How to Set a Fence Post. FAST!


00:02 Speaker 1: So there you go, post in
the ground as solid as a rock. [background noise] 00:11 S1: [laughter] That was unexpected. [music] 00:21 S1: Man! The light is [00:24] ____.
Good day knuckleheads, Uncle Knacker’s here and welcome to Video 10, the final in my series
title ‘My Top Ten DIY Tips’ and today we’re looking at how to concrete in a post. Now
that post can be a fence post, a letterbox post or even a basketball ring, it doesn’t
really matter. And we’re using quick set concrete which is a quick drying concrete, also known
as Rapid Set or Quikrete, different names, different countries, different brands. Anyway,
lets stop mucking around, and put this post in. The first step is to dig your hole and
the general rule of thumb is that the depth of your hole should be about one third of
the height of the post above the ground. So this post here is 1500 millimetres so the
depth of the hole is 500 millimetres. And if you got sandy soil it’s good to go an extra
100 millimetres or 4 inches and fill that full of gravel ’cause that adds a good bit
of drainage for the bottom of the post. 01:26 S1: Let’s get this show on the road.
The hole has been dug, we’re throwing our gravel, 100 millimetres of gravel. Well then,
now put our post in. Now before I concrete that post in, I like to get it nice and straight,
nice and plum in both directions. And I do that by using a couple of old sticks of timber
and a couple of clamps. I’ll show you how to do that right now. So hey, get this post
plumb, get your scrap pieces of timber and attach them to either side of this post using
clamps. Now I use clamps you can use screws, you can screw ’em on or you can nail ’em on.
But clamps are good because they are removed quite easily. Now grab your spirit level and
put it on both faces of the post until you get it nice and plumb. And you get a plum
by manoeuvring these braces backwards and forwards. And once you get this post nice
and straight, it’s time for concrete. 02:29 S1: Now today I’m using a quick set
concrete which is ideal for setting posts. Just a quick note, it’s always a good idea
whenever using concrete mix to wear a mask and gloves. The first thing you do is just
grab some water and just flush it around the hole, just to make sure the post is wet and
the sides of the hole are wet. Next thing you do is pour the required amount of water
as stated on the back of the packet into the hole in this case it was two-and-a-half litres.
Now what you do is grab your quick set and pour it straight in, no mixing, around the
place. [background noises] 03:16 S1: Fill in the hole like that. And
make sure you just wash any dry mix off the side of your post. Done. And it’s a good idea
before the concrete starts to set that you re-plumb your post if necessary and then you
can backfill the hole. [background noises] 04:05 S1: So there you go… How to concrete
in a post. How easy was that? Great tip knackers! And keep those braces on for about 20 minutes,
until that concrete hardens up, and don’t hang anything off that post or work on that
post for about four hours. 04:20 S1: So there you go Video 10 done, the
final, finito, all finished. Thanks a lot for watching and as per usual, if you found

  1. Great video. I watch a few videos on this topic and yours was the most sensible and well explained approach I've seen. Go Aussie!!

  2. good video although i would never mix the concrete mix with water in the hole. i always premix it in a wheelbarrow and add the finished mix to the hole. Just works well for me over the years. The idea of clamping boards to the post to help with leveling is one i hadnt thought of….i have clamps and am about to put a birdfeeder post in and that will really help me with the potentially biggest problem…plumbing the post! Thanks very much.

  3. You need to mix the quickcrete with water. I would never just toss it on top of the water and call it good. What I do is pour some water in the hole, pour a bag of qc in, more water then use the post and a narrow shovel to mix it. Also, what's with the clamps, wood and straight level? a post level is much easier.

  4. wood post will rot quickly if you put soil on top of the concrete. I always Made a pyramid concrete around the post about 2 inches and paint it later on so water just drain on the soil not on my post

  5. I am going to concrete (using a quick set concrete) two posts for an access gate between two properties. Instead of timber, I'm using 1.8M x 50mm x 50mm powdercoat pool type fence posts which will have a 1470 x 1200mm gate slung in between. I saw this guy throwing dirt on top of mix and agree with a few others this page if posts were timber they would rot out over time – whether treated or not. So is this method of placing dirt over mix OK for steel as I'm using or should I be taking concrete right up to ground level? I was also thinking of forming it above ground but if it's OK to bury it – then fine. Cheers for any thoughts.

  6. Very nice! I like your video personality. Check out our fence video too.

  7. It is funny the amount of anal people who come on here with all their criticisms and expert corrections. Dude, is showing us a simple method to set a fence post. At some point, YES – the wood will rot, but if you are using treated lumber – it will last a long time. Thanks, Shane.

  8. if you fill with water first, then add concrete, does all the concrete come in contact with water or are you left with bits of dry concrete?? i set a post today and was worried about this

  9. Don't forget you have to make sure the posts are all in line and true with each of the other posts, Any tips on that? thnx Wish I'd watched this this morning, as didn't use gravel and did it the 'use mate to hold post way' Next time I'm doing it your way?

  10. Hi. If I have a 100x 100 post and dig the hole 3 x the width and 1/3 of the height, eg. 1.8m post, the hole has to be 600mm right? But If I need to also include 100m for drainage, the hole should be dug at 700mm deep not 600mm? Is that correct?

  11. Awesome video! I'm setting 2 4x4x8 treated posts. Would the diameter of my hole need to be 12 to 13 in? And should I go down about 2 feet? Thanks mate!

  12. Thanks for the video! I id not know I could do it w/o mixing the quick-crete. This makes the process much easier!

  13. Excellent video and tips! Now do you put concrete on every post when you are doing a fence, or just on your corner posts?

  14. I must have set a hundred posts – by eyeing the post fast against the walls of neighbouring building, what a doofus I am. Thanks for the correct way!

  15. This is very helpful if you have soft dirt with no large boulders, old foundations or tree roots . For "soft guy's" like you !

  16. 1 slight oversight , doesnt look as if that post was treated , linseed oil the post or even wrap it to stall rot .
    you cannot stop rot but you can stall it a good mount of time .. another trick is wrap it with chicken wire

  17. actually you need to add concrete to the top and a little beyond and slope it away from post the way he did it water will collect in that first eight inches or so and eventually rot post

  18. hi ya quick question, do you let the concrete set before filling in hole with dirt? it didnt look like you did I just wanted to check to make sure. Thanks

  19. You get it level by using a couple of old sticks of timber and a couple of clamps? Is there a more modern way to ensure the post is level?

  20. I always like your video's but in my opinion you need to put another bag of crete into the hole as there was possibly a few inches of post below ground level that could rot over time. So maybe make the crete a couple of inches above ground level and round the top of the crete for water run-off.

  21. Please make sure you concrete above the soil level and create a slight slope away from the posts. What I also do is use a highly flexible, temperature resistant clear silicone to go around the edge of the post (like in your bathroom). This will stop the post in hot and cold temperatures when expansion and contraction will happen, from exposing a gap for water to seep into and collect. Another measure you can take (although overkill) is to paint the bottom of the post with bitumen paint a few inches above ground. It works for me.

  22. Thanks for this helpful video. Question; what can I use with regard (concrete) wise for 4×4 Steel Posting? Thanks in advance

  23. Good vid. For those people so worried about wood rot, use steel. If you are then worried about rust, use fibre composite. If you are still worried, maybe leave the fence posts for someone else.

  24. Liked video with exception of u didn't tell how much or how far up you should fill the hole with quick set concrete!!! Help!!!!

  25. I have seen some folks covering that part of the post which remains underground with "Roof Cement". Only the sides .

  26. I need to concrete in the corner posts for a large chook pen. The fencers told me to use rapid set but others, including the packet instructions on some, say don't use it for this or any load bearing applications. Not sure what to do. Thoughts?

  27. I do not understand…if you put the water first all the water will be absorbed by the earth, I think is better to put half water and half concrete ??

  28. Oh no trouble ahead when that bird starts squawking. According to the Mad Max movie. The squawking bird starts before some gets killed

  29. Thanks for sharing your knowledge: your introduction reminded me of "Benny Hill converges with Hee-Haw"! However, the audio was very low even with my speaker setting at 100%: you were almost a silent movie. I didn't consider the boards and clamps for setting the post by oneself. I have to look into a assist like your setup, so I can set a fence post by myself.
