Concrete Care Tips for Houston-Area Homeowners This Winter

Winter in the Greater Houston area might not bring heavy snowfall, but it still poses real threats to your concrete surfaces. Freeze-thaw cycles, heavy rainfall, and ground movement from soil expansion can all cause cracking, spalling, and surface deterioration — especially on older concrete or surfaces that haven't been properly sealed.

At Katy Concrete Co, we see the results every spring: driveways that developed new cracks over winter, patios with surface pitting, and walkways that shifted from ground movement. The good news is that most of this damage is preventable with a little preparation.

1. Seal Your Concrete Before Cold Weather Sets In

Sealing is the single most effective thing you can do to protect concrete through the winter months. A quality concrete sealer creates a barrier that prevents water from penetrating the surface. When water seeps into unsealed concrete and then freezes, it expands — causing cracks from the inside out.

For driveways and patios in the Katy area, we recommend applying a penetrating silane-siloxane sealer every 2–3 years. If your concrete hasn't been sealed recently and temperatures are dropping, now is the time to act. Sealers need to be applied when temperatures are above 50°F, so don't wait until the coldest weeks.

2. Clear Standing Water and Fix Drainage Issues

Pooling water is concrete's enemy in winter. Areas where water collects — low spots in a driveway, corners of a patio, or anywhere grading directs water toward your slab — are at higher risk of freeze-thaw damage. Before winter, walk your property after a rain and identify where water sits for more than 30 minutes.

Simple fixes include regrading soil around the concrete edge or adding a channel drain. For persistent drainage issues, call us for a professional assessment — unaddressed drainage problems can also undermine the subbase and cause settling over time.

3. Address Existing Cracks Before They Grow

Small cracks that seem cosmetic in summer can become major structural problems after a winter of water infiltration and ground movement. Water enters hairline cracks, freezes, expands, and forces the crack wider. By spring, a 1/8-inch crack can become a 1/2-inch gap.

If you have cracks wider than 1/4 inch, or cracks that run across the full width of a slab, have them professionally evaluated before winter. Smaller cracks can often be filled with a polyurethane or epoxy crack filler available at hardware stores — but larger or structural cracks need professional repair.

4. Avoid De-Icing Salts on Concrete

If you do get a rare ice event in Katy, resist the temptation to pour rock salt or calcium chloride on your concrete. These chemicals chemically attack concrete, causing surface scaling and spalling that looks like the top layer is flaking off. The damage is permanent and requires resurfacing to fix.

Instead, use sand for traction, or a concrete-safe ice melt product labeled as chloride-free. Better yet, keep a bag of cat litter in the garage — it provides excellent traction without any chemical damage.

5. Keep Tree Roots in Check

Houston's mild winters mean trees stay active longer than in northern climates. Tree roots growing beneath concrete slabs are a year-round concern, but winter rain saturation makes soil conditions particularly favorable for root spread. If you have large trees near your driveway or walkways, watch for concrete lifting or cracking near the tree line.

Root barriers installed during a concrete repair or replacement project can prevent future damage. If you're planning a new concrete installation near trees, mention it to our team — we can recommend the best approach for your specific situation.

When to Call a Professional

DIY maintenance goes a long way, but some situations need professional attention. Call Katy Concrete Co if you notice:

• Cracks wider than 1/4 inch or growing rapidly
• Uneven slabs where one side is higher than the other (trip hazard)
• Concrete that sounds hollow when tapped (subbase failure)
• Widespread surface scaling or spalling
• Settling near your foundation

Catching these problems early almost always means a less expensive repair. Waiting until spring — when freeze-thaw cycles have done their worst — often means a full replacement instead of a patch.
