How to Make a Simple PVC Pipe Arch Form

The folks at have devised a simple, but effective way of creating an arch form for making arches with earthbags. They have tested the concept with both bags of rice hulls and bags of heavier soil, and it seems to work well with either. They have published a step-by-step guide to making and assembling the form, which is primarily made with small diameter PVC pipe,  and I have adapted what they show for readers of here.

There are several advantages to this idea:  the materials are inexpensive and readily available; it can be fabricated and assembled quickly; it can be reused; it does not require a base to rest on; and it is easy to release once the arch is built.
