Step 1. Plan And Measure

The first step in making a garden arch out of PVC is to plan and measure the arch. Decide on the size and shape of the arch and then use a measuring tape to measure out the PVC pipes needed for the project. Use a permanent marker to mark where you need to cut the pipes.

The height of the vertical pipes will depend on how tall you want your arch to be, plus add 10-12 inches (25-30.5 cm) for the part of the pipe that will be buried in the ground.

The length of the horizontal pipe will depend on how wide you want your arch to be. Basically, just make sure you can fit through!

It’s important to have a clear plan before you start cutting and connecting PVC pipes.

Pro Tip 1: Before taking any measurements, try out the PVC pipes and connectors to better understand how they fit together. This will ensure that you get accurate measurements and a properly fitting garden arch.

Pro Tip 2: Remember that part of the PVC pipe will go inside the connector, and the bend on the connector will add an inch to the length and width of the arch.

Step 2. Cut PVC Pipes To Size

With your plan and measurements in hand, it’s time to cut your PVC pipes to the marked length. You can use a reciprocating saw, PVC cutter, or hacksaw to cut the PVC pipes.

A reciprocating saw is a powerful tool that cuts through materials quickly and easily, making it a great choice for larger projects.

A PVC cutter is a handy tool that provides clean cuts when working with PVC pipes. It’s a simple and efficient way to get the job done without any mess or hassle.

A hacksaw can cut through PVC pipes, but it requires more effort and may not produce as clean of a cut as the other options. However, if you already have one at home, you don’t need to buy extra tools for PVC cutting.

Pro Tip: When cutting PVC pipes, try to make clean, straight cuts. But if they are not that straight, no need to worry! A couple of inches will be hidden inside the connectors anyway.

Step 3. Sand The Edges

After cutting the PVC pipes to the desired length, smooth the edges.

Using sandpaper, sand the cut ends until they are smooth. This will ensure the pipes fit snugly into the connectors and create a sturdy connection.

This simple step will save you time and energy when connecting all PVC pipes.

Step 4. Connect The Pipes

Using the PVC connectors, connect the vertical pipes to the horizontal pipe to form the arch. Use 90-degree elbows for the corners and T-shaped connectors for the middle of the horizontal pipe (if you have any).

To connect the PVC pipes, you need to apply a sufficient amount of PVC glue to the inside of each connector and the outside of the pipe. This creates a strong bond between the two parts. Then, slide the pipe into the connector and twist it slightly to ensure it’s secure.

Wipe off any excess glue with a cloth.

Step 5. Dig Holes

Once the arch is assembled, place it on the ground and mark the location of the holes. Then, it’s time to dig the holes where the arch legs will be placed.

Dig the holes deep enough to be at least 10-12 inches (25-30.5 cm) below the soil line. This will ensure the arch is stable and won’t tip over in windy conditions.

Step 6. Secure The Arch

Once you have dug the holes for your garden arch, it’s time to secure it in place. There are two options: either the PVC arch legs can go directly into the ground or, if you have soft soil, pour concrete to secure the bottom of the arch.

If you place the arch legs directly into the ground, position the arch in the holes you dug and fill them with soil, tamping it down to make it as firm as possible. This will keep the arch in place and provide stability.

On the other hand, if you have soft soil or want to ensure maximum stability for your garden arch, pouring concrete is the way to go. Here’s how:

  1. Prepare the area: Clear away any debris or vegetation around the holes and level the ground. Then, place the arch in position.
  2. Mix the concrete: Mix the concrete according to the instructions on the bag.
  3. Pour the concrete: Slowly pour the concrete into the holes around the arch legs. Fill them at least halfway. Use a level to check that the arch is straight and adjust if needed.
  4. Allow the concrete to dry: Let the concrete dry completely before continuing with any further work on the arch.
  5. Fill the hole: Once the concrete is dry, fill the remaining space in the hole with soil or mulch. This will give your garden arch a finished and polished look.

Securing the arch in place can ensure it remains stable and safe for your plants and anyone walking under it.

Pro Tip: To make the arch even more secure, you can use metal stakes to anchor the arch legs to the ground. Simply drive the stakes into the ground before pouring concrete on either side of the arch and secure them to the arch legs.

Step 7. Decorate The Arch

Now that your garden arch is in place, it’s time to decorate it. Adding flowers, vines, or other plants to the arch creates a beautiful and natural look. You can also add lights or ribbons for a festive touch. Let your inner creativity shine!

Choose plants that complement the overall style of your garden and the arch itself. Climbing plants like roses, wisteria, or jasmine can create a romantic look. At the same time, ivy or other green vines can add a more natural feel.

To attach plants to the garden arch, use plant or twist ties to secure them to the PVC pipes. Be careful not to tie them too tightly to prevent damaging the plants. Also, make sure to provide enough space between the plants to allow for growth and prevent overcrowding.

If you want to add lights to your garden arch, choose weather-resistant options suitable for outdoor use. You can wrap them around the arch or hang them from the horizontal pipe.

Finally, don’t forget about the ground around the arch. Add mulch, gravel, or stepping stones to create a beautiful pathway leading up to the archway.

With some creativity and effort, your PVC garden arch can become a stunning focal point in your outdoor space.

Factors such as exposure to sunlight, chemicals, and extreme temperatures can affect the lifespan of the PVC pipe.

Is PVC Pipe Bendable?

Yes, PVC pipe is bendable. It can be easily bent and shaped using a heat gun or special bending tools designed specifically for PVC pipes.

However, the extent to which a PVC pipe can be bent depends on the thickness and diameter of the pipe. Excessive bending or twisting can weaken the pipe and affect its structural integrity.

Does Heating PVC Pipe Weaken It?

Yes, heating PVC pipe can weaken it. Heat can cause the plastic to become more pliable, which can lead to warping or deformation of the pipe.

Exposing PVC pipes to high temperatures can cause them to break down and degrade over time, ultimately leading to the pipe’s failure.

Do You Need To Use Glue When Assembling Your Garden Arches?

When assembling garden arches, you can use either glue or screws, or a combination of both.

Glue is a good option for creating a strong, permanent bond between PVC pipes. At the same time, screws can provide additional support and stability.

Can I Use PVC Pipe For A Trellis?

Yes, PVC pipe can be used for a trellis. It is a versatile material that can be easily shaped and cut into any trellis design.

PVC pipe is also durable and weather-resistant, making it a good outdoor option.

As PVC is lighter than other materials used in the garden, the trellis needs to be firmly secured to the ground or to a support structure to ensure stability.

Final Words

Building a garden arch out of PVC is a great way to add beauty and elegance to your garden without breaking the bank.

Following these simple steps, you can create a stunning garden arch that will last years. So why not give it a try and see how easy it is to create a beautiful outdoor structure using PVC?
