When the Texas heat knocks out the power, a backup generator can be a lifesaver. But before you fire it up, there’s a crucial first step many Houston homeowners overlook: the concrete pad. Don’t let a faulty foundation compromise your home’s essential power. Generators are large machines with many moving parts that need the stability of a concrete pad. This blog’s purpose is to guide Houston homeowners in determining the correct concrete pad size for their new generators.

Why a Concrete Pad Is Essential

A generator can be a good asset to your home, just in case the power goes out. However, they do require to be placed on a concrete foundation, and for many reasons.

• Stability: A concrete base prevents a generator from tipping, shipping, or vibrating during operation. An uneven foundation can affect the frame and other components of the generator.
• Protection: Typically, a concrete pad is elevated from the ground to avoid any type of corrosion and debris. It is especially necessary in Houston because of the flooding, humidity, and other damage.
• Support: A generator can weigh hundreds of pounds. Therefore, a concrete pad can help distribute the weight evenly.
• Code Compliance: There are several codes to follow, whether from the local authorities or the generator manufacturers’ installation guidelines. These codes and guidelines often do require a concrete pad for permanent installation.

There are several reasons why a concrete pad for your generator should not be neglected. However, in order to ensure maximum security and efficiency, the matter of what size the concrete pad will be also matters.

Determining the Correct Size

For a home generator, there are several considerations to get the correct sizing.

• Manufacturer Specifications: The manual is the primary source for the dimensions of your generator. Typically, the measurements can help with access for maintenance, stability, and proper ventilation.
• Generator Dimensions: It is essential for you to measure the dimensions of the generator’s base to get an idea of how big the concrete pad should be. It is also suggested to leave more room around the generator (about 6 or more inches) for good airflow and easier access for maintenance purposes.
• Example Calculation: If your home generator is 30”x 40”, the suggested measurements for a concrete pad would be 36” x 46”.

A concrete pad for a home generator is more important than some people think. Local codes and regulations are also a factor when it comes to your concrete pad.

Local Code and Regulations in Houston

 Like many other additions to a home, a concrete pad should be in line with any codes or regulations in the Houston area.

• City of Houston Permitting: Permits are typically required for generator installations, such as electrical and plumbing permits.
• Reference Resources: It is always advised to check with the City of Houston’s permitting office or your local HOA for other regulations you should follow.
• Consequences of Non-Compliance: Improper installation and failure to follow the codes can lead to fines, filed inspections, and safety hazards.

Following the codes and regulations can benefit you and your home generator in the long run.

Pad Thickness

The concrete pad thickness is essential to your home generator. Having proper construction and thickness is a crucial part of the overall operation of your generator.

• Minimum Thickness: The suggested thickness for a concrete pad is typically between 4 to 6 inches.
• Reinforcement: Adding reinforcement with a steel rebar is highly recommended for added strength and to minimize cracking, especially for larger of heavier generators.
• Proper Base: A strong concrete mix around 2500 to 3000 psi is ideal for a home generator.
• Professional Installation: It is recommended to consult a qualified concrete contractor for the best base and proper construction.

Calculating pad thickness is a straightforward process when accounting for different factors.
