Course Title: How to Identify and Mitigate Moisture Intrusion in Structures: Case Studies
Delivery Method: Live Online
Course Description: This course examines case studies of structures damaged by water intrusion. Three cases involve three different causes: design errors, site preparation errors, and degradation of materials. Strategies to mitigate these errors are explored.
Learning Objective 1:
Learners will be able to explain how design errors, construction errors, and deferred maintenance in structures can result in moisture finding ways into buildings.
Learning Objective 2:
Learners will be able to explain how faulty site preparation, poor construction layout problem areas in the building envelop can result in moisture intrusion.
Learning Objective 3:
Learners will be able to explain how building material degradation can allow moisture to enter buildings and lead to mold and poor indoor air quality.
Learning Objective 4:
Learners will be able to evaluate and determine appropriate mitigation strategies to prevent and remedy moisture intrusion issues in structures for the health and safety of occupants and users.
