How do you know it's time for a new patio?
Most patio problems start small and get worse with every freeze. Catching them early can mean a smaller fix, or at least a better plan for the new slab.
Cracks running across the slab
Wide cracks that keep growing usually mean the base moved or joints were skipped. Water gets in, freezes and pries the pieces further apart each winter.
One corner sinking lower
A low corner or edge usually means the dirt underneath settled because the base was raked flat, not dug out and packed. It tends to keep dropping.
Water pooling after rain
Puddles that sit mean the slab lost its slope or never had one. Water freezes there, and a slab tipped toward the house sends it at your foundation.
Surface flaking or peeling
When thin layers pop off the top, often where ice melt was spread, that's scaling. Once the top goes, the rough concrete underneath wears faster every winter.
Dusty, chalky surface
A top that rubs off as powder usually goes back to pour day, a hot afternoon or a rushed finish. It won't harden later and keeps wearing down.
Heaved or tilted sections
Pieces pushed up or tipped after winter usually mean water got under the slab and froze. Each spring they can shift more and turn into tripping edges.
What goes into concrete patio construction
Monolith Anchorage Concrete Company builds concrete patios in Anchorage from the ground up, and most of the real work is under the slab. We dig out soft dirt and pack the subgrade, the ground the patio sits on, then set a slope that sends water away from your house. I settle reinforcement with you early, usually rebar or wire mesh, steel that holds the slab together if it cracks, and I ask whether you'll use ice melt on it, since both change what we pour. We pour early in the day, give it a broom finish, a brushed texture that grips when it's wet, and cut control joints, shallow grooves that give cracks a straight place to go. Then it cures, which is the wait while the concrete gains strength, and if that runs into cold nights we cover and protect the slab through its early days. Size, what has to come out first, reinforcement and how easy your yard is to reach set the price, and your written estimate gives you that number. The weather sets the pour date more than anything else. If money's tight, cut the fancy finish, not the base, because the base gets buried on day one and you can't fix it later without tearing the patio out.
A patio rarely stands alone. If you want a pattern or color in the concrete, stamped concrete gets decided before the pour, because it's pressed in while the surface is still soft. If the patio needs a path to the driveway or a door, we can pour a concrete sidewalk at the same time so the two meet at the same height.
What happens after you call about a patio in Anchorage?
Here's how a patio job runs, from your first call to the walk-through on the finished slab.
Call and set a visit
Call or send us a message. I come out, look at the yard, check where water runs and ask how you'll use it.
Get the estimate in writing
You get the estimate in writing, so you can read it over, compare it and ask me about anything unclear.
Permits, pour date, pour
Once you say go, we line up any permits and pick a pour date around the weather. I'd rather wait a week than pour into trouble.
Walk the patio together
When the forms come off and we've cleaned up, we walk the patio together. I'll tell you when it's ready for feet and furniture.

Patio questions we hear
These are the questions Anchorage homeowners ask before a patio pour. If yours isn't here, call or send a message and I'll answer it for your yard.
How much does a concrete patio cost in Anchorage?
A concrete patio in Anchorage usually costs about $7 to $15 per square foot. That's the going rate in the area, not our price, and it runs higher when an old patio has to be torn out, for a thicker slab, reinforcement, stamping, a stain or coating, or on a sloped, rocky or hard-to-reach yard where trees or dirt have to go. Your written estimate gives you the number for your job.
Can you pour concrete in cold weather in Anchorage?
Yes, concrete poured in cold weather still gets strong and durable if it's placed and protected properly. It counts as cold-weather work once the air drops to 40°F, or is expected to, while the fresh concrete is protected, and the colder it gets, the more protection it needs. That's why I pick pour dates carefully and sometimes tell people to wait.
How long does new concrete need protection from freezing?
Until it gains early strength, because a single freeze can damage fresh concrete before then. Most well-made mixes reach that point within 48 hours at 50°F, so the days right after the pour are the ones we plan cover for. If heaters run near a new slab, ask how the exhaust is kept off it, since carbon monoxide can leave a surface less than a day old dusty.
What is the best way to make a concrete patio hold up to freezing and ice melt?
Ask whether the mix has entrained air, tiny bubbles in the concrete that help it handle freezing and thawing and limit flaking from ice melt. Curing matters too, because surface flaking is the most common frost damage, it's tied to de-icing salt, and good curing helps prevent it. A patio that gets salted takes a harder beating than one that doesn't, which is why I ask about ice melt up front.
Do I need a permit for a concrete patio in Anchorage?
Ask the city before you plan around it, because inside Anchorage's Building Safety Service Area the building official issues permits to build, alter, repair or demolish a building or structure unless the work is exempt. The Municipality of Anchorage permit counter takes questions at 907-343-8301 or permitcounter@muni.org. If your patio needs a permit, we handle the paperwork where we're able and tell you plainly if any part has to come from you.
What goes under a concrete patio?
A packed base layer, and its main job is drainage. Pavement guidance says the layer under concrete mostly serves to drain water, and in northern climates where frost reaches deeper than the slab, a high water table causes frost heave, the ground pushing up as it freezes. Ask any contractor what goes under your patio and how it drains.
