Hot Weather Masonry – Material Storage
General. All masonry materials must be carefully stored. Masonry sand, when bulk delivered,
should be shaded, sprinkled, or covered to prevent excessive water loss from evaporation.
Bagged materials and masonry units should be stored elevated to prevent moisture migration
from the ground to the materials, and then protected against water penetration through the sides
and the top.
Coverings should be properly installed so that all materials are completely covered.
Tarpaulins, reinforced paper, or other water-repellent sheet materials may be used.
Sufficient space should be provided between the materials and the covers to allow
circulation to take place.
If the weather and size of the project warrant, it is recommended that a shelter be
provided for the materials storage and mortar mixing areas.
Summary. Materials delivered for projects need to be protected from
damage and contamination. Cover sand piles and sprinkle with water as needed to
maintain in damp condition. Cover or shade units from direct exposure to the sun.
