    Is it not a good idea to do hardscapes using contrete bases and mortar in the winter time. Do you run the risk of it cracking. where i live its very uncommom for the temps to drop below 20.

    Watch out for efflorescence as well.

    keep the base warm with heaters. the mortar if it freezes will have efflorescents and become very weak. the worst thing you can do is let it go through a freeze thaw cycle. when we do any masonry in the winter we do tents and heaters and add accelorator to the water. we keep our water heated and heat the sand before mixing our mud. concrete is much easier then mortar since it throws alot of heat as it sets.

    Check your local codes. Some places up here have a "Pour Freeze" in place.
