Durable Waterproofing for Concrete Masonry Walls: Redundancy Required

A single-wythe concrete masonry wall may be a cost-effective structural element, but it can present challenges for waterproofing. The National Concrete Masonry Association (NCMA) recommends redundancy to keep concrete masonry walls dry through techniques at the surface of the wall, within the wall, and through adequate drainage systems. Unfortunately, many concrete masonry wall designs rely solely on admixtures in the concrete masonry units (CMUs) and mortar and surface-applied water repellents. However, low absorption values do not guarantee water penetration resistance; this disconnect in the industry is a leading reason for leakage in single-wythe concrete masonry walls.

“A building is only as strong as its foundation,” is a common idiom uttered across the construction industry. Time can be spent applying this to anything, in the metaphorical sense, but in the construction business it can be taken literally. The foundation is literally the building block on which the rest of a building will rely for long-term function and performance.

Protecting Infrastructure from Major Floods

Initiatives to protect important data servers from major damage too often occur after the event has finished its destruction. By implementing long-term waterproofing solutions (including concrete walls around sensitive space) to key areas, infrastructure can withstand high water exposure caused by massive flooding. This article examines waterproofing and dampproofing admixtures, among other techniques.

Ensuring Balcony Durability: Waterproofing details that stand the test of time

The durability of wood-framed balconies varies widely, with too many suffering from leaks, visible damage on the finishes below, and concealed structural damage from continued water migration. Balconies are vulnerable to decay because they catch rainfall and direct it to a myriad of intersecting planes. There are subtle—but important—differences between the construction of balconies that function for the design life of the building and those failing prematurely. This article presents successful design and construction practices based on a visual survey of over a thousand balconies, excavations into over 200 balcony soffits to check for structural damage, destructive evaluation of selected balconies, and water testing.
