Bad Curb

How to tell if curb is good or bad

Curbing is a handmade product. Installation takes some skill with a large variety of factors from concept through completion

Just drawing a good line on the ground takes some skill, let alone actual design considerations, quality of the ingredients, the mixing ratios used, equipment limitations, dealing with rough or unusual ground conditions, crew inexperience, materials, weather, etc!

Curbing should be installed so it flows smoothly without sudden side to side “kinks”  in the lines or “bumps” up and down. Admittedly, the ground can be difficult sometimes, and you might see some wiggles in anyone’s work. But this should be minimal.

It should function as a mowing edge. Curbs installed too steeply or too high above the ground are useless as mower strips. You need to mow beside them and later go all along with the seedeater to trim the grass. I just do not understand the rationale behind that kind of curbing. Maybe people think it “shows nicely” but in reality it can just look too bulky.
