3.2 Cold weather working

Also see:

brickwork and blockwork should not be built when the air temperature is below 3°C and falling
work can resume when the temperature is 1°C and rising with the expectation the temperature will exceed 3°C
materials which have been damaged by frost or are frozen should not be used
additional covers and insulation will be necessary at very low temperatures
polyethylene covers should be used to provide protection and prevent work from becoming saturated (an air gap between the masonry and the covers will enable new masonry to cure)
where very severe frosts are expected, heaters may be required
protection against frost may be required for up to six days, depending on the severity of the conditions.
