Belgium Block (Cobblestone) Curbing - We install curbing that will never move. As this photograph illustrates, a wooden form is constructed, then a steel reinforcement rod is secured in the bottom third of the form. The form then gets filled with super strength concrete and the cobblestones are positioned. After the concrete sets, all the joints are completely filled and sealed. These carefully planed steps protect the curbing from deterioration. Michael likes to boast- "If a snowplow hits my curbs, the truck's frame will bend before the curb moves!"
