Mower Style This style is very popular because it is installed to both accommodate a lawn mower wheel and at the same time retain gardening materials because of it's higher back side. It also has great curb appeal because it sets off the landscaping with a picture frame type of look.
Synthetic Turf Style The synthetic turf style became popular around 2010 because it can be stamped and textured or done in regular gray concrete as can the curb style. But, unlike the curb style, it has the unique ability to also hold in gardening materials because the back of the curb is higher than the front. The front side of the curb is generally set a ground level to accommodate lawn mower wheels. This style also shows off any texturing or stamping that may be applied. And it is also the perfect compliment to a synthetic turf and hence the name.
Curb Style 4X6 The curb style is generally set at ground level for lawn mowing. It is very popular in commercial lawn settings because it handles larger mower wheels and has a more massive look. It can be installed as regular gray concrete or it can be stamped and textured. Because it is set at ground level it is not as easily seen from the street and therefore leaves a groomed look without seeing as much concrete edging
Curb Style 6X6 This style can be used like the regular curb style or it can be used as a retainer. The 6X6 is sometimes the spec that is used by commercial architects and it is simply placed deeper in the ground. Other applications may include retention of gravel, gardening materials or other driveway or walkway situations.
