Frequently Asked Questions

What drainage issues should I consider before installing pavers?
Before installing pavers, consider where water currently flows, whether the area has low spots that collect water, and whether the base can be graded to slope water away from buildings. Poor drainage can cause pooling, erosion, settling, weed growth, and freeze-thaw damage in colder climates. It’s also important to plan for downspouts, nearby landscaping, soil type, and whether drains or permeable paver options may be needed to manage runoff.
