A park bench can be an elegant addition to any backyard or garden but you want to ensure you perform the installation correctly. When you are deciding on a method of installation, keep your outdoor space as well as your personal needs in mind. Using a solid block of concrete may initially seem like a great idea, but it may pose a danger if you have small children running around in your backyard.
Concrete can effectively secure a park bench. You can create a concrete pad to which the chair can be bolted. Put the pad on a level part of the ground to prevent it from cracking, and also use a layer of stone under the concrete to prevent the bench from sinking. Another option is to use concrete footers rather than an entire pad. Some park benches come with footer posts that you can install two or three feet into the ground onto concrete footers.
You can also use pressure-treated boards or plywood to create a base for your park bench. Dig a shallow trench in the ground where you would like to install your park bench, and then place the boards in the trench. Tightly pack dirt around the boards to hold them in place, and then bolt the park bench to the wood. Once the bench is in place, you can cover the wood with dirt and plant grass over it. If you are using plywood, use wood that is at least one-half inch thick or thicker.
You may not want to permanently install a park bench in your backyard or garden. If you purchase a simple backyard park bench, then you can install pressure-treated boards on its feet and put the bench wherever you like. The boards will help to prevent the individual feet from sinking into the ground, and the pressure-treated wood will be able to withstand the weather. If your bench does start to sink into the ground, then just move it.
