Building Envelope – Built by Chemistry

Building Envelope Ed #13

Two waterproofing systems on one basement wall. When the redundancy works, and when they fail together.

Crystalline admixture plus liquid membrane in a basement wall. When redundancy works, when both fail together, and the sequence that decides between them.

Building Envelope Ed #12

The flat roof that leaks at year three. Three real cases. One test nobody runs.

Three flat roof waterproofing failures: why the membrane passes EN 1928 but the seam and interface fail in 3 years, and the fixes procurement misses.

Building Envelope Ed #5

Waterproofing Failures Are Almost Never the Membrane's Fault

Waterproofing fails across India. Almost never because of the membrane. Three real failures, three real causes — Delhi to Rajasthan.
