fence posts, quick dry cement & rainy weather
|
|
|
| Hello,
I need to install some fence posts.
I'm in Florida and we're in hurricane season.
That means it rains almost every day, when the weather man is right.
Or the weather report says we'll have scattered showers for 4-5 days
and that will occur , or depending on where you are located
it could rain every evening, or afternoon, but not all day .
[my point is, it might rain, it might not]
I was considering using a fast drying product like QUIKRETE=AE
Fast-Setting Concrete or Pakmix Fence Post Mix with PakMix fast setting
accelerator .
In the hopes of setting the posts in the holes when it isn't raining ,
pouring the concrete, & it will dry as it says it will quickly.
[I'm not attaching the fence for a few days until the posts are
secured]
My questions:
1) if the product says it sets in 20 minutes, does that mean if it
starts
raining later that day, it will be ok ?
2) the ground is wet around here.
Is that going to compromise the drying of the cement or the anchoring
of the posts?
what is the easiest product to use, for quick drying cement for the
purpose of fence posts.?
The posts that were previously holding up my wooden fence were done to
code (supposedly):
8' posts, 2' of which is in cemented in the ground - the last category
3 hurricane knocked 4 of the
fence posts out of the ground & part of the fence over.
So I want to do the replacement posts properly & soon.
I cannot wait until after hurricane season to do this.
Thank you.
All help appreciated,.

| My understanding is that concrete doesn't "dry". It reacts chemically to
water and hardens. Concrete can be poured and set under water (bridges).
I don't think rain will affect the process.

| You're making too big a deal out of just fence posts. Most of us
just dig the hole, set the post in it and dump the dry mix into
the hole keeping it down an inch or so, pour a little water on top
and let it do its thing. Keeping the mix fairly dry is stronger
than too wet anyway.
I have a neighbor who dug the holes shy of where he wanted the
fence top, set his pipe posts in line where he wanted them and
with a block on top, drove them into the bottom clay about 3
inches. That locked the bottom. Then he filled the remainder
with old bricks and rubble up to about 3 inches of the top, poured
2 inches of concrete around the top. The fence has been there for
over 30 years now and still straight. <G>

OP above dashed line
---------------------------------------------------------
Wooden fence has alot of sail area, as opposed to a wire fence. Water
saturation of the soil is also a factor.
Rain water intruding into the concrete mixture before its set can be problem
for the surface finish, but not the bulk of the mixture.
Concrete adheres to the subsoil components. If its wet/mushy and/or very
sandy, the resistive capacity to horizontal movement is much less. A
slightly wider and much deeper footing will be more resistant.
Sizable rocks and bricks can assist in intially placing the posts before
pouring. Use caution though. The fill can prevent setting the post plumb.
Keep the fill well below the anticipated height of the concrete.

| I've never used concrete for fence posts. It just causes more problems than
it solves. Try using regular old river sand. Everytime it rains it repacks
your posts.

| Cube sand vice rounded beach sand is a good thing. This kind of sand is the
major component, next to water, in quicksand. Would not stand chance
holding up wooden posts of a wooden fence in a Cat 3 hurricane.
The repack doesn't occur until the moisture dissipates. If nothing is
disturbed during the high moisture condition, all ends well.

| I've only been building ranch and other fence for about 58 years so I might
not be as experienced as the rest of you, but we always use sand and have
never had to reset a post, while with concrete we usually have to reset them
after a long drought followed by a good rain. But, use what you choose. I
just responded with my suggestion.

Just when I think I have heard it all..........
I cannot speak as to the hurricane issue but the concrete in the
conditions you described should be fine. I would think that the surface
area of the fencing as mentiond below is the issue not so much the
posts. They are going to catch an enormus amount of wind perhaps a
different fence design, as in a space between boards to let the wind
through. If you put the posts deeper with more concrete they may just
snap off id look into a different fence design.
