Wood Fencing

Quick Reference

  • All wood should be Pressure Treated to last exposed to the elements
  • Verify utility lines before you dig
  • Fence posts are generally 4x4'
  • Fence posts should not be further apart than 8'
  • Fence posts need to be buried
    • The hole must be as deep as 30-50% of the post's above-ground height
    • Deeper burials provide better rigidity in structure
    • The hole's diameter must be 3x wide as the post used - ex: a 4x4' post is 3.5" wide, requiring a hole diameter of 10.5" 
    • The post should sit flat and level in the hole, and be arrested with collars while concrete or gravel is poured in
    • Fill the hole almost entirely, leaving 4" to be filled with soil
    • Do not attach fencing to posts until concrete is cured

Installing Posts

  • Dig holes for the end posts of the fence
  • Install temporary stakes in the same line as the planned fence
  • Run a length of twine between the steaks, overlapping the dug holes. 
    This serves to ensure that the installed end posts maintain the same facing as one another
  • Flatten the earth at the bottom of the holes, and drop posts within
  • Install Post Collars around the posts
  • Bring the posts level while maintaining facing
  • Pour concrete/gravel around the posts, while performing fine-tuning leveling adjustment
  • Do not lift the posts once concrete/gravel has been added, as the material will slip under the post's base, reducing its depth

  • Wait for concrete to set

Post Collars

  • Collar should be constructed with 2x4's
  • Two boards should run for at least 2'
  • Two other boards should be cut to the width of the post used + 3/16" for tolerance
  • The end result will be a bracket with a hole in its center the same size as the used post
  • It aid in the post holding its position while leveling adjustments are made, and cement/gravel is poured
