Concrete driveways

Concrete grade. Concrete grade is defined by the strength of the concrete and is measured in pounds per square inch (psi).  In general, the higher the psi grade, the more weight it can handle, the more durable it will be, and the better it will hold up when pressure washed.  Concrete used in driveways is usually 3,000 or 4,000 psi.  The 4,000 psi grade concrete is slightly more expensive than the 3,000 psi grade concrete.  However, this price difference is small when compared to the total cost of driveway replacement.

Color variation. Unfortunately, due to variation in the color of the raw materials that make up concrete, colors will vary between batches of concrete.  Color variation is usually not a problem in a complete replacement job, since all of the concrete usually comes from the same batch.  However, when adding to or replacing a section of an existing driveway, you should expect color variation.
