Common Types of Concrete Curbing

• Extruded: This is a continuous glue on curb that you will find in most parking lots. It has very little structural value and is engineered to hold in and delineate landscaping.
• Cast-in-Place (CIP) and Curb and Gutter: These are both formed and poured in most cases and sit below the surface approx. 18” deep. These have a much better structural feature because of the large mass under the ground. These curbs can also have rebar placed when they are poured to help make them structurally durable.
• Parking Bumpers: These are generally 6’ long by approx. 6” tall precasted curbs with 2 pieces of rebar placed in them for structural integrity per MAG spec. You can also find a 5 sided low profile bumper that is also 6’ long but 5” tall and wider to help keep them from being moved. They are both secured into the asphalt or concrete with rebar pins. Please make sure you let the contractor know if it is concrete or asphalt. The concrete must be drilled to allow the rebar to penetrate.

• For retail centers, it is not unusual to restripe the parking lot every year or as needed.
• For industrial and office, every other year is more common.
• Red curb painting should be done every 6 - 12mnths depending on the level of maintenance kept at the site.
