Concrete Products From Sepulveda Building Materials

The superior strength-to-weight properties of Sonotube forms prevent blowouts and may eliminate the need to use a crane during setup. Contractors around the world know Sonotube round concrete forms stand strong in their superior technology and value.

Sonoco, the market and technology leader in the design and manufacture of concrete column forms, features water-resistant Sonotube concrete tubes with RainGuard technology, including round, square, and finish-free concrete forms.

Sonoco’s new Sonotube brand forms incorporate a proprietary, high-strength, water-resistant paper that allows contractors to set them in wet weather and pour concrete the next day. This gives contractor's added scheduling flexibility to complete construction projects on time.

Sonoco has leveraged over a century of paper-making experience to re-engineer its Sonotube concrete column forms. The outcome is a proprietary fiber form with improved strength, toughness and durability in wet conditions that has resulted in superior strength-to-weight properties and the virtual elimination of “blowouts” – the most frequent mode of failure of wet fiber concrete tubes.
