Features Warranties for Concrete Driveways

In 1991, a group of concrete contractors and ready mix producers in Kansas City, Mo., began to offer warranties on concrete driveways as a value-added product to homeowners.

Started in 1994, the program encourages residential concrete contractors to use a potent marketing tool: warranties for driveways. Those who have embraced the program speak enthus- iastically about the positive effect it has on quality and profits. Read more

Other advantages of these systems when compared to conventional forming methods include faster wall erection (forms are easy to erect and do not require stripping), and better concrete curing and a longer construction season (the foam insulates the concrete).
