Anchoring in Winter
The key issue is applying the grout -- whether it is cement or epoxy. In both cases the hardening of the grout requires a controlled ambient temperature. For water-based cement (such as our EPX2), the temperature should be above freezing, and the water temperature that is added to the grout powder, should be above 50F.
If you use epoxy as the grout, consult your vendor for the low temperature limit and how to use it in cold weather. We found that preheating the epoxy cartridges before application goes a long way to get the curing to start once the epoxy has been mixed. Some epoxies are really sluggish and will not start curing at temperatures as low as 50F.
If you have a large job with many anchors to install, use a small portable tent with heat lamps.
Remember that the alternative to using anchors is to cut out a large patch of asphalt and pour concrete. And that is not a viable option in freezing temperatures.
As always, search our FAQ and Library for tips and ideas how to install and use our anchors.
