Concrete Forms: What You Need to Know

Concrete forms, also known as form tubes or column forms, are important in construction for shaping and supporting poured concrete until it sets. These cylindrical forms provide a smooth and even finish, reducing the need for additional shaping or corrections. Available in various widths, these forms accommodate a variety of structural and decorative applications. Whether you're installing fence posts, deck footings, or creating structural columns, choosing the right size ensures efficiency and durability.

Concrete Form Widths & Best Uses:

  • 8 in: Ideal for light-duty applications such as fence posts, small sign bases, and minor residential supports. This size is commonly used in landscaping projects where smaller, reinforced concrete footings are needed.
  • 10 in: A versatile option for deck footings, mailbox posts, and medium-sized sign foundations. The slightly wider diameter provides additional stability without requiring excessive concrete volume, making it a cost-effective choice for backyard and commercial installations.
  • 12 in: Designed for structural support applications like porch columns, pergola footings, and foundation supports. The 12-inch width provides increased load-bearing capacity, ensuring durability and strength in medium- to large-scale projects.
  • 14 in: Best for heavy-duty commercial applications, such as load-bearing columns, foundation piers, and industrial-grade structural supports. This size allows for larger, reinforced concrete pours, ensuring stability in high-load environments like warehouses and commercial buildings.

Applications:

  • Foundation Footings: Concrete forms provide a solid base for decks, pergolas, and other outdoor structures by ensuring proper weight distribution. Using the correct form size helps prevent shifting and settling over time, maintaining long-term stability.
  • Structural Columns: These forms are commonly used for residential and commercial concrete pillars, offering a smooth and professional finish. Reinforced columns created with form tubes provide additional strength, making them essential for load-bearing applications.
  • Fencing & Signage: For fence posts, road signs, and mailboxes, concrete forms ensure uniformity and proper alignment. They help keep posts securely in place, preventing leaning or instability due to environmental conditions.

Key Features:

  • Minimal Waste & Cleanup: Pre-formed tubes allow for precise concrete pouring, reducing excess material waste. Once the concrete is set, the forms can be removed easily, minimizing post-installation cleanup.
  • Easy Removal & Finish: Once hardened, the forms can be peeled away cleanly, leaving a smooth and professional surface. This eliminates the need for excessive finishing work, saving both time and labor costs.

Concrete Forms FAQ

 What are cardboard form tubes used for?

Round form tubes, often made of heavy wax‑coated cardboard, create cylindrical footings, piers, and columns. Builders use them to form foundations for decks, porch posts, and fences. The forms are cut to length, placed in excavated holes, and then filled with concrete. Once the concrete cures, the cardboard is removed or allowed to decompose.

What diameters and lengths are available?

Supply Ontime stocks tube forms in diameters ranging from 8 inches up to 24 inches. Standard lengths are 4 feet, but they can be cut on-site to the desired height. Larger diameters provide greater bearing capacity for patio covers, light posts, and small retaining walls common in Los Angeles landscaping.

Can Sonotube forms withstand Los Angeles’s hot, dry summers without losing shape or strength?

Yes. Supply Ontime’s Sonotube forms are engineered to perform reliably in the intense heat common to inland Los Angeles and the Valley. The outer moisture-barrier coating resists softening under direct sunlight, and the multi-layer fiber construction holds its rigidity even during extended pours in 90-degree weather. Contractors across Southern California favor Sonotube because it stays stable, peels cleanly after curing, and maintains a perfect cylindrical shape, even when jobsite temperatures fluctuate between cool coastal mornings and high afternoon heat.

Does Supply Ontime deliver concrete form tubes to job sites?

Yes. Form tubes are lightweight but bulky. Supply Ontime delivers them by truck within hours or on a scheduled 2‑hour window. For multi‑story buildings or downtown projects, indicate elevator access or staging areas so delivery teams can efficiently place the forms near your work area.
