Thixotropy is why the tile stays where you put it. The rheology behind the cream effect, the slip test, and why the datasheet lies at 35 °C.

Thixotropy is why a tile holds on a wall and spreads under the trowel. The rheology, the yield stress that carries the tile, and why datasheets lie at 35 °C.

Polymers 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.
