Q: How long are those pieces and where do I buy them?
A: "They" are not pieces or sections. The breaks you see approximately every 3' are expansion/control joints. The curbing is installed on each job site. Please refer to the Process page.
Q: How deep do you dig and how deep is the footing?
A: We dig about 2 ½ inches deep by 10 inches wide. This can be done without disturbing your existing planters. There is no footer as the curb is concrete and is its own footing. Please refer to the Process page.
Q: What about frost and ground movement?
A: The benefit of our concrete curbing is that is a continuous piece of concrete. Individual blocks or bricks will shift over time and in the winter. Our curb is fibermesh reinforced which is designed to take the place of rebar or steel and adds strength to the curb. We place control/expansion joints every 3 feet and are cut about 40% into the curb. This is designed to control the cracking of the curb during shifting periods and colder months. If the curb should crack, it should crack in the expansion joint and not be noticeable.
Q: Is the color painted or stained on the curb?
A: All of the colors are iron oxide pigments that are mixed into the concrete during the mixing process. The color will not flake off or disappear over time. You may experience a little fading, but this is normal in any outdoor color application. A sealer can aid in the lifetime of the color, we recommend sealing every year.
Q: What kind of base is placed under the curb?
A: We make sure the base under the curb is compacted and level. Sometimes we will put a small layer of sand under the curb to ensure the level of the curb. If the curb should settle a little, the expansion joints should control the cracking.
Q: Will the curbing crack?
A: We experience very little cracking however concrete will crack. We take every precaution to limit the cracking and try to control it with expansion joints. If a crack occurs outside of the joint, we will be happy to repair your curbing.
