1. Construction Techniques and Moisture Control Module 28206-05

2. Transparency 1 Objectives • Upon completion of this module, you will be able to: • 1. Explain and demonstrate techniques for constructing masonry around windows, doors, and other openings. • 2. Explain the requirements for wall bracing, and demonstrate the techniques used to construct pilasters and other types of bracing. • 3. Identify the various types of insulation used in conjunction with masonry construction, and explain installation techniques. • 4. Identify the need for moisture control in various types of masonry construction, and demonstrate the techniques used to eliminate moisture problems. • 5. Construct corbeling in a double-wythe wall. • 6. Join intersecting walls. • 7. Install flashing.

3. Transparency 2 Performance Tasks • 1. Construct a four-course corbel starting at the fifth course of a double-wythe wall. • 2. Construct an intersecting block wall joined with wire mesh or metal lath. • 3. Install a row of flashing in an anchored veneered wall.
