Conclusions
• Flooding of chapel by creek water
• High groundwater level
• Water in crypt
• Water uptake by walls
• Drying at internal and external surfaces of walls
• Relatively high vapor diffusion resistance painting
• Moisture source in chapel
• Measure:
Injection of foundation with water-repellent chemical
