Why Manheim’s Limestone Karst Terrain Matters for Your Pavement

This sits on Lancaster County’s extensively documented karst limestone terrain (PA Geological Survey, Kochanov 1990) — the same carbonate bedrock that makes this farmland so fertile can also mean uneven subgrade settling that looks like ordinary cracking but is actually a base issue. Southeastern and central Pennsylvania see 25-35 freeze-thaw cycles per season, and PennDOT officially defines the Freeze/Thaw Period as February 15 through April 15 in Publication 23. Water gets into small cracks, freezes, expands about 9%, and widens the crack — repeat that thirty times a winter and a quarter-inch crack becomes a pothole by spring.

Can you pave over an existing gravel driveway?
Yes, but it requires proper grading and base compaction first — we assess the existing material before quoting a conversion.

Will I need township approval before paving?
If the work stays within your existing driveway footprint, usually not. New curb cuts or anything touching the road right-of-way typically requires it — we check this for you.

When can I park in my new driveway after paving?
Give it 2-3 days minimum before regular traffic. Avoid sharp turns or parking in the same spot repeatedly during the first 30 days while it fully cures.
