Glazed brick has had a love/hate relationship with the real estate, design, and construction community for well over a century. In 2011, the New York Times ran an article in the real estate section stating that during the middle of the last century, “glazed brick was supposed to make...

Decades ago, abrasive cleaning of façades typically involved application of sand or aluminum oxide media against building walls at high pressures (i.e. 5516 kPa [800 psi] or more).

When an exterior wall leaks, rots, or falls down, scrutiny of the design and construction can be expected to focus on the inevitable question: whose fault was it?

Evidence of water leakage was reported in a recently constructed three-story building located in a moderate climate, including staining observed at a few locations on interior finishes.

Apart from aesthetics, when brick is selected for new construction, test data provided by the manufacturer is often reviewed for strength, saturation coefficients, and perhaps efflorescence. Unfortunately, another important characteristic—the initial rate of absorption (IRA)—sometimes receives little attention.

The control and management of rainwater on and within a curtain wall assembly is critical for long-term performance and durability. Water-control strategies—most commonly drainage or barrier (exclusion)—can vary by system type and glazing technique.

In modern buildings, there tends to be moderate tolerance for design/construction errors affecting thermal performance, air leakage, and moisture migration. This is primarily due to the typically low interior moisture levels found in these types of projects and seasonal variation in exterior conditions.

Using a mortar harder than adjacent stone or brick can affect the adjacent masonry, from localized spalls along the edges of the mortar joints to severely deteriorated masonry units surrounded by intact pointing mortar.

When designing repairs to existing buildings and structures, emphasis is typically on durability, with the goal of achieving the longest-possible service life. However, there are some cases in which it is desirable to design repairs that are reversible or removable.
