Water finds its way where it can. In buildings, that often means through cracks and around joints that were never meant to seal against the elements. For anyone responsible for a building envelope, the area where crack repair and expansion joints meet is critical. It is not enough to patch a crack or fill a joint once and assume the problem is solved. The real work lies in selecting materials that bond well with the substrate, accommodating movement, and resisting the force

Waterproofing is one of the most stubborn parts of building envelopes. It sits at the intersection of design, materials, and field execution, and when any one of those elements falters, the cost of water intrusion shows up in leaks, dampness, and the slow deterioration of concrete and steel. In this piece, I draw on years spent on projects ranging from concrete podiums to high rise balconies, from below grade foundations to parking structures, and from subtropical climates

Waterproofing a roof deck is more than keeping rain off a surface. It is about guarding the mechanical equipment perched on the roof, preserving the interior spaces below, and extending the life of the building envelope. In subtropical climates where wind driven rain and humidity push against barrier walls and deck joints, a well conceived roof deck waterproofing strategy is a critical component of the overall building performance. The decision to protect equipment like coo
