A flush mount well cover should have ...

• A. Asphalt
• B. Plastic in base
• C. Concrete in the base
• D. Wood

Answer: (C)

A solid, durable base is essential for a flush mount well cover because it provides stable, long-lasting support and helps keep the cover level and in place. Concrete in the base offers a rigid foundation that distributes loads evenly, resists movement, frost heave, and weathering, and can be sealed around the well to minimize water and dirt intrusion. Asphalt tends to crack and degrade under load and temperature changes, plastic in the base isn’t typically strong enough for lasting support, and wood can rot or be damaged by insects. With a concrete base, the flush cover remains securely seated, reducing tripping hazards and maintaining a sanitary, clean interface with the surrounding surface.
