• Multiple forms can be prepared for simultaneous pouring.

Bracing:

• Achieving plumb alignment is straightforward with minimal bracing.
• Light timber or existing scaffolding can maintain form alignment during pouring.
• For tubes up to 225 mm in diameter, brace every 2.5 meters.
• For tubes 250 mm in diameter and larger, brace every 3 meters.

Pouring:

Formatube forms allow for a single lift pour using standard methods, with a recommended rate of no more than 4.5 meters per hour and pressure below 14 Kpa. While a release agent is optional for Formatube forms, it's advisable for harsh concrete mixes.

Curing:

Leaving Formatube forms in place enhances moisture retention, reducing seepage, absorption, and evaporation for optimal cement hydration and curing.

Stripping:

Quick and effortless, typically recommended 1-5 days post-pouring. Stripping methods include:

• Two vertical cuts along the column using a power saw, then removing the form.
• A 30-cm vertical cut with a linoleum knife, followed by spirally peeling using a broad-blade tool.
