Brock PaverBase panels vs traditional gravel base for ~270 sq ft patio in Albany, NY — worth it in freeze-thaw climate?
Planning a patio install, roughly 16 blocks x 21 blocks (each block ~15.5” x 7.5”), so about 270 sq ft total. Located in Albany, NY — so we get real winters with significant freeze-thaw cycles.
Deciding between:
1. Traditional 4-6” compacted gravel base + 1” sand bedding
2. Brock PaverBase plastic panels (seems popular now, claims to skip most of the gravel/excavation)
From what I’ve read, the panels save labor and excavation, but seem sensitive to how flat/compacted the ground underneath is, and some reviews mention settling issues over time. I’m specifically worried about frost heave given our winters — not sure if the panels handle freeze-thaw as well as a properly compacted gravel base.
For anyone in the Northeast / similar climate who’s used the panel system:
• How has it held up through a winter or two?
• Any frost heave or shifting issues?
• Did you still compact the soil thoroughly underneath, or skip that step?
• Would you do it again, or go back to traditional gravel?
Appreciate any real-world experience, especially from anyone dealing with NY/New England winters.
