A trick to laying out near perfect curved bedlines.


If you have ever tried to mark off long curved lines by hand, you probably know that it is not easy. What seems like a nice curved line while marking ends up with it having strange bumps and not so smooth curves. A trick to laying out very nice curves is to use several long lengths of 3/4 inch pvc pipe. I prefer using schedule 20 irrigation pipe, as it is already in 20 foot lengths and one end of each

  • Everyone is correct in that garden hose does work to help lay out a bedline. The photo shown above is to illustrate another way to lay out near perfect curved lines. The pvc we use for this is 3/4" thin wall PVC. It is a schedule 20 pvc, which is used for irrigation lines. The thin wall allows it to be very flexible. The reason we use pipe versus hose is because when you take a long piece of pipe and flex it, it will bend into a beautiful curve. Since this pipe comes in 20 foot lengths, it is difficult to transport, but at about $3 per 20 foot stick, it could almost be a disposable item if the project justifies it. You could have 60 feet of pipe to bend for less than $10. Here is an example, if you wanted to mark off an exact circle in the ground, you can either place a stake in the center and tie a string at the desired radius, then mark the circle by walking around with the fixed length string. A long piece of PVC pipe can be looped into a circle, and it will be in a near perfect circle that can be laid on the ground. and marked. A garden hose provides something to follow, but it does not provide the near perfect curve. We mainly use PVC pipe to mark curves in our hardscape projects. It allows us to mark a nearly perfect curve and then saw cut the patio and walkway curves.

    I see what you mean southern...a garden hose could make a sidewalk a little wind-ey whereas the pvc would be smoother and more accurate for walking '')
