Historic Mortar Replication & Pointing


A Cast Iron Star is Born - 19th Century Masonry Wall Ties

1.0 LU/HSW

Tuesday, March 2 | 12 - 1:00 p.m. EST


A Cast Iron Star is Born reviews late 19th and early 20th Century masonry structural wall ties, which are often found in antique stores as cast iron stars. Structurally significant cast iron stars are often overlooked as interesting architectural features and consequently do not get replaced when missing during building renovations. Learn about the historic and current building code requirements for the wall tie systems along with historically sensitive mitigation considerations when redeveloping historic brick buildings.

Masonry Movement Joints: Structural Edition

1.0 LU/HSW

Wednesday, March 10 | 1- 2:00 p.m. EST


Learn about the movement characteristics of structural masonry wall systems. We’ll compare the differences between movement joints in architectural veneer and in structural reinforced masonry. There are many types of masonry movement joints and strategies. After this session, you’ll be able to identify best practices for detailing movement joints to accommodate and/or restrict masonry material movement.

Historic Mortar Replication & Pointing

1.0 LU/HSW

Tuesday, March 16 | 12 - 1:00 p.m. EST


Get an overview of historic mortars, components, profiles, and purposes to help you develop appropriate replication and pointing mortars for historic masonry projects. We’ll discuss both historical cementitious binders and modern materials. All too often, new pointing mortars that are denser and stronger than the original mortar leads to moisture entrapment and damage to original masonry materials. In this session, we’ll focus on the lime cycle, differences between non-hydraulic and hydraulic binders, and how they affect mortar properties. You’ll gain an understanding of the methodology for assessing existing mortars and developing appropriate replication mortar mixes. Laboratory mortar analysis can be complex. We’ll break down elements of testing that are practical and helpful for mortar replication. In addition to understanding the original mortar, how to analyze it, and how to use this information to replicate mortars, a successful project also requires knowledge of how mortar is installed. We’ll explain mortar removal and installation techniques and provide quality control recommendations. You’ll also see demonstration videos from knowledgeable masonry restoration craftworkers who illustrate best practices.

Design and Detailing of Reinforced Hollow Clay Masonry

1.0 LU/HSW

Thursday, March 25| 12 - 1:00 p.m. EST


Design and Detailing of Reinforced Hollow Clay Masonry presentation explains the brick making process, including specialty shapes and the associated physical properties of fired clay materials. These properties require different detailing than concrete masonry, which is explained and described, followed by examples of its durability related to projects which provide resistance to thermal gradients, wind pressure, blast, and seismic forces. Economic uses are shown along with other unique applications and uses.
