I have lived in Miami-Dade county for decades. I was here for hurricane Andrew. Had put in a chain link fence with schedule 40 pipe and industrial fabric in 1990. It was the only fence that survived the hurricane. Down here we have coral rock so you don't need much concrete. Prefab concrete fences are very popular here, I bet they will fail as well. Your teasing method is something I used years ago to test a shed. We connected my friend's airboat on a trailer with my Bobcat and hit it from four sides and all corners. The Bull Shed was bull something else and flew apart so they had to replace it. Since you are in Florida I would think it would be interesting to visit your work sometime, I enjoy work as well and love drilling post holes with a skid steer.

Keep up the great work SWI team and John, love it breaking the negative stereotype of driving posts. You have to use these methods in the right conditions and you guys always do a great job 💪🏻

Cool video! As a Florida fence contractor I was all smiles watching this one.

Great video !!! When I worked in site work 2016 -2017 we did a 55 & older Community on valley ridge road in Nocatee Fl. A lot of fill went in that swamp land they built on. A fence contractor put up vinyl privacy fence around the perimeter storm came through blew a lot of it over. They should have went deeper on their line post to get below the back filled grade. A lot of the neighborhoods down there blitz all the trees and back fill it 2,3,4, feet of fill dirt. That goes on every where. Sweet idea with the air boat thanks for the video !!!!!!

I had the idea of doing this a year ago. Cool to see it done lmao. We don't get winds like that here in Michigan, but it's something that I've always been curious about. Great vid!

Cool video. I can’t wait to see the driven posts. People commented my fence wouldn’t last. It’s been through a couple brushes with hurricanes. Well over 50 miles an hour. No issues.

I’ve been to Wyoming a couple times, beautiful country but wow you guys are adapting to Florida quicker than I did. I was living in Saint Augustine last year.

Awesome tests from the Olsen brothers, great fence content as always. I have wanted to do these tests, so glad to finally see it. You guys Should do some tests with the cemented posts with heavy wall posts. We will do our jobs when in high wind area and make all the posts heavy wall. Would be interested to see that done. Have a great dang day and keep up the great work 💪🏻👍👍

8:42 "I wasn't really listening to you. I was just staring at that." HAHAHAHAHAHA

This is a very cool test! I will say that in terms of engineering there’s something called a 3 sec wind gust and that’s what those manufacturer ratings are based on. Not a direct impact for however long you blasted that fence with that sweet looking airboat I might add. There are labs set up to do this exact same test but under very strict ASTM standards and ASCE standards. Also when you have separate sections like this you are creating an end of wall/fence wind load which is 4x greater on the fence than in the middle of a longer stretch of fence.

Good info. Thanks.

LOL i think you guys are a natural to be on TV , what a trip!

What an awesome video! Want to come and do my fence lol

Other than watching Johnny Carson re runs, I get the biggest kick out of your videos! Well done Pilgrims!

I'm a fenceman in Minnesota and I'd like to see this same exact test during the winter. Not sure if Wyoming winters are as brutal as MN but we definitely don't get hurricanes here.

Very nicely did guys! Can’t wait to see the driven post and doughnut, not that kind of doughnut Dan, method.

Dam Good Video! Exactly what you said in the beginning. Everybody says it. But you SHOW IT!!! Awesome! Coming from Guam, USA.

After seeing your vinyl fence presentation I probably won’t put one up I live in Florida I was going to DIY but you make it look like you have to know what are you doing to get it right and my whole yard is sanI guess I to put up shrubbery to avoid the neighbors

Well I know one thing plastic fencing is definitely not the way to go, I live in the UK in a real flat windy part of the country NORFOLK, I've got one section of fencing I put up five or so years ago, I need to put up more as the hedging is dying due to a bacterial intrusion into the soil killing the Privet hedge, I had considered plastic just but it gets brittle in sunlight and that would be most of my fencing facing south, Concrete posts 8 Foot two in the ground with bags of post crete wood leafed overlapping with 3 wood cross members it's not moved and still has Zero wobble and its seen some pretty high winds. Think I'm going to be sticking with my homemade solution buy the wood and self-assemble it with concrete posts.

this is a great test, lots of effort went into prepping, thanks for sharing! do you have something similar for WPC fences? obviously the panels themselves are much sturdier than vynil, but the aluminuim posts are questionable. Wonder if they are succeptable to breakage or bending under heavy wind? Any insight would be appreciated.

That was wonderful work, gentlemen! Very revealing and informative for any fence buyer, builder or observer. It explains why the self-installed white vinyl fence of my neighbor across the street, installed in November, was in my front yard last night. I can't even find anything to be offended about! AND I want to buy one of those enema-meters just for fun. AND we discover ... Dan has hair! Thanks for a great video. Waiting (im)patiently for the next installment.

Love this video

Sounds great information getting ready to do a vinyl fence myself so according to your test doesn't matter if you go deeper this is only a four foot fence and may not fold the post So what would you do for that purpose it's empty post that's causing the problem.

lmao at you guys with that anemometer.

just finished watching both videos, so pounding is strong then cementing?

IM A FENCE CONTRACTOR IN NORTH CAROLINA...AND IVE PUT UP VINYL FENCES...BUT WHEN I INSTALLED THEM I PUT THE VINYL COVERS OVER THE 4X4 WOOD POSTS...I CAN GARAUNTEE THEY WILL WITHSATND THE WINDS....THESE GUYS ARE DOING THIS WITH NO WOOD POSTS INSIDE THE VINYL

I'm in South Carolina 3 miles from the coast (near N. Myrlte Beach area). I have a 6 ft vinyl panel fence In preparation for a hurricane would it be a good idea to take the fence panels off and leave just the posts in the ground during the hurricane? Also, my fence panels keep blowing out during these winter Nor-easters with gusts of 50-55 mph. I've just today put screws in the top rails (there were none). Is that a good idea or is best to let the top rail blowout? Just want to make sure I'm not creating a situation where the panels will break instead of blowing out as the top rail comes lose (as it did in the past without the screws in the top rails).

Hurricane, smuricane, how do those puppies stand up to snow banks? New England wants to know!

My manufacturer says to use 2 bags of concrete per post. Installer used 1 dry bag and tamped it. I've considered filling the posts with concrete. It wouldn't be able to bend over and add some weight to the fence

Great video., Why is wood not used to reinforce the fence? I understand the aluminum option. I thought the vinyl fence would cover a wood frame.

Before it starts the concrete fence failure is at the bottom rail. 73 moh The driven fence failure is in the ground but 82mph.

Good shit

Question for SWI. What if I used iron pipe, with cement 3 foot deep of the same diameter as those galvanized post? How do you feel the iron pipe would hold up? Thanks in advance.

How long did you give the concrete to set before testing?

You should try this test with .250" wall hurricane posts. We install with these and find they don't kink nearly as much as the regular .135" wall.

Was thinking maybe drill a few holes in the bottom of the vinyl post, so the concrete can can set in those holes.

The fence is brand new. How about after a couple of years in strong sunlight? Does it become brittle?

Interesting setup, but were there no posts inside the vinyl? The weakest link is always going to fail. The setting should be engineered instead of guessing from experience. The central buried part adds no resistance to tipping, only the top and bottom. You should have concrete at the bottom and top, not in the middle, as in a barbell shape. Your "properly set" method appears to be opposite of this engineering principle. It seems like temporary bracing with staked wire guys would be more effective in a windstorm than beefier fencing. In my Florida fence, this is how I've gotten 6ft wood fencing to survive 8 hurricanes over the last few decades. Like putting shutters over your plain windows instead of bulletproof glass.

You should do wind load test on cedar privacy set 2 ft vs driven 3-4 ft

Great video, we’d love to have you test it with our foam for a video, Postloc. Let us know if you’d be interested!

40 mph is what I'd consider a breeze myself, and I'm just next door in Idaho.

You built your fence like we do up north. Everything is overkill or nothing

Why not try this test with super saturated ground with water ? Such as what normally happens during a hurricane vs these dry installed post.

AAAAAAAHHHHHH You did a 'TO BE CONTINUED'.... AAAAAAAAHHHHHH 😂 In all seriousness, a timeline recording of the windspeed would be good. So you could see the exact speed of what buckled the fence, and not be mislead by a sudden burst of speed afterward.

Thats how my fence is looking like with these strong winds

I wonder how the fence with poles in the middle of the post would do

these whole time I thought it was the same person just videos from diff states... WTH 🤣🤣🤣

4:50 the f is going on here lol.

I like you test. Your test proves rock or concrete panels are more expensive but more durable. I did not like your eye protection. I would have mounted the meters on a T post before I would chance tearing my eyeballs with debris that gets past your safety glasses. goggles and a face shield preferred. stay safe I have been hurt many times skipping the safety or thinking this is good enough.

I prefer concret fence

😂 👍

I'm convinced to NOT get vinyl. Thanks.
