Protecting structures from the harmful effects of water
is a key performance criterion in masonry design. Water wicking into unprotected
concrete masonry units and mortar can lead to efflorescence and staining.
In constructing the new Student Services Center, the architects were able
to relate to the neo-Gothic style of the older buildings with split-face
concrete block. It is an attractive and cost-efficient alternative to
The challenge was met by specifying DRY-BLOCK Block
and Mortar Admixture. DRY-BLOCK provides integral water-repellent blocks
and mortar. Minimizing absorption of water into the concrete masonry units
reduces the likelihood of surface staining by efflorescence, mold, or
mildew. The use of DRY-BLOCK enables concrete masonry units to maintain
their appearance over time, contributing to the savings and cost-effectiveness
with low-maintenance. The new building is a successful modern interpretation
of the historic campus structures.
