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.

Complaints: 

This is very common in the Western US . We receive very little rain fall. This allows the dust, dirt and oil to build up on the parking lots and roads. That dirt and oil is carried by the tires and becomes very noticeable on a fresh white or yellow stripe. Remember that the striping is engineered to delineate, not to be driven over by cars and trucks cutting across the empty parking lots. The paint industry has finally developed a semi-gloss traffic paint that helps make this less noticeable. It however does not eliminate the tracking altogether. You will find that as time goes on the paint will resurface and stand out from the initial dirt and oil. To help reduce tracking please keep the lots swept and clean as possible.
