There is a lot more to concrete curbing than meets the eye. To ensure the right mix is applied on the high wear and high-stress point areas, and to get the right shape and finish to suit its purpose and aesthetic appeal, it’s important to have the right concrete curbing machine for the job.
Differences in Curb Wall Construction
The concrete curbing machine selected will primarily need to fulfil the requirements of the curb wall construction.
Curb walls for different purpose areas can have vastly different designs. Design of curb wall construction will depend on the primary purpose, which may be purely aesthetic, for traffic separation or for traffic access, or to assist in collecting and directing the runoff from storm water and debris.
Below common options for curb wall construction are explained.
Barrier curbs: A barrier curb may be a straight 90-degree square curb, or typically slightly angled at the top, or curved for aesthetics. These curbs are standard where traffic separation or boundaries are needed.
Mountable curb: A slope-faced or mountable curb, is used when access by traffic is needed, a common example is driveway entrance curbs.
Curved Curb: Curved curbs can come in a variety of shapes, primarily for aesthetic appeal, but the curve may also be for mountable or stormwater reasons.
Stormwater Curb: A stormwater curb will provide a channel for rainwater runoff to flow into to drainage points.
Within these four basic groups, there are still a variety of sizes, shapes, and looks.
Most types of mid-range curbing machine will allow fitting of different shaped curbing forms to cater for a range of different curb wall construction types.
Not all concrete curbing machines are equal!
There are a variety of sizes and construction types for curbing machines.
A curbing machine could be a simple manually powered machine, most industrial machines are gas powered, and some, less commonly, may be electric.
A machine for small landscaping uses may be easily loaded in the back of a pick-up, or even a car boot, by one person. For small areas, manually powered machines may be sufficient. Inexpensive curbing machines for simple applications may have a fixed form, the inflexibility of the output is balanced by their simplicity and cost.
Large machines for roadside use may need a special purpose trailer or a truck for transport. The higher end machines will have far more versatility, advanced design, automation, and much higher output speed.
A smaller machine is designed for hand-mixed concrete, whereas a larger machine will be designed to accommodate a concrete truck with pre-mix.
A commercial curbing machine can have as many as 1200 forms, with extrusion speeds of up to 15ft per minute.
Ease of Use Curbing Machines
Older types of curbing machine sometimes required specialist training, while newer machines with complex automated design, the operation requires less skill.
Early curbing machines were simple ram type machines; however, they had many faults which required special techniques for effective application, and they had a great deal of wastage. Later machines include features such as the orbital ram, auger, and twin auger, with vibrating or self-feeding hoppers, to solve many of the early design faults.
Regardless of skill needed, for quality control, it is still vital that the concrete curb construction company has experience in the correct concrete application mix and use of any curbing machine type.
Choosing the Right Curbing Machine
Whichever type of curbing machine you choose, the important thing is that it suits the application. Decide what you need to do first, whether you need only one type of curb, or a range of curb forms, small or large jobs, then look for the type of curbing machine or concrete curb construction company that will suit the application needs.
Whether it is for roadside curbs or special purpose landscape curbing, a reliable concrete curb construction company will assist you in finding a curbing machine that meets your specific application requirements.
