Harsh winter weather is the bane of every home improvement project, but it’s especially frustrating for those planning to work with concrete. Concrete can be difficult enough to work with under perfect conditions; when the temperature dips below freezing and snow starts falling, you’re in for a rough time.
If you’re wondering how to go about constructing an outdoor patio or driveway during the winter months in Waco, TX, there are some essential things that you need to know before starting on your concrete project.
1. Frost Heaving
The ground will likely shift during subfreezing temperatures because water expands as it freezes. If the ground beneath your concrete is shifting, it can cause large cracks and other structural damage to your patio or driveway.
Frost heaving should be expected during winter, so plan for additional expansion joints in order to prevent severe problems with how well your new outdoor living space holds up over time.
2. Weather Conditions
Other weather conditions can also hinder your ability to work with concrete in winter properly.
You should try and avoid working outside when there is a lot of wind or rain because these harsh weather elements could affect the quality of your finished product.
In addition, you will need more time for projects during this season, so plan accordingly by adding additional time for your project during the winter.
3. Preparation
When working with concrete outside in the winter, you will need to take extra precautions when getting prepared for your project.
You should double-check that all of your tools are properly stored away, so they do not get damaged by snow or rain due to being left out during this season.
In addition, be sure to have a shovel and broom nearby to clear any excess debris from your project area, so you do not slip on ice or snow.
4. Pouring
When pouring concrete in the winter, you will want to ensure it is done at a slow and steady pace.
If poured too quickly, then there is a higher chance of air pockets forming, which can lead to your material cracking once it has thoroughly dried. You should be aware that cold temperatures could also lead to the material getting too stiff and dry, which can cause it not to adhere together effectively.
5. Longer Curing Time
Concrete takes a significantly longer time to cure when the temperature drops below 45 degrees Fahrenheit. This can be frustrating if you’re trying to complete your project as quickly as possible, but it’s also crucial for ensuring that your concrete will last through winter and beyond.

Cold-weather steps that protect a pour
Concrete can be poured in winter, but new concrete must not freeze in its first few days. Here’s what a careful contractor does:
- Never pour on frozen ground or frost. The subgrade has to be thawed and firm, or the slab will settle as it thaws.
- Adjust the mix. Suppliers can use warm water and set-accelerating admixtures. Where there is steel reinforcement, non-chloride accelerators are the safer choice.
- Cover it. Insulated curing blankets hold in the heat the concrete makes as it hardens.
- Watch the forecast for several days, not just pour day. In Texas, a norther can drop temperatures fast overnight.
- Use air-entrained concrete for outdoor flatwork. It resists freeze-thaw damage over the life of the slab.
Winter rain and clay soil
Around Waco, Temple and south DFW, winter rain is often a bigger problem than cold. Blackland clay swells when it is soaked, and a slab poured on saturated clay can crack or heave as the ground dries out. Good base preparation, drainage that sends water away from the slab, and waiting for the ground to dry after heavy rain all help.
When can you use new concrete in winter?
- Foot traffic: usually after a day or two in mild weather, longer when it’s cold.
- Cars: about 7 days in normal conditions. Cold weather slows strength gain, so plan for more time.
- Heavy trucks: wait longer. Concrete reaches its design strength around 28 days in normal conditions.
We pour driveways, sidewalks, pads and parking areas through our concrete paving service, including work for commercial properties and HOAs and subdivisions.

Frequently asked questions
How cold is too cold to pour concrete?
There isn’t one cutoff. Once air temperatures fall below about 40°F, cold-weather precautions are standard. Below freezing, pours need full protection or should be rescheduled.
Can I use salt on new concrete?
Avoid deicing salts on new concrete, especially the first winter. Use sand for traction instead.
Is winter or summer harder on concrete in Texas?
Both have challenges. Summer heat and wind make concrete set and dry too fast, so crews pour early and focus on curing. Winter slows setting and brings freeze risk.
A freeze is forecast the night after my pour. What happens?
With blankets and the right mix, a pour can often go ahead. If a hard freeze is coming and the slab can’t be protected, it’s usually better to reschedule.
Will winter concrete look different?
It can. Cold, damp curing can change the shade slightly, especially with colored concrete. Even curing and protection keep the color more uniform.
