Most decks are supported by posts and whatever is underneath that post can be considered a post footer. The essential function of a post footer is to increase the surface area over which the weight of the structure is disbursed. The weight of the deck, usually measured as dead load, live load, and snow load, is transferred downward through the post. By using a footer at the bottom of your post-hole, the weight is spread over a larger area, preventing the post from sinking. AG-CO, a NADRA member, makes FootingPad®, an innovative composite post footer.
Other critical measures related to footers include:
-Compressive and tensile strength of the material used in the post footer
-Size of the footer
-Size of the post
-Distance between the edge of the post and the edge of the footer
FootingPad is thoroughly tested by NTA, an independent engineering lab. FootingPad is ICC code compliant (ESR-2147). Click here for a pdf copy of the report.
FootingPad makes building easier, faster and is a proven replacement for concrete in most applications. See more at footingpad.com
