Slide 3 of 13
- Construction of typical post & pier house
- Uses wood posts spaced at 4 to 8 feet apart along the exterior perimeter walls to support the vertical loads from the floor and walls above.
- The top ends of these posts are typically toe-nailed to a wood girder that is part of the floor framing.
- The bottom ends of the posts are usually supported on individual foundation pads, often called pier blocks.
- Pier blocks:
- These pier blocks are usually concrete, in a pyramid shape, with a square flat top surface where the post is supported.
- The bottom of the post is typically toe-nailed to a wood block embedded in the top of the pier block.
- The pier block may or may not have a larger square concrete pad below it embedded in the ground.
- In the figure, note the presence of posts supporting the house and absence of perimeter footing.
