Sonotube Sono-Loc^® Concrete Forms

Designed for use in water or excessively damp places, Sono-Loc concrete forms are spirally wound in diameters from 18-36 inches. They are made from rigid polyvinyl chloride (PVC), generally in accordance with ASTMD1784, and feature strong I-beam ribs and a double-locking fastening system for an unsurpassed strength-to-weight ratio. This construction gives Sono-Loc concrete forms the versatility to meet a wider range of applications than conventional plastic tubes. Our concrete forms have the strength to stand up to construction site conditions, yet they are lightweight and easy to handle. Sono-Loc forms are impervious to water and highly resistant to acids and soil chemicals.

Seams are fastened mechanically and with adhesives for added security.  Exceptional durability and light weight make Sono-Loc easy to handle, less costly to ship, and less likely to succumb to damage. It can be customized to ½ inch, in both diameter and length, and can be notched or perforated.
