How to Protect Your Concrete Through a Missouri Winter

Southwest Missouri winters are hard on concrete. They're not always brutal, but temperatures bounce above and below freezing again and again. Every time water soaks into the surface and freezes, it expands. Over time, that can cause flaking and pitting, known as spalling.

The good news is that a little care goes a long way.

1. Seal before winter

A quality penetrating sealer keeps water and salt from soaking into the surface. Most driveways, patios and walkways benefit from sealing every few years, and decorative or stamped concrete should be resealed every 2–3 years. Fall is a great time to do it.

2. Skip the rock salt

Rock salt and some chemical de-icers are tough on concrete, especially during the first winter after it's poured. Instead:

• Use sand or kitty litter for traction
• If you need an ice melt, choose one labeled safe for concrete
• Shovel early so snow doesn't get packed into ice

3. Keep water moving away

Standing water is concrete's enemy in winter. Make sure downspouts drain away from your driveway and walks, and keep an eye out for low spots where water pools.

4. Fill cracks before they grow

Small cracks let water get underneath your slab, where freezing can make them worse. Seal small cracks with a concrete crack filler before winter sets in.

5. Be careful with plows and shovels

Metal blades can chip edges and scrape off sealer. A plastic shovel blade, or a plow with a rubber edge, is gentler on your concrete.

When repair isn't enough

If your driveway or walk is badly cracked, sinking or crumbling, it may be time for replacement. A new slab with proper base prep and the right mix holds up much better to freeze-thaw cycles. We're happy to take a look and let you know honestly whether it's worth repairing.
