How to tell dangerous cracks (from settlement/earthquakes) apart from expansion-contraction cracks.
Plaster Blistering & "Hollow" Sounds
How to detect adhesion loss (with a light tap) and trapped moisture.
Rising (Capillary) Damp
How water rising from foundations erodes and destroys renders at the base of walls.
Salt Efflorescence on Plaster
What causes the white stains that appear externally and why they make paint peel.
Cracks in ETICS Thermal Facades
Layer failure, poor mesh embedding and the most common mistakes that lead to cracking.
