Stone Selection
Granite, limestone and local fieldstone behave differently underfoot and against frost. How to match stone to a path's use and drainage.
Read articlePractical reference notes on selecting stone, preparing a base that resists frost heave, and laying garden walkways that hold up through Canadian freeze–thaw cycles.
Most path failures trace back to one of three stages. These notes treat each one separately.

Read articleIn a large part of Canada the ground freezes and thaws repeatedly each year. Water trapped under a path expands as it freezes and lifts whatever sits above it. A path built on bare soil tends to tilt and separate after a single winter.
The notes on this site keep returning to the same principles: move water away from the path, build on compacted granular material rather than topsoil, and leave the joints free-draining. These are long-standing dry-stone practices rather than products.
