It can be cut down onsite to match the installation needs of your fence.

Installation is pretty straight forward. First, dig a trench at the base of the fence, drop the dig guard in the trench and then attach to the bottom of the fence with screws and washers (not included). Finally, backfill around the barrier.

Connecting HDPE Pieces

There are two ways to connect multiple pieces of HDPE together. One method is to overlap the HDPE and use our double sided seam tape to connect the two pieces. The other method is to butt the ends together and use our 17 mil single sided seam tape to create a solid connection.


Overlap Method
(for underground installations)

The overlap method is best used when connecting two pieces of HDPE in a buried application. Due to the overlap, a ridge is exposed which is not ideal when installed in exposed vertical or flat installations in high traffic areas as there is a possibility of an object catching on the ridge and pulling the two pieces apart.

In a below ground installation, the large overlap area provides a more water resistant connection as well as enhanced protection against tree and plant root intrusion.

End to End Method
(for exposed installations)

When installing HDPE on a wall, floor or anywhere that is exposed, the end to end method provides a secure connection and does not leave any ridges exposed to potential catching by a person or object.

    How to Prevent Your Dog From Digging Under Your Fence

    There are ways you can prevent your pup from digging under your fence. Some of these solutions are going to take time to carry out, but in the long run, it will be well worth your time to keep your best friend safe!

    Fill In Holes You Might Find

    Dogs can become very attracted to a hole in your yard. They will dig and dig to find something hidden in the hole or if it leads somewhere else. It's really important that you fill in holes when you find them. If your dog is attracted to a particular area, you might want to fill in the hole and then cover the area with landscaping or yard fixtures.

    Bury The Lower Section Of The Fence

    Dogs can be persistent! If your dog constantly tries to dig under the fence, it's time to stop it once and for all. You can bury the bottom area of the fence one or two feet under the surface so he cannot slip under it and slide out.

    If your dog is an expert climber, and you have a chain-link fence, bury large rocks near the fence line or place obstacles to deter his insatiable habit.

    Attach A Deterrent To The Bottom Of The Fence

    You can attach a small amount of chicken wire to the bottom of the fence to form an added barrier that he cannot dig through. For a more durable solution, add a small strip of plastic fencing at the bottom of the fence so it will be difficult for your dog to dig their way out.

    Pour Concrete

    It's pretty well-known, dogs cannot dig through concrete so this is a great choice to keep your four-legged friend from getting out. The downside, concrete can change the landscape of your yard and could be rather expensive but it's probably one of the best deterrents to keep your little friend at home.

    Dog-Friendly Sprays

    There are sprays that are safe for pets to stop your dog from even getting near your fence. You can test the product on an area of the fence that is not visible in case any discoloration happens to the wood or the materials. Also, you can try using diluted vinegar near the base of the fence to stop digging but it's not a choice that works with all dogs.

    Provide A Place Where Your Dog Can Dig

    In some cases, offering a place for your dog to dig that's safe, is a good alternative. It could prevent him from digging where he is not allowed. You could try a sandbox to see if you can stop him from digging holes. Keep in mind, digging is a very rewarding practice for most dogs. There are many dog owners who have found relocating their digging habits can be easier than stopping all digging altogether.

    That said, it might take some time getting your dog to redirect his digging habits to an approved spot before he gets it.

    Neutering Or Spaying Might Be An Option

    There are many cases when dogs will try and dig out because they are looking for a mate. Getting your dog neutered or fixed could stop the urge to get outside the fence.

    Your Dog Needs Physical Activity

    In many cases, dogs do not get the adequate exercise they need to use up excessive energy. Ask yourself if your little friend is getting a good workout to burn off energy. If your dog is getting plenty of exercise, at some point he will relax and probably take a nap. He will not spend his time digging up your fence.

    Good exercise in your dog's life includes:
    • Enjoy longer walks together
    • Spend some quality time in the park
    • Get into agility activities
    • Add more playtime
    • Buy a dog treadmill

    Nose work games are easy to play and your dog will love the games. To play nose work games, you are using your dog's natural abilities to stay mentally active. A simple command could be “seek”. You will need some treats to show he's done a great job. Get in touch with a dog trainer to help you get started. You and your dog will probably have a great time!

    Remove Your Dog's Line Of Sight

    If you are attempting to prevent your dog from digging, there are a few things to keep in mind. One, if you have a chain link fence, he still has great vision of the outside world. You should consider getting a privacy fence to keep him out of trouble. Other methods might include breaking off his line of vision by installing some form of fencing that is solid and include some landscaping.

    Consider An Invisible Fence

    Even though most people will opt for a physical fence, there are invisible fences with technology to signal your dog to stay away from a specific area by sending a signal through his collar. You should contact suppliers who carry these fences to learn how they operate. If you want to go down this road, you will have to train your dog so he understands how the fence works. Again, speak with those who understand these fences. You might consider having both a physical fence along with an invisible fence. You might want to get your vet's opinion on whether zapping your dog is a good or bad idea.

    Take Steps To Make Sure Your Dog Is Comfortable

    Sometimes, dogs will dig looking for some sense of comfort especially if it's too hot or too cold outside. Purchase a dog pool especially if you live in a warmer climate. If your dog is cold, you might want to get a dog house that has a blanket and a pillow to keep him comfortable. Also, when the weather is cold make sure he has a doggie coat when you go for walks.

    Is Something Scaring Your Dog?

    Sometimes your dog will dig to escape because something is scaring him. It's really important you find out what he's afraid of so he will always feel safe and secure in his yard. When your buddy is outside, pay attention to him so you can find out what is scaring him. Granted, you cannot keep an eye on him all day and every day. Consider getting a camera located at a certain distance to see if you can discover what's bothering him. In some cases, he might be suffering from separation anxiety. If that's what is happening, it's a whole new issue. To get some suggestions, you should contact a professional animal behaviorist to find out what's going on.

    You Have Digging Critters In Your Yard

    You might have critters in your yard like gophers and moles. Your dog might be copying their actions by digging or he wants to chase after them. Talk to people who can help you eliminate them from your yard but make sure you do so safely to protect your dog. To get rid of them in a safe way, reach out to professionals that work in pest control.

    Add Some New Landscaping

    Landscaping can serve two purposes, your yard will have some added appeal and you can keep your dog inside the boundaries. Try adding some small trees, shrubs, or rocks. Just make sure you plant dog-friendly shrubs and discourage him from chewing on your new landscape.

    Supervise Your Pup When He's Outside
