Moisture migration in building walls—Analysis of the interface phenomena

The study of moisture migration in materials and building elements is of great importance for the characterization of their behaviour, and affects their durability, waterproofing, degradation and thermal performance. The different mechanisms of moisture transport in building walls and the analysis of interface phenomena have been investigated. Based on the theory proposed by Luikov and Philip—De Vries, a computer program has been developed. The comparison of calculated and measured values obtained by using gamma-ray equipment to measure water content profiles, is considered satisfactory.
