Fill vinyl fence post concrete.
But if you have even the slightest gap in that fence post the cement will slip out.
If you want to keep grass from growing around the posts trowel mounded concrete slightly above grade so water will drain.
For line posts this is generally sufficent for fences five feet or less in height.
The result is an extremely solid concrete post that extends from below the frostline to 2 feet above grade.
Below grade and pack in soil on top of the wet concrete.
Let s use an example to illustrate what we covered above.
Note that 4 posts are actually 3 in diameter.
Any screws driven through the pvc become embedded in concrete and the rebar ties the two pours together.
Using concrete with vinyl fence posts is most definitely the best way to ensure that your vinyl fence will last a lifetime.

Once you ve finished digging your post holes add about three to four inches of gravel into the bottom and compact it using a post or a 2x4.
If a new fence installation is in your future contact best vinyl to get a free estimate.
Use the formulas above for volume.
If you pour the dry concrete into the post and add water i would say that would be much less effective as pouring in wet already mixed concrete.
If you check hopefully your corner and end posts are filled with concrete but generally line posts are not.
Installing a vinyl fence.
For fences over five feet and for solid fences such as privacy fences that buffer a lot of wind you should rebar and fill each line post with concrete as well.
Therefore 2 of post will be in the ground.
Let s say we are installing a 6 fence.
Gravel is sometimes used under vinyl fence posts not for drainage but to provide a footing in soft soils so the hollow post doesn t sink into the soil over time.
An alternative is to keep them out of the ground and fill the holes to ground level with concrete.
Racking a vinyl fence.
The mistake most homeowners make though is thinking that a 3 foot deep hole equates to setting a post 3 feet deep.
Otherwise stop filling the holes with concrete about 4 in.

Plan your fence and follow the rules.
Our vinyl fence installation experts at future outdoors always set vinyl and wood fence posts 3 feet into the ground for our 6 foot and taller fences for extra stability and strength.
