How can poor concrete laying or finishing contribute to de-icer damage?

When it comes to maintaining the integrity of concrete in winter, the quality of the original installation is everything. Improperly laid or finished concrete creates a perfect storm for damage, especially when exposed to any deicing product, even those labelled as safe. One of the most overlooked contributors to surface breakdown is poor construction technique. This includes inadequate air entrainment, incorrect curing methods, and insufficient moisture control during the setting process.

Air entrainment involves intentionally incorporating microscopic air bubbles into the concrete mix, which allows it to expand and contract during freeze-thaw cycles. Without this feature, the concrete becomes brittle and far more susceptible to spalling and surface deterioration—especially in climates with dramatic temperature fluctuations. In short: no matter how safe a deicer may be, it’s working against a fragile surface if the concrete was never prepared properly to begin with.
