Forming Tall Concrete Walls: Tips for Safety, Strength, and Speed
Forming tall concrete walls – anything over 12 feet – requires more than just stacking panels. The higher the wall, the higher the pressure, and the greater the risk. Whether you’re pouring elevator shafts, retaining walls, or tall foundations, proper planning and equipment are essential for safety, quality, and efficiency.
At Forming America, we supply the formwork systems, hardware, and technical guidance contractors need to get it right the first time. Here’s how to approach tall wall forming like a pro.
1. Use the Right Formwork System
Steel-Ply and SurePly systems are excellent choices for tall walls due to their:
• Modular flexibility
• High strength ratings
• Compatibility with strongbacks and walers for added support
Stacking multiple panels vertically is common – but the layout must be reinforced properly to prevent deflection or blowout during the pour.
2. Reinforce With Walers and Strongbacks
As wall height increases, so does lateral pressure. Use:
• Walers to tie panels together horizontally and distribute load
• Strongbacks (vertical beams) to add rigidity and minimize bulging
• Proper tie placement to manage concrete pressure at each lift
Forming America can provide the full system – including ties, brackets, and formwork layout recommendations.
3. Plan Your Form Tie Layout Carefully
For tall walls, spacing and tie selection are critical. We recommend:
• Heavy Duty Loop Ties for congested rebar or wall heights above 10 feet
• Double tie rows at higher elevations to reduce panel stress
• Custom-length ties (up to 30’) if your wall thickness demands it
Not sure what tie layout is right? Our team can review your drawings and calculate spacing for safety and code compliance.
4. Consider Pour Height and Rate
Tall wall pours may be done in multiple lifts or all at once, depending on:
• Concrete temperature
• Pour rate
• Form tie strength
• Panel bracing capacity
If pouring continuously, watch your pour rate (vertical feet per hour) to avoid overloading your forms. We can help you determine maximum pour rate for your specific system and setup.
5. Safety First: Access, Platforms, and Bracing
Tall walls require elevated work. Make sure to:
• Include work platforms with proper guardrails
• Plan for safe access ladders or scaffolding
• Brace walls against wind loads and vibration
We supply all required forming accessories – including brackets, platforms, and anchor hardware.
