The CornerStone segmental wall system was invented by a hardscape contractor so it is very user friendly. Our wall contractor customers enjoy the flexibility and versatility of the product and typically have faster than normal production rates vs. other systems that they use. Even though CornerStone was invented over a decade later than some of the other wall systems on the market, their team has taken great strides over the past few years to catch up and be on par with the other wall products. They are always responsive and provide me with what I need in a timely manner- whether it’s a CAD detail, a marketing piece or engineering data. I am happy to be promoting and selling the CornerStone system.
