Advanced Laying Techniques Module 28205-05

Upon completion of this module, you will be able to: Transparency 1 Objectives Upon completion of this module, you will be able to: 1. Recognize the structural principles and fundamental uses of basic types of walls. 2. Recognize the requirement for, and function of, control joints and expansion joints. 3. Build various types of walls using proper reinforcement, jointing, and bonding techniques. 4. Lay out specialty structures such as maintenance holes, segmented block walls, and screens. 5. Identify and explain the different types of masonry arches used today. 6. Lay out a semicircular arch and a jack arch.

2. Lay out specialty structures and arches. Transparency 2 Performance Tasks 1. Lay a wythe of brick against a block wythe or wood frame backing to make a composite wall. Use ties and a collar joint. 2. Lay out specialty structures and arches.
