How to Build a Composite Fence How to Build a Composite Fence
Installing a composite fence does not require any more or less work than installing a traditional fence. The main factor that would make it easier, is that you can purchase composite fence material in prefabricated segments or sections, that can easily be mounted to your main stabilizing fence posts. You will want to make sure that your fence posts are properly treated and coated to prevent run off water from rotting them over time at the base. Your fencing should be easily mounted to these posts once they are installed and secure, with very little effort.
Step 1 - Map your Fence Line
Calculate how much composite fence you are going to need to do the job, and then figure out the amount of posts you will have to install to make your fence sturdy. When using fence panels, which is sections of fence that are already constructed, you will want 1 fence post for each end of the panels length. For example, if you have 4 foot composite fence panels, you will need once post every 4 feet to secure them. Each panel attaches to the half way point of each post and continues on down the row until it is completed.
Step 2 - Start Digging the Post Holes
Start on the far right or left corner of where your composite fence is going to be mounted. You can then determine where your first post will be. You can attach this to your home to add stability, or to other existing structures. With this starting point in place you are going to continue measuring the distance of your posts, marking them as you go. The height on your fence will determine how deep a post hole you are going to have to dig. You want the posts at least 1/3 of its length underground to provide the stability needed to hold up your composite panels.
Wood does not stick to cement, and water will run down your posts and into the post hole pooling around it over time. This can cause rot and instability in the composite fence posts over time. To prevent this, it is suggested to coat the bottom of your poles with tar before pouring in cement footers. This will help the post stick to the cement, and also assist in keeping drain water from penetrating the post itself. It is a good idea to dig out a bowl or ball shape in the bottom of your post holes, so the cement creates a ball around the base of your pole, forcing water away from its base.
Step 3 - Installing Composite Panels
Once the posts have dried, you can then install your composite fence panels. Make sure that when installing the posts, that you have the flat surfaces pointing in the correct direction to allow the attachment of your panels. You can now simply measure how high you want the panels mounted on the posts.
