How will the concrete in my dome withstand the effects of freezing temperatures?
Concrete is an excellent and common building material in all temperate zones throughout the world. Concrete is only affected by freezing temperatures when it is porous and absorbs water. The richness and density of our concrete prevents water absorption which spoils the surface when it freezes. Our concrete is also formulated with an air entrainment admixture which further improves the freeze-thaw characteristics. The exterior paint is an additional seal to any water that could freeze inside the concrete.
