Stonework: The Art and Craft of Using Stone in the Garden

TONY DUFOUR, Registered Landscape Architect, Anthony Dufour Gardens

Whether you're considering doing your own stonework or hiring a professional, we'll cover the basics of using this timeless and elegant material. Through lecture and field demonstrations we'll cover different types of stone, construction methods, sources of materials, tools of the trade, and common mistakes. We'll focus mainly on walls and columns, and participants will walk away with an understanding of basic stone types (quarried versus fieldstone). We'll explore cutting, shaping, safety, hand and power tools, and the basics of both dry-laid and masonry construction. After 90 minutes in the classroom, we will move outside for 90 minutes in the field with practical demonstrations. This course has been submitted to carry 3 LA CES CEUs.

Dry-Laid Patios and Walkways: Materials and Methods

TONY DUFOUR, Registered Landscape Architect, Anthony Dufour Gardens

 

Thinking about tackling a new walkway or patio, or rebuilding one? We'll cover exactly how to do this! Through lecture and field demonstrations we'll cover different types of materials such as brick and flagstone, as well as tools and tricks to get the job done right. While we'll focus more on construction and less on design, we will cover why pavements fail and common pitfalls to avoid, how to lay out the space, sourcing materials, cutting materials, and working safely. The emphasis will be on dry-laid construction, but we will touch on advantages and disadvantages over wet-laid (using concrete and mortar). After 90 minutes in the classroom, we will move outside for 90 minutes in the field with practical demonstrations. This course has been submitted to carry 3 LA CES CEUs.
