An Anchorage patio is used hard for four months and buried in snow for the rest. We plan the slope, the joint against the house and where roof snow lands before we talk about finishes. Tell us where the evening sun reaches your yard.
Summer in Anchorage is short and the daylight is long, so a patio gets used hard for about four months. Then it sits under snow until April. We plan for both. For summer we look at where the evening sun lands, how far the patio is from the kitchen door and where the grill and the fire table will go. For winter we look at where the roof sheds snow and where meltwater will run.
A patio poured against a house needs an isolation joint between the slab and the foundation. The house foundation goes below frost and stays put. The patio sits on the surface and can rise and fall a little each winter. If the two are locked together, something cracks. The joint lets them move apart. We also slope the slab away from the house so breakup water does not run to the foundation.
For the surface, a broom finish is the safe choice here because it grips when wet or frosty. Stamped and colored patios are popular too, and they hold up when they are sealed and when the sealer has a grip additive. We do not recommend a slick, steel-troweled finish outdoors in this climate. Tell us how you want to use the space and we will lay it out with you on site.
Patios in Anchorage: common questions
Will a patio crack from frost in Anchorage?
Any slab can crack, and joints are there to control where. Frost damage is mostly a base problem. A patio on drained, compacted gravel with air-entrained concrete handles Anchorage winters far better than one poured on topsoil or silt.
Can I shovel or use a snow blower on a stamped patio?
Yes. Use a plastic shovel edge or set the blower skids so metal does not scrape the sealer. Skip the deicer on decorative concrete, especially in its first winter, and use sand for grip.
How long do I have to wait to put furniture on a new patio?
Light furniture can usually go on after about three days. Wait about a week for a heavy grill, a hot tub delivery or anything with small feet that carries a lot of weight.
