business and finance civil engineering industry# How far apart should concrete piers be for a deck?

**deck**post to locate the fitting position. In general, posts

**should**be spaced no more than 8 feet

**apart**. Somebuilders position them every 4 feet for a completely rigid frame.The maximum

**distance between**footings is determined by thesize of your joist material.

Herein, how far apart should concrete deck blocks be?

Space four interior **blocks** 2 feet **apart**from one another on each trench line. Level the interior**blocks** to your corner **blocks**. You will have two**blocks** between your horizontal corners and three**blocks** between your vertical corners.

**10x10 deck**You

**should**really use 2x8's or 2x10's. For a

**10x10 deck**(small) - you really only

**need**4

**posts**, but you can

**do**more if you're a glutton forpunishment. If you cantilver the

**deck**2 feet on all foursides then you only have 6 foot spans between your

**posts**.

Also to know, how many posts do I need for a 10x12 deck?

The shorter sides—in this case, the 8-footside—will have 4-feet of distance between **deck posts**.The larger 12-foot side will have a **post** spacing of 6 feetat a minimum code requirement. That makes a total of eight**posts** that need to be installed on this average size**deck**.

A **deck pier block** is in many ways just asimplified version of a “precast foundation”, afoundation type recognized by building codes. They're subject toall of the same requirements as a typical **footing**,regardless of not being cast-in-place. The small bearing area of**pier blocks** is limited in supporting much load.
