How Berks County’s Documented Karst Geology Affects Shillington

Berks County has its own PA Geological Survey karst-feature inventory, the same documentation standard applied to Lancaster and Chester counties — limestone bedrock underlies significant parts of the county. 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.

How often should a driveway be sealcoated?
Every 2-3 years is typical for most driveways, though heavier use or harsher winters can shorten that interval.

How can I tell if my driveway needs full replacement or just a patch?
Isolated cracks and small potholes can often be patched. Widespread alligator cracking or a driveway that flexes underfoot usually means the base has failed and needs full replacement.

Does sealcoating actually make a difference?
Yes — it protects against water penetration and UV damage, which are the two biggest drivers of freeze-thaw cracking. Most driveways benefit from resealing every 2-3 years.
