There are many ways to tie timber posts to foundations or wood floors. A few are detailed on this page. The most important thing in designing a timber post base is to keep the post bottom dry and well drained. The design in the photo above is excellent. An example of a poorly designed stone surround can been seen here. All of our post bases are engineered to meet the individual needs of each project.

BROWSE THE TYPES OF POST BASES
Post Base with Steel Rod and Washer
This is one of our favorite ways to tie down columns. A threaded steel rod is epoxied into concrete and drilled into the bottom of the post. The rod extends up to a mortise, and is bolted to a plate washer. A plug hides the connection. We like this joint because it is hidden while resolving both lateral and uplift forces. A galvanized steel plate or pvc spacer is used to separate the concrete and the wood.
Post Base on a Plywood Deck
In this connection, the bottom of the post has a 3/4" stub tenon that is routed into a plywood sub-floor. Log Hog screws are used to hold the post to the solid blocking below.
Post Base on a Steel Stand Off
Here, a custom steel base boot creates a stand off so brick flooring can be installed below the post.
Post Base with Steel Boot
A simple and classic connection. A steel boot is bolted down to a sub-floor and the post is bolted into the boot.
Post Base with Steel Bracket
This connection is nice because it partially conceals a steel boot. The bottom of the post is countersunk to allow for the anchor bolt heads, and the hidden back plate bolts to the post. Both lateral and uplift loads are resolved.
