The pour takes a day. Reaching full strength takes about a month. Santa Rosa weather allows concrete work in every month, with care in the rainy season and during late summer heat.
How long does it take to pour a driveway?
A typical driveway takes one to two days of preparation and one day to pour. Preparation covers breaking out the old slab, digging, compacting the rock base and setting forms and steel. Placing and finishing happen on a single day. Stamped work, pumping and awkward access add time, and permit inspections can add waiting days.
How long does concrete take to cure?
Concrete reaches most of its design strength in about 28 days. It is hard enough to walk on within a day or two and strong enough for cars in about a week. Curing is a chemical reaction that needs moisture, so in dry weather the slab is covered, sprayed with curing compound or kept damp for the first days.
When can I walk on new concrete?
You can walk on new concrete after about 24 to 48 hours. Keep dogs, bikes and patio furniture off for a few days longer, because the surface still marks easily.
How long before I can drive on new concrete?
Wait about 7 days before you drive on new concrete with a car or light pickup. Keep heavy vehicles such as moving trucks, motorhomes and loaded trailers off for about 28 days. For the first month, avoid parking in the same spot every day and avoid turning the wheels while standing still.
| Use | Typical wait |
|---|---|
| Foot traffic | 1 to 2 days |
| Cars and light trucks | About 7 days |
| Heavy vehicles | About 28 days |
| Sealing | About 28 days |
Can concrete be poured in the rain?
Concrete should not be poured in the rain when it is steady or heavy, because water on the surface weakens the top layer. Light drizzle can be managed with covers. Most of Santa Rosa's rain falls between November and March, and it comes in storms with dry days between them. We watch the forecast and move a pour by a day or two when needed.
Is it ever too hot to pour concrete?
It is rarely too hot to pour here if the day is planned for it. Once the temperature passes about 90 degrees, concrete sets quickly and the surface can dry and crack before finishing is done. Inland heat spells and dry winds in September and October are the risky times. We pour at first light, wet the base, and start curing straight away.
Can concrete be poured in cold or freezing weather?
Yes, and freezing weather is seldom an issue in Santa Rosa. A few winter nights dip to frost, mostly in the low parts of the plain and the valleys. Fresh concrete must not freeze in its first day or two, so on those nights it is covered with insulating blankets. Cool weather slows setting, which means a longer wait before use.
What is the best time of year to pour concrete?
The best time of year here is spring and early summer, roughly April to June, and again in October once the heat breaks. Days are mild and rain is unlikely. Summer works well with early starts. Winter works between storms, though wet ground can delay digging and base work.
Can I use salt or deicer on new concrete?
You should not need to. Ice on driveways is unusual in Santa Rosa, and deicer is hard on concrete, especially in its first year. If a rare frosty morning leaves a slick patch, use sand for grip. If you take the car up to the snow, rinse off road salt that drips onto a new driveway.
Does morning fog or damp air slow things down?
A little. Cool, damp mornings slow the set, so finishing runs later in the day. Damp air is actually kind to curing concrete because the surface does not dry out. The one job that needs dry conditions is sealing, which should wait for a dry slab and a dry night ahead.
