Sonotube Foundation & Concrete Pier Installation
Sonotube is a brand commonly associated with cylindrical fiber forms used to contain concrete during
the construction of round concrete piers and columns.
These forms can provide a practical way to create uniform concrete piers when cylindrical
foundations or structural supports are specified.
ZoneBolt installs Sonotube forms as part of foundation and concrete construction projects, following
the applicable plans, specifications, site conditions, and structural requirements.
Depending on the project, Sonotube concrete piers may be used for:
The appropriate foundation system should always be determined by the project's structural and
geotechnical requirements.

What Is a Sonotube?
A Sonotube is a cylindrical fiber form designed to contain concrete during placement.
The form creates a round concrete pier or column and can be used above or below grade depending on
the application and project design.
Sonotube forms are available in different diameters and lengths, allowing contractors to construct
concrete piers suited to the requirements of individual projects.
The form itself is only one component of the foundation system. Proper excavation, reinforcement,
concrete placement, alignment, and curing are also important to the finished pier.
How Sonotube Concrete Piers Work
A typical Sonotube pier consists of a cylindrical form placed at the required location and
elevation, with reinforcement and concrete installed according to the project design.
The finished concrete pier transfers structural loads into the supporting soil or other designed
foundation system.
The diameter, depth, reinforcement, concrete specifications, spacing, and number of piers depend on
factors such as:
For this reason, Sonotube pier dimensions should not be selected based solely on general rules or
typical applications. The project plans and applicable engineering requirements should control.
Our Sonotube Installation Process
1. Project Planning and Layout
Before excavation begins, the pier locations are established according to the project plans.
Accurate layout is important because pier location affects the structure that will ultimately be
supported.
Our team reviews the project requirements and coordinates the work with the applicable construction
plans.
2. Excavation
The required pier locations are excavated to the dimensions and depth specified for the project.
Site conditions can vary considerably throughout Los Angeles and Southern California. Soil type,
slope, existing structures, underground utilities, access, and groundwater conditions can all affect
excavation requirements.
3. Preparing the Pier Location
After excavation, the pier location is prepared according to the project requirements.
The excavation must provide the appropriate dimensions, elevation, and bearing conditions specified
by the project design.
Additional preparation may be required depending on soil conditions and the type of foundation
system being constructed.
4. Sonotube Placement
The Sonotube form is positioned at the required location and elevation.
The form must be properly supported and aligned so it remains stable during reinforcement
installation and concrete placement.
The required diameter and configuration are determined by the project plans.
5. Reinforcement Installation
Reinforcing steel is installed according to the structural design.
Proper reinforcement placement, spacing, support, and concrete cover are important components of a
properly constructed concrete pier.
The reinforcement configuration varies depending on the structural requirements of the project.
6. Concrete Placement
Concrete is placed into the prepared Sonotube form according to the project specifications.
Careful placement helps ensure that the form is properly filled and that the concrete and
reinforcement achieve the required configuration.
Concrete placement methods may vary depending on pier size, site access, equipment, and project
conditions.
7. Finishing and Curing
After the concrete has been placed, the exposed portion of the pier is finished as required by the
project.
Concrete also requires appropriate curing procedures. Curing requirements depend on the concrete
mix, weather conditions, project specifications, and other site conditions.
Sonotube Piers for Hillside Construction
Hillside construction is common throughout Los Angeles and Southern California, where properties
may have steep slopes, limited access, existing structures, and challenging excavation conditions.
Concrete piers can be part of a larger hillside foundation system when specified by the project's
structural and geotechnical design.
Depending on the site, hillside construction may also involve:
ZoneBolt provides several of these related construction services, allowing foundation work to be
coordinated with the broader requirements of a challenging site.

Sonotube vs. Drilled Concrete Piers
Sonotube-formed piers and drilled concrete piers are not interchangeable in every application.
Sonotube forms are typically used where a cylindrical concrete pier can be constructed using a
formed excavation or prepared foundation location.
Drilled piers or caissons involve specialized drilling equipment and are often used where deeper or
larger-diameter foundation elements are required.
The appropriate foundation system depends on the engineering design, soil conditions, structural
loads, site access, and other project requirements.
ZoneBolt provides caisson and pile drilling as well as other specialized foundation
services for projects where conventional Sonotube piers may not be appropriate.

Sonotube Piers for Residential Construction
Sonotube concrete piers can be used for a variety of residential construction applications when
specified by the project design.
These may include:
Residential projects can present unique challenges in Los Angeles, particularly where properties
have limited construction access or are located on sloped terrain.
ZoneBolt evaluates the construction requirements of each project and coordinates the appropriate
foundation work with the overall site conditions.
Sonotube Piers for Commercial Construction
Commercial construction projects may also incorporate concrete piers where cylindrical foundation
elements are appropriate for the structure.
Commercial projects can require greater coordination between foundation work, structural plans,
excavation, reinforcement, concrete placement, inspections, and other trades.
ZoneBolt works with contractors, developers, property owners, and construction professionals on
projects throughout Southern California.
When Is Sonotube Installation Appropriate?
Sonotube forms can be an effective solution when the project requires cylindrical concrete piers and
the site and structural design are suitable for this type of foundation construction.
Factors that may influence the choice of a Sonotube pier system include:
A structural engineer or other qualified design professional should determine the required
foundation design.

Frequently Asked Questions About Sonotube Installation
Sonotube forms are used to create cylindrical concrete piers and columns. They can be incorporated into foundation systems for applications such as decks, additions, structural posts, and other construction projects.
There is no universal depth for a Sonotube pier. Required depth depends on the structural design, soil conditions, loads, local requirements, and project specifications. The project's engineering documents should determine the required pier depth.
The required diameter depends on the structural loads, soil conditions, foundation design, reinforcement, and other project requirements. A contractor should follow the dimensions specified by the project's structural design rather than selecting a diameter based on a general rule.
Whether the form remains in place depends on the specific form product, installation method, and project requirements. Many fiber concrete forms are designed to remain in place. The manufacturer's instructions and project specifications should determine how the form is handled.
Sonotube-formed concrete piers can be suitable for certain foundation applications when they are properly designed and installed. The appropriate foundation system depends on the structure, soil, loads, site conditions, and engineering requirements.
Yes, Sonotube-formed concrete piers can be part of certain hillside foundation systems. However, hillside projects often involve additional structural and geotechnical considerations such as slope stability, excavation, shoring, drainage, and access.
A Sonotube pier typically uses a cylindrical form to contain concrete during placement. A caisson or drilled pier is constructed using specialized drilling equipment to create a deeper or larger foundation element. The appropriate system depends on the project's engineering and site conditions.
The cost depends on factors including the number and size of piers, excavation depth, soil conditions, reinforcement, concrete requirements, site access, equipment, labor, and project complexity. The best way to determine the cost is to have the specific project evaluated.
