Caring for New Concrete Through Its First Year
The first winter matters most. Cure time, de-icers, sealing, and what to keep off a fresh slab.
New concrete is at its most vulnerable in its first year, and most of what goes wrong in that window is preventable with information you should have been given at handoff.
How do I take care of new concrete?
Respect the cure windows before foot traffic and before vehicles, keep heavy loads off it entirely, go easy on de-icers through the first winter, shovel rather than scrape, and seal on the interval appropriate to your finish. New concrete is at its most vulnerable in its first year and most of what goes wrong in that window is preventable.
Cure time is not dry time
Concrete looks finished long before it is. Strength develops over time, and putting weight on a slab too early is one of the more common ways new work gets damaged. Your scope of work includes the specific windows for foot traffic and for vehicles, and they are different numbers. Waiting the extra days is a genuinely better trade than the alternative.
- Cure time and dry time are different things. Concrete looks finished long before it is.
- Foot traffic and vehicle traffic have two different waiting periods.
- The first winter matters most. New concrete is meaningfully more vulnerable to de-icers than cured concrete.
- Fertilizer used as an ice melt is a common and damaging mistake.
- Tell your snow removal service there is new concrete and where the edges are.
Keep the heavy things off
Vehicles, dumpsters, equipment, and loaded trailers all belong off a new slab until the cure window has passed. This includes the corner of the driveway where someone parks for five minutes.
The first winter and de-icing salt
New concrete is meaningfully more vulnerable to de-icers than cured concrete, and the first winter is the one that matters most. Surface scaling that starts in year one usually traces back to aggressive de-icer use on a fresh slab. We give specific guidance on what to use and what to avoid based on when your slab was poured.
Shoveling and plows
Shovel rather than scrape where you can, and be aware that a plow blade catching an edge or a joint does real damage. If a service plows your drive, tell them there is new concrete.
| Window | What to do | What to avoid |
|---|---|---|
| First days | Follow the foot traffic window in your scope | Any vehicle weight, furniture, dumpsters |
| First weeks | Follow the vehicle window before parking on it | Loaded trailers, equipment, sharp point loads |
| First season | Keep it clean, watch how water drains | Aggressive pressure washing of the surface |
| First winter | Shovel early and often, use sand for traction | Heavy de-icer use, fertilizer as ice melt, plow blades catching edges |
| Ongoing | Seal on the interval for your finish | Letting a colour or stamped surface go unsealed for years |
Your written scope of work carries the specific cure windows for your slab. They vary with conditions.
Sealing
Sealing intervals depend on the finish. A plain broom surface, a stamped surface with a color layer, and an exposed aggregate surface all want different schedules, and the stamped one wants the most attention. Sealing guidance for the specific finish you chose is part of the handoff rather than something you have to go looking for.
What is normal and what is not
Fine surface hairlines and slight color variation are normal. A crack that is widening, a section that is settling relative to its neighbors, or water pooling where it did not before are worth a call. Knowing the difference saves you worry in one direction and time in the other.
Frequently asked questions
How long before I can walk on new concrete?
There is a specific window in your scope of work rather than a universal number, because it depends on conditions at the pour. It is always shorter than the window for vehicles.
How long before I can park on a new driveway?
Longer than for foot traffic, and putting vehicle weight on a slab too early is one of the more common ways new work gets damaged. Waiting the extra days is a genuinely better trade than the alternative.
What de-icer is safe on new concrete?
Mechanical removal first is the honest answer. Shovel early so snow never compacts into ice, and use sand for traction. Where a de-icer is genuinely needed, use it sparingly and follow the guidance for the age of your slab. Avoid aggressive chemical products, and never use fertilizer as an ice melt.
When should new concrete be sealed?
It depends on the finish, and on the concrete having cured sufficiently first. Sealing guidance for the specific surface you chose is part of the handoff rather than an afterthought.
Are hairline cracks in new concrete a problem?
Fine surface hairlines and slight colour variation are normal. A crack that is widening, a section settling relative to its neighbours, or water pooling where it did not before are worth a call.
Every project starts with a site visit and a written, itemized scope of work sized by square footage. Base depth, compaction, slab thickness, reinforcement, joint layout, drainage work and permits each appear as their own line. No verbal ballparks, and no number quoted before anyone has seen the property.

Site visit first. Then a number you can hold us to.
We do not quote concrete over the phone, because a number given before anyone has seen the site is a number that changes.
You send the details
The form or a phone call, whichever you prefer. A team member follows up the same day.
We come look at it
Measurements, photos, drainage and grading assessment, and a conversation about finish options.
You get it in writing
A written, itemized scope of work sized by square footage. What is included, what is not, and what it costs.
