2.30 2-Day Retaining Wall Workshop – Pennsylvania
Please note: This is the Two day version of the Retaining Wall Workshop - Specifics forthcoming
Apply the principles and methods for building a structurally sound dry stone wall to building a retaining wall. Learn the fundamentals of retaining walls; did you know they are also double-faced? Sort and stage stone for the build, assist in batter frame setup, and build a retaining wall.
Workshop Objective:
To extend the basic principles of dry stone walling to retaining wall construction.
Learning Outcomes:
- You can describe how the five basic rules of dry stone walling apply to retaining walls.
- You can state how your skill using batter frames and stringlines has improved.
- You can describe how to manage materials and workspace safely and efficiently.
- You can compare basic methods for dealing with drainage and backfilling.
Come learn how to apply the knowledge you gleaned from an introductory workshop to building a retaining wall. Here you focus on structure to maximize strength for a retaining wall that will last for generations. While all the principals of a free standing wall apply, you face additional considerations when building retaining walls.
As in an introductory workshop, you start by evaluating the structure of an existing retaining wall before stripping out and sorting the stone. With your classmates, you will deconstruct and rebuild an existing wall built to Dry Stone Walling Association certification test specifications. Taking apart a wall allows you to understand its structure and the methods used to build it.
As you dismantle the wall, together you examine and discuss the characteristics of the retained earth/gravel bank and the issues that various soil types may present. Begin the rebuild with a focus on establishing a solid foundation. Here is where you address questions related to excavation and drainage. Next, set batter frames and stringlines and continue to practice and improve your skill at building level courses and an even wall face. Extend your understanding of how throughstones promote a durable structure. Backfill the wall carefully and thoroughly into the bank.
Whether you are a homeowner or a professional, by day’s end you can expect to have learned enough to make wise decisions on your own projects. You can apply what you learned directly to all types dry stone retaining walls, from seat walls, to excavator set boulder walls.
The variety of stone you work with depends on the geology of the training site where you have come to learn. In the Northeast and Upper Midwest, you are likely to encounter round field stone, granite, gneiss, and bluestone. In Pennsylvania and Tennessee, you are likely to be working with sandstone. At every Stone Trust training site, you will engage in hands-on experience with the basic rules of structural dry stone walling to apply directly to all types of dry stone projects.
Come learn from certified waller-teachers, most of whom earn their livelihoods as dry stone walling professionals. All Stone Trust instructors have achieved DSWA Level 2 Waller Certification, globally recognized as the professional standard. As Stone Trust-DSWA-certified instructors, all belong to a learning community that seeks to ensure that every one of you learns what you came for and that you enjoy the process. With a student : instructor ratio of 8 : 1, you can count on plenty of direct interaction with your teachers. Introductory workshops tend to include up to sixteen participants working with two experienced waller-teachers.
