Cautions

a) Make sure that there is plenty of clean and cold water and towels on the job.

b) Make sure the temperature of the holes meet the requirement before loading.

c) Make sure the holes are clean and no water and residues are left in the holes, use high-pressure air to clean out so the loading depth is 100% of the pre-drilled holes.

d) There should be a sufficient number of workers on the job to take synchronized steps when mixing, stirring and filling so that the expansive mortar will be poured into the holes within 10 minutes after mixing is completed, this will guarantee that the maximum expansive stress of all holes occurs at the same time.

e) If the mortar start to get warm and bubble before finish loading, don’t fill it in the holes, it must be discarded, it is forbidden to fill into the holes and it could cause the mortar to blow out of the holes.
