    Installing your own pattern imprinted concrete driveways in cold weather

    As the winter draws in, you might think of packing up your tools and leaving any pattern imprinted concrete driveway and pattern imprinted concrete patio work until next year, when spring starts to draw in. After all, the cold weather can have a lot of negative effects on concrete projects, making it hardly worth it?

    We would say yes and no. The cold weather does present you with some challenges when installing concrete, but it is by no means impossible. Let’s look at some tips for beating Jack Frost back from your concrete!

    When planning your winter concrete driveway installation, make sure you have everything ready to go. This includes all your materials, a properly prepared installation site, and weather protection such as insulation materials and heaters. The critical objective is making sure the concrete does not freeze, or get too cold for it to cure properly. This can happen if your concrete loses heat and moisture too quickly at the early stages.

    Planning tips:

    * Using a lower slump concrete is good for cold weather, as it will reduce the necessary setting time and cut down on bleed water.

    * Consider using accelerating admixtures or Type III Hi Early cement. These will get through the critical setting/curing periods quicker, so need protection for less time.

    * Request a preheated mix of concrete from your supplier.

    * Don’t use flyash-containing concrete if at all possible, as it will take longer to set/cure.

    Next up, let’s look at the placement stage. To start with, make sure all snow and ice is removed from the concrete and sub-base. Use heaters to keep the sub-base above freezing temperatures, and try to keep the concrete itself between about 13 and 23 degrees centigrade.

    After placement, don’t start finishing the concrete until bleed water has dispersed. At the same time, you should make sure that the concrete doesn’t dry out complete while curing. And never let ice form on your concrete while it is curing! Ideally you should keep the template of the concrete above 10 degrees centigrade using heated enclosures and/or insulating blankets for about three days to a week after pouring, and then keep it up to at least 5 degrees for four days after that.

    One last tip — when you remove the heating/insulation, do it gradually, so the concrete doesn’t cool too rapidly (by 5 degrees or more per 24 hours).
