A concrete pier is a structural element used to support loads and transfer them to the ground. It is typically made of reinforced concrete and is used as part of a foundation system in construction projects. Concrete piers distribute the weight of structures (like buildings, decks, or bridges) to deeper, stable soil or bedrock. Usually cylindrical, square, or rectangular, and they can vary in diameter and depth depending on the load and soil conditions.  Concrete piers are constructed by drilling or digging holes into the ground, placing reinforcing steel (rebar) inside, and filling the holes with concrete.

Concrete Pier Common Uses:

• Building foundations: Support heavy structures in residential or commercial buildings.
• Decks or porches: Provide stable support for elevated platforms.
• Bridges and piers: Transfer loads from bridge spans or waterfront structures to stable ground.

Concrete Pier Types:

• Drilled Piers: Holes are drilled into the soil, filled with rebar and concrete.
• Precast Piers: Manufactured offsite and transported to the construction site.
• Belled Piers: Have a flared bottom for added load-bearing capacity in soft soils.

Concrete Pier Advantages:

• Concrete provides excellent load-bearing capacity.
• Can be used in various soil types and depths.
• Suitable for medium to heavy loads without requiring deep excavation like piles.
