Deicers, complaints of concrete damage

While it finally looks like spring is here to stay, the results of a long, hard winter on our homes and yards are now becoming apparent. Much of this damage is simply a result of our region’s annual battle with Mother Nature, but there are other damages we self inflict through improper maintenance.

One common complaint we receive each spring from homeowners is that their exterior concrete surfaces on walkways, sidewalks and driveways have begun to flake, peel or both. Unfortunately, much of this damage could have been avoided with the avoidance or proper use of chemical deicers. Even though the next winter season is now months away, here are some recommendations from the National Ready Mixed Concrete Association and local concrete purveyors on how to avoid concrete flaking and peeling.

Select the Right Deicer

As avoidance of a deicer agent is not a preferred option in our climate, selecting the proper deicer is essential. There is great confusion among homeowners on which deicers to use. While they should all be used sparingly, avoid deicers that contain ammonium sulfate or ammonium nitrate. Both are chemically aggressive and destroy concrete surfaces.

Use Sand Instead of Deicer on New Homes

Concrete is very susceptible to flaking and peeling during the first winter as it has not completely cured. It is ideal to use clean sand for traction until the concrete has been through a full freeze-and-thaw cycle.

Use Deicer Moderately

Many people feel that since a little deicer does a good job, then a lot should do a better job. It is very important that the deicing agent be spread according to the manufacturer’s instruction.

Remove Excess Slush and Deicer

After applying deicer, it is important to let the melting action of the deicer break the bond between the ice and pavement then immediately remove the remaining ice and snow. Most concrete damage is actually not a result of the deicer but from the frequent freeze thaw cycles of winter. If not fully removed, the slush and water soaks down into the pores of the concrete and expands when temperatures drop below freezing.

Seal Your Concrete

To decrease the risk of water penetration, it is important to apply a concrete sealant. Use a commercially available silane or siloxane-based breathable concrete sealer or water repellant specifically designed for use on concrete slabs. This will help prevent the newly placed concrete from becoming saturated with water prior to freeze-and-thaw cycles during the winter months.
