When constructing a deck or pier on a lake, it is essential to pour concrete for strong, durable footings that will support both the structure and its occupants. A well-built foundation ensures the longevity of your project. Follow the steps outlined below to learn how to pour concrete footings effectively.
Materials Needed:
- Power hole auger
- Waxed fiber tube
- Concrete mix
- Wooden stakes
- Support posts
- Anchor bolts
Follow these steps to complete your project:
- Use a power hole auger to dig holes for the number of footings required to support your structure. The depth of each hole should depend on the local climate. To ensure the footings remain stable during winter, they need to be at least 12 inches (30.5 cm) deeper than the frost line, as water in the soil freezes. To avoid frost heave, the footings must be placed below the frozen soil. Additionally, the holes should be at least twice the width of the posts you plan to insert [source: Carter].
- Place a waxed fiber tube into each hole. The tube should extend 2 inches (5 cm) above the ground and 2 inches (5 cm) deeper than the hole itself. Position it centrally in the hole, ensuring it can wrap around the pole to be inserted.
- Carefully pour concrete into both the hole and the waxed fiber tube, filling it slowly and intermittently. Occasionally stir the mixture with a wooden stake to eliminate any air pockets.
- Once the concrete is poured, use the wooden stake to smooth the surface for an even finish.
- Before the concrete sets, place your posts into the center of the waxed fiber tube. The post should be long enough to reach the bottom of the hole and extend 2 inches (5 cm) below the pier or deck surface. Secure each post with an anchor bolt for proper centering [source: Vandervort].
