How do I install a DIY Fence or Wall?
Homeowners are increasingly taking matters into their own hands and saving big on labour costs, cutting their project expenses in half. If you’re looking for a new wall or fence, our DIY fence and wall systems were specifically designed for the DIYer with a keen eye for style.
Installation is fast and easy, and you won’t need any heavy machinery, specialist trades or to waste your whole weekend on strip footings. In fact, you can erect your new wall or fence in a single weekend, with the entire process simmered down into 4 simple steps:
- Dig post holes
- Concrete posts in
- Insert panels and capping
- Finish as desired
1. Dig post holes
Measure out your site simply by using a tape measure, some string and pegs, sticks or even chopsticks! To start, place your first peg (or stick) where your first post will go, with the stick representing the post centre. Then, measure out the appropriate spaces between post centres, marking all post centre placements with pegs. Wind your string around each peg, ensuring that you are creating a straight line; this will later act as a guide to ensure your wall is straight.
Next, using a post hole digger, dig the holes where each post will sit, moving the peg or stick just in front of the hole but still in line with the post centre.
How deep should I dig my post holes?
- Typically, the depth of the hole being 1/3 of the overall height. So for a 1.8m high wall or fence, you’ll need to dig post holes at 600mm depths.
- However, this can change for certain wind regions or sites with sandy soil. If this applies to you, let your ModularWalls consultant know and they can advise accordingly.
- The width of the hole should also allow for 50mm of concrete around each side of the post.
2. Concrete posts in
To prepare for this stage, have one person attach the brackets to the inner groove of the posts, which will determine where the panels will sit. It is best to fasten the brackets prior to installing the posts, so you can ensure exact measurements from the top of the post and create an even wall height.
- For flush capping, the brackets should also be fastened around 3mm more than the total panel height. So, if the total height of your panels is 1800mm (1.8m), your brackets should be fastened at 1803mm.
- For external capping, allow 23mm more than the total panel height. Therefore, if the total height of your panels is 1800mm (1.8m), your brackets should be fastened at 1823mm.
The other person can then prepare your concrete as per the instructions on the package. Avoid throwing a bag of ‘rapid set’ down a hole and adding water in situ. Preferably, mix the concrete in a wheelbarrow prior to pouring down the hole, as this will achieve a greater concrete strength.
Once the concrete is ready, have one person holding the post whilst using spirit levels to ensure it’s exactly vertical. The other person can then pour the concrete into the hole all around the post.
Different concrete mixes will set at different times; see the concrete manufacturer’s instructions for more details. Smaller jobs using rapid set concrete may even allow the panels to be installed on the same day. However, best practice is to let it cure overnight, where possible, so this might be a good time to hang up the work gloves for the day.
After they’ve set, you may also want to use your spirit level to double check that none of the posts have shifted angles before inserting your panels.
3. Insert panels and capping
This is where your wall or fence is really going to take shape!
First, place the capping channel onto the bottom of your first panel. Next, with two sets of hands, slide the panel down through the post until it rests against the brackets. For multiple panels, a joining strip will need to be placed between each panel. Once all the panels are in, you can then install the the top wall capping, followed by the post tops.
4. Finish your DIY Modular Wall or Fence
