(Online Workshop)
Friday February 27th 15:30pm (Approx 1.5hrs)
Ideal For
-
Homeowners and self-builders renovating a stone or solid masonry house

Anyone interested in natural, breathable and sustainable building methods
Course Overview (Homeowner-Friendly)
This workshop explains how stone and brick walls in older homes deal with moisture, and why many modern renovation methods—like cement, tanking slurry, rigid foam boards and plastic membranes—can actually make damp problems worse.
We break down how solid walls work, how they dry, and how to choose the right breathable insulation and finishes so your home stays dry, warm and healthy.
You’ll learn about practical options such as insulating lime plasters, natural insulation boards, lime mortars and vapour-open paints, with clear guidance on what works, what doesn’t, and why.
By the end, you’ll feel confident assessing advice, avoiding the common pitfalls, and making informed decisions for your own renovation project.
