@civilstudyline: Why protect the bottom 50 cm of the wall? 💧 The lower part of a wall is constantly exposed to water splashes and moisture. A bituminous waterproofing layer behind the plaster helps stop moisture from reaching the wall finish, reducing problems such as damp spots, peeling paint, and damaged plaster. It’s a small construction detail, but it can save the finish from repeated moisture damage. #Waterproofing #Construction #CivilEngineering #WallDetails #BuildingTips #ConstructionTips
