In a nutshell

What is ICF bracing?

ICF bracing is a temporary support system. It is made of a strongback, an adjustable turnbuckle, platform bracket and handrail. It keeps insulated concrete form (ICF) walls straight, level, and plumb during concrete pours, while also doubling as a safe working scaffold for construction crews.

What it does

Bracing is the skeleton of a safe ICF pour

ICF bracing designed for use in insulating concrete form (ICF) wall forming applications.

The bracing provides support for builders at the required heights necessary to construct and fill the ICF form cavity with concrete. It also braces the wall unit until it has cured and provides the means to plumb and align the wall before the concrete sets.

Utilizing the ICF bracing allows the contractor the means to build ICF walls fast and straight, while ensuring a safe work environment and providing a professional job site appearance.

  • Resist lateral pressure from the rising pour
  • Align corners, openings and wall runs to tolerance
  • Stabilize against wind and crew loads during the build
  • Recover — steel and hardware strip clean and reuse

Why teams specify it

Built for the realities of the job site

ICF bracing isn’t an afterthought — it’s the difference between a wall that stands true and one that bows under the pour.

Engineered load ratings

The duty rating for each bracing is 300 lbs. each or 2 people per span plus materials including forms and rebar sufficient for three courses.

One-person install

GRAVITY PIN and latch pin let a single crew member square and brace a long wall run fast.

Plumb to tolerance

Integrated turnbuckles give fine vertical adjustment, holding walls within ±¼″ over a full story.

Reusable steel

Powder coated components strip clean and last for dozens of cycles — lower cost per square foot than timber.

Wind-stable

Deep-ground stakes and cross-bracing keep tall, empty forms standing through gusts and storms.

Cleaner site

No nail guns, no cut lumber, no scrap. Bracing packs back into racks and rolls off at completion.

Key components

Every part earns its place

A small set of reusable steel parts makes up the whole brace line. Each is sized, rated and finished for season-after-season site use.

Aluminum strongback for the ICF bracing system

Aluminum Strongback

The Strongback is the main vertical component of the ICF bracing system — a 6063-T5 extruded aluminum channel secured to the wall forms through the provided slots. Use screws to fasten the strongback to the ICF form. Center-drilled through-holes let you independently mount the platform bracket and the telescopic brace to the strongback channel with the gravity pin.

Platform bracket for the ICF bracing system

Platform Bracket

The Platform Bracket is a fixed-position bracket built for strength and durability. A 15 mm diameter hole secures it to the strongback through the matching holes in the channel, and the bracket accepts two scaffold planks.

Platform guardrail for the ICF bracing system

Platform Guardrail

The Platform handrail is a safety guardrail fitted to temporary wall-alignment and scaffolding systems. It prevents worker falls from walk boards during concrete pours and attaches to the platform bracket through an 11 mm hole using a latch pin.

Telescopic brace for the ICF bracing system

Telescopic Brace

The Telescopic brace is the diagonal component of the system, with several fixed adjustment positions. The diagonal turnbuckle brace can be set at different angles to suit irregular excavation elevations, and fine adjustment is made by twisting the turnbuckle. A swivel foot assembly at the base carries the loads; its base plate has holes to anchor the brace to soil or secure it to the footing, slab, or intermediate floors.

Installation & use

How to brace an ICF wall

Follow the steps below for safe erection, bracing and maintenance of the ICF wall system.

Preliminary Considerations of Use

Review plans to determine the number of bracing units required for the project by starting with a bracing unit in the corner.

  • Maximum spacing of the brace is 7 feet (6″ recommended).
  • Do not reduce the number of bracing units relative to the door or window openings. Instead, use additional bracing units to insure adequate support and ability to control the wall in areas where voids may occur.
  • The bracing unit locations should be centered relative to the overall length of the wall, but offset relative to the changes in the direction of the wall. For example, at outside corners the first bracing unit in each direction should be located as close to the corner as form tie spacing will allow. Bracing on the inside corners a distance of not less than 27″ is required for the clearance of platform bracket and planking.
  • For longer and taller walls, bracing on both sides of the wall is recommended. NOTE: WOOD BRACING FROM THE GROUND TO THE UNDER-SIDE OF THE PLANKING WILL BE REQUIRED AT THE CORNERS TO SUPPORT PLANKING OVERHANG.
  1. Prepare the layout of the excavation, footings and wall form location in accordance with the wall designer and ICF installation procedures.
  2. Gather the bracing components within the perimeter of the wall. Ensure that the diagonal turnbuckle braces are set to the fixed adjustment position relative to the intended height of the wall and that the fine adjusters are set to allow equal in and out adjustment of the wall after concrete is placed.
  3. Install a minimum of three courses of ICF forms before erecting the bracing system.
  4. Locate the positions for the bracing units at the base of the wall and center them on the form ties.
  5. Stand the strongback in position and secure it to the footing.
  6. Using two #10 pan head wood screws per course of block, secure the strongback to the ICF forms by screwing into the form ties through the slotted holes in the back of the strongback. The screws should be located at the top of the slot, tightened to allow full compression of the form interfaces, but not allowing the form to float upwards.
  7. Fasten the top of the diagonal turnbuckle brace and platform bracket by using the 6″ pin and keeper pin. Attach the brace and platform bracket assembly to the strongback at the appropriate height location relative to the height of the wall being formed. Refer to the Our ICF bracing system drawings in the back of this user manual. Hold a level parallel to the strongback at eye-level and bring the strongback to within 1.5 degrees of plumb with the wall leaning in towards the perimeter, then anchor the base of the diagonal turnbuckle brace. During this process it may be necessary to adjust the angle of the brace relative to the strongback or even to readjust the fixed position to suit the excavation.
  8. Once all of the strongback, platform bracket and diagonal brace assemblies have been erected, planking can be set in place to continue erection of the wall.
  9. As each consecutive course is set in place, ensure that a minimum of two screws per course is used to secure the strongback to the form units.
  10. As the form stacking approaches the intended wall height, the planking can be moved up to the final position with the planking and handrails in accordance with all applicable codes, and the final course erection and preparations to pour the walls can be completed.
  11. OSHA requires scaffolding, handrails and toe board if the worker’s feet are 6’ or more off the ground. Once the erection is complete, do a final check of the vertical condition of the wall. Ultimately, a slight inward tilt allows for the easiest plumb adjustment after the pour.
  12. Once the wall has been poured, final plumb and alignment adjustments can be made using the fine adjustment of the individual diagonal turnbuckle braces in conjunction with alignment and plumbing measures taken during the process.
  13. Do not remove the bracing or backfill until the wall has reached sufficient cure in accordance with the wall designer’s direction, and intermediate floor and/or roof diaphragm have been installed.

Handling and Maintenance

With an emphasis toward performance, value and ease of use, the materials used in the Our ICF bracing system are the strongest, most lightweight and user friendly we could design. The painted parts of the product are finished by electrostatic coating to provide excellent durability and corrosion resistance.

Reasonable handling and maintenance will result in years of dependable service. Primary maintenance consists of periodic lubrication of the fine adjustment threaded portion at the top and bottom of telescopic brace.
