Answer: Cement or concrete
Explanation: A cement or concrete pad is the most durable mounting option for a standby generator because it provides a solid, permanent, and weather-resistant foundation that won’t shift, settle, or deteriorate over time. Concrete pads handle the generator’s weight, vibration, and long-term outdoor exposure better than other options.
Comparison
Cement or concrete — strongest, longest-lasting, resists erosion, ideal for all climates.
Composite/fiberglass — good for smaller generators, lighter, easier to install, but not as rigid or permanent.
Gravel bed — inexpensive and quick, but can shift, settle, and allow moisture intrusion, reducing long-term stability. | | EcoWise Electric LLC | Answer: Cement or concrete

Explanation: extremely heavy, least likely to move | | My Electrician | | | ProMatcher | Answer: Not sure
Explanation: We mostly use concrete but have also used gravel | | Advanced Electrical and Energy | Answer: Gravel bed
Explanation: I like gravel encased in pressure treated box, this way when it rains water goes into the ground, but concrete or composite is fine also. | | DiBiagio Electrical Construction llc | Answer: Composite/fiberglass
Explanation: Composite works well if the area that the generator is being placed is level. | | Dependable Generators | | | ProMatcher |
