As building envelope professionals, we can’t emphasize enough how critical the waterproofing discipline works alongside a structural team during and beyond construction.

The Champlain Towers South building collapse is a disaster beyond belief. First responders continue to dig out the rubble upon publication of this article.

We acknowledge their dedication and professionalism as they work to find those loved ones who are unaccounted for.

It is so important to be able to identify adverse moisture and water-related conditions early. Such specific conditions may end up affecting the building assemblies that may result in degradation of structural capacity.

Depending on the building assembly type, the degradation could be slow (masonry assemblies) or rapid (wood assemblies). However, in both cases, unless the source of the degradation is repaired and the intrusion is mitigated, the degradation can and will lead to an eventual structural compromise that can result in a catastrophic failure.

It is very critical for building professionals to survey their buildings and mitigate/repair any attributes that may be the cause or contributing factors of building assembly degradation.

Allowing the building components to “live” in an environment that is non-standard and lends itself to degradation can place the entire building in unchartered territory that lends itself to an unknown reduction of the building’s expected lifecycles and renders the structural experimental rather than predictable.
