What in the world is extruded concrete curbing?

We get this question a lot! Extruded concrete curb is a mouthful. In simple terms, it is bed edging formed by compacting concrete through a special machine. It reminds me of watching "Cake Boss" or the cake decorating center at WalMart. The concrete comes out of the machine much like frosting comes out of a cake decorating tool. It is continuous and it is shaped by the form at the end of the tube.

The concrete you see in the above video has been dyed black (as per the Client's request) in the mixing process. The extruding machine compacts the concrete to a strength of 3000 psi when cured.

In this video you see the troweling and finishing process. Our crew uses hand tools to complete the fine details such as corners, driveway tapers, and run completions. We also use these tools to insure a professional and clean finish to the curbing.

After the curb has its finished edge, we apply a custom stamp or texture. In this case, the customer selected a cobblestone texture. We can apply an accent color in this stage of the installation process, but since the Client selected black curb to match the house accents (i.e. shutters, facade accents, driveway customization) an accent color could not be used.

Once the customization process is complete, Patriot Curbing places control joints at crucial points in the curb. Control joints allow for the expansion and contraction of the concrete in the elements. These are used to insure any cracking occurs within the joint and not across the face of the curb.
