Curb and Gutter
A common question we get a lot is can your machine extrude a curb and gutter? The short answer is Yes it can. However, there are a few obstacles. One is the grade. None of our machines have the ability to change the grade. So any imperfections in your grade will result in your curb and gutter having those same imperfections. Two, if you are doing a curb and gutter and the gutter is 12″ (CFD-1717), 14″ or 16″ wide, then any machine (550, 650, 850 or 900) with 8” augers will work. However, if your gutter is 18” now you have 2 choices. If you decide to do your curb and gutter project with a machine with a single 8″ auger in it, you may run into a situation where the machine would fill enough of the curb form to propel itself back, before it fills the entire form. Thus you may have to do some hand work to fill it in. Our Curb and Gutter (this machine has dual auger shafts) machine is designed to fill an 18″ or 24″ curb and gutter. Any 24″ curb and gutter would need to be done with our Curb and Gutter machine. Finally, plan to do some hand troweling once the curb and gutter has been extruded.
Barn Curb is a type of curbing that is installed in the construction of a new dairy barn. Barn Curb has to be able to with stand being run into by a skid steer. CFD-1650 is a typical barn curb design. Some applications for barn curb require going over a pin or extruding rebar into the curb. Barn Curb is typically done with an MC 550, 650 or 850 and would require 8″ augers. If you need to extrude a barn curb, please contact us to discuss your project.
Trench Curb is a type of curbing where a trench is excavated, the trench is filled with concrete and the machine extrudes a curb over top of the trench while the concrete is still green. This is popular style of curbing in Florida and it is a common way to do a Florida D curb (CFD-906).
Curbing Over Pins
Another frequent question we get is can I go over a pin with your machine? The short answer is yes, however a few things are needed in order for this to work. One, the pins must be no more than a 1/2″ from center. Two, we need to have 5″ from the top of the pin to the top of the curb form. So, with a curb form that is 7″ tall, the tallest pin that you could extrude over would be 2″. Keep in mind if you want to run rebar on top of the pin, we still need to have 5″ from the top of the rebar to the top of the curb form. So now with a 7″ curb form, your pin may only be 1 and 3/4″ to allow for a 1/4″ diameter rebar on top of the pin.
