After our pigs escaped the electric net fence AGAIN, we were seeking out better ways to fence them in. Andy Gale of Bay Area Recycling for Charities mentioned that they had an abundance of pallets and we could use them to build a perimeter pallet fence. It seemed like a great idea to me, especially considering that most of the fencing I was pricing out was in the range of 1000s of dollars. Pallets are freely available in large quantity, they’re strong enough to put up with a beating, and also tall enough so the pigs can’t get over them.
I did some Google searching and came across this clever design on the Permies.com forum. Permies is my go to resource for a wealth of information. The basic idea is that instead of burying posts in the ground, as most fences do, you make a pallet fence that stands upright by design by attaching pallets together in an “HHHHH” pattern.
So I tried it out right away. I was even able to track down some long pallets so that fewer “support” pallets were needed. It has worked great all winter long, and it’s strong enough to walk on or even do parkour on!
It may not last as long as a metal fence, but you sure can’t beat the price! I don’t mind patching up the pallet fence every now and then with some of the cast-off slab wood (bark wood) from the local saw mill.
The perimeter pallet fence is just an extra level of protection. Most of the time the pigs will be contained in smaller electric wire plots, within the larger pallet fenced area. This is so that they don’t destroy the fence by using it as a scratching post or try to dig under it.
- Easy/Quick to build
- Recycled (Low embodied energy)
- Can be easily moved/reconfigured
- Sturdy (You can do parkour on it)
- Not as long lasting as metal
- Will get destroyed by pigs if not protected by electric fence
- Too low to exclude deer
- Wont exclude small rodents like rabbits and mice
- Not as visually appealing as store bought fencing
- Many trips to town to haul enough pallets
- Pallets (long and short)
- 3 or 4 inch deck screws (exterior grade)
How to Build a Pallet Fence
Simply place each pallet perpendicular to the previous one, and try to line up some of the thicker frame wood if you can. Screw them together in a few places using the long deck screws. Voila! A self-standing fence!
How many pallets do you need for 100 ft of fence?
Well, it depends! Although there are some pallet standards, you will probably find many different shapes and sizes. Your best bet for consistent sizes is to find one source of pallets in town where you can access them freely, where they have them in large quantity, and all of the same style/size. If you’re using the 40x48 inch pallets it would take about 44 pallets to make a 100ft fence. But if you can acquire some of the longer 8 or 10ft pallets, then you’ll need much fewer.
Where do you source your pallets from?
Pallets are usually found in abundance in most towns in the US and most other industrial towns and cities. The best place to look is where there are many large box/chain stores like Home Depot, Lumber companies etc. Sometimes they will leave pallets out at the road for anyone to take freely, or you might have to inquire about them inside. Usually you’ll see a stack of pallets from the road.
I found the long pallets at a local sign making company, and a roof shingle dealer. Some companies will want to return their pallets because they get a deposit, but often they’ll have cast offs. And some companies will even let you take freely as many as you want. It’s best to develop a relationship with the guys who work back in the inventory if you’re going to be getting them regularly.
I’ve noticed that while most pallets are quite light, and the slats are made of pretty thin wood, every once in a while I’ll find a nice heavy oak pallet that feels like it will last extra long. Keep on the look out for these gems!
Are you concerned about treated vs. untreated pallets?
This is something to be concerned about. In order to kill any bugs that might be living in the wood, pallets are either heat treated or treated with Methyl bromide. Permaculturalist Jenstotland provides some details on methyl bromide:
Methyl bromide has the potential to ‘gas off’ as elemental bromine, after which it acts as a serious ozone depleter. I’m not sure if methyl bormide or its products enter food, compost or soil but exposure to it is dangerous and the effects are cumulative. During the Montreal Protocol talks, in which substances causing ozone depletion were banned, methyl bromide got an exemption when the pallet industry argued that it was necessary to their trade and to prevent the spread of harmful species. All except Canada, who still doesn’t treat their pallets with anything except pressure and high temperatures. [source]
The treatment method is indicated on the side of the pallet with the IPPC logo. Pallets treated with Methyl bromide would have “MB” stamped on it, while heat treated pallets are stamped with “HT.” It would also be wise to avoid pallets used by any food industry which might harbor dangerous food-borne pathogens like e-coli or listeria.
