The Envelope
The building envelope is the physical barrier between the inside and the outside — foundation, walls, roof, windows, insulation, drainage. When it works as a system, a building stays dry, efficient, and sound for decades. When it doesn't, water finds the way in and never leaves politely.
What we protect
01
The pressure barrier between soil and structure.
02
Where vapor, air, and water all meet — and must be sequenced.
03
The top coat of the whole building, made to shed and move.
04
Transitions, flashings, and the seams everyone forgets.
05
Where energy performance and moisture meet.
06
Directing water away long before it finds a weakness.
The forces
Every building gets tested eventually. These are the four forces doing the testing — and how we engineer each one out of the equation.
01
Water under pressure is a structural force, not a leak.
Below grade, soil holds water against the foundation. Gravity turns that water into pressure that pushes against — and eventually through — concrete, cracks, and construction joints. Effective waterproofing isn't a coating; it's a pressure barrier plus a drainage path that relieves the load before it becomes a problem.
02
Moisture doesn't only fall; it travels through walls as vapor.
Temperature differences drive water vapor through building materials, from warm toward cold. When that vapor hits a surface below the dew point, it condenses — inside the assembly, where you can't see it. We design the assembly so that condensation either can't form or ends up exactly where it can safely drain.
03
The gaps you can't see are the holes that cost the most.
Small openings let air — and the moisture it carries — move in and out of the envelope. That's how energy escapes, how temperatures uneven-up, and how hidden condensation develops inside wall cavities. An envelope without an air barrier is an envelope with a chronic, invisible leak.
04
We design for the water that will come, not the water that might.
The modern principle of water management is blunt: assume water will occasionally get behind the exterior. Then control where it goes and give it a clean way out. Every assembly we touch gets a drainage plane and water-management strategy — not a hope and a prayer.
Water management
The old assumption was that water would never reach the structure. The realistic one is that water will get behind the exterior on a bad day — so the design’s job is to control where it goes and how it exits.
That means drainage planes that route water down and out. Vapor barriers placed on the right side of the assembly. Transitions detailed like they’re load-bearing. The buildings that stay dry for decades aren’t luckier than the ones that don’t — they’re better designed.
Below grade — before backfill
The layer between the soil and the structure is the one you only get one chance to do right.
