What Causes Pavers to Fail in Michigan — And How We Prevent It

If you've seen a patio or walkway in Metro Detroit that's cracked, shifted, or sunken after just a few winters, it wasn't bad luck. It was a base problem.

Michigan's climate is uniquely hard on hardscape. We experience dozens of freeze-thaw cycles every year — temperatures dropping below freezing at night and rising above it during the day. Water trapped beneath a paver system expands when it freezes, and that expansion has to go somewhere. If the base isn't engineered to handle it, the surface above it fails.

The most common causes of paver failure in Michigan

Insufficient base depth — A proper base in Michigan requires 6 to 8 inches of compacted gravel. Many contractors use far less to save time and material costs. The result shows up within two or three winters.

Poor drainage planning — Water that has nowhere to go pools beneath the surface and accelerates freeze-thaw damage. Drainage must be considered before the first stone is placed.

Inadequate compaction — Gravel base material must be compacted in layers. Dumping it in and running a plate compactor over it once is not the same thing.

Wrong sand layer — The bedding sand layer beneath pavers must be the correct type and depth. Too much sand creates instability. The wrong type retains water.

No edge restraints — Without proper edge restraints, pavers migrate outward over time. This is especially pronounced through freeze-thaw cycles.

How we build hardscape to last

At Home & Hardscape, every installation begins below the surface. We excavate to the correct depth for Michigan conditions, install a properly graded and compacted aggregate base, plan drainage into the design from the beginning, and use edge restraints on every project. The surface work — the part you see — is the last thing we think about, because everything underneath has to be right first.

The bottom line

A paver patio is a long-term investment. The difference between one that lasts 20 years and one that needs repair in three is almost entirely in the base preparation. Ask any contractor you're considering exactly how they build their base — and if they can't give you a detailed answer, keep looking.
