever at the top of the form set-up to avoid any obstruction or obstacles encountered at the top of a radius wall set-up.
How do I add a Trough Wall to a Round Tank with REDI-RADIUS®?
EFCO can provide a special all-steel trough soffit panel for round tank troughs to conform to your required diameter. This form is built with 4″ deep ribs located on 12″ centers. Flanges are made of 3/16″ material for added strength and all flange holes are slotted for easy set-up. This trough soffit form is particularly advantageous where you have several trough tanks with the same diameter. REDI-RADIUS® starter forms make it possible for you to finish the concrete at the bottom of a trough, or the slab below a vertical wall.
How soon can forms be stripped?
The duration of time between placing concrete and removing/stripping formwork and shoring depends on a variety of factors, but it is ultimately based on age criteria and the minimum concrete strength determined by the project engineer/architect (reference ACI 347-R14; 5.7.1). Example factors that affect concrete strength include methods of cure, construction sequence, and project schedule. Based on the various criteria established by the project engineer/architect, the removing/stripping time can range from 12 hours to 28 days. The removing/stripping time can often be increased when supplemental concrete supports are used. Examples would include EFCO’s Box Culvert Roof Support System that temporarily supports the top slab of a box culvert while the forms are cycled ahead to the next pour. Another example would be the EFCO Deck shoring system which includes a “drophead” feature that enables contractors to strip joists and stringers early while the posts continue to support the recently placed slab.
Pour Window Access
When a project and or an engineer’s specifications require pour window access to a form set-up, EFCO’s REDI-RADIUS® forming system has the answer. The windows are hinged for easy access, saving time and labor. Each window is approximately 2′ square and is infinitely adjustable to match the radius of the REDI-RADIUS® form set-up.
