Frequently Asked Questions Q: Is landscape curbing permanent? A: The curbing we install is made of concrete. It is heavy, durable, and one continuous piece. This offers many benefits over most other edging materials. If you need to remove the curbing, simply have it cut or busted into smaller sections that can be disposed of. Q: What type of concrete is used? A: We use a mixture of Portland Type I cement, DOT triple-washed sand, water and fiber-mesh (for increased strength).Mixtures with integral color also include a product to help preserve the color of the finished curb. Q: Why does it look like it is in sections? A: What appears to be a break in the curb is actually a control/expansion joint. This joint penetrates the curb about 40% of the way through. The curb is still one continuous piece. The purpose of the joints is to allow for ground movement and expansion of the concrete due to outside temperatures. This technique is part of how we minimize the potential for the concrete to crack. If a crack does occur, it is more likely to stay contained within the joint and may not be noticeable. Q: What are my color choices? A: Coloring the curb has almost unlimited options. We will explain different approaches such as putting color in the concrete mix vs. applying color coats after the curb is laid. The look of your curb and your satisfaction is critical to us, and we specialize in helping you reach a quality color choice. Of course, yours is the final decision. Q: What do I do if the curbing cracks? A: Concrete can crack. However, we utilize techniques, materials and equipment that minimize the potential for cracking. Our curb extruder, the expansion joints and using reinforced fiber-mesh in our concrete mix help prevent cracking. But if visible cracking occurs, sections can be replaced and the curb will still be one continuous piece. Q: What if I get lighted curbing and the lights quit working? A: The lighting is a polycarbonate tube that snaps in and out of a groove in the curb. It is a series of pieces connected together, and therefore sections can be replaced without disrupting the entire run of lights.
