In this episode, we explore the history, science, and modern applications of concrete, from ancient Roman innovations to today’s high-rise structures. We discuss the evolution of cement types, the role of reinforcement, common concrete components, and issues like carbonation. We also touch on futuristic possibilities for concrete beyond Earth, making this a comprehensive introduction for surveyors, engineers, and enthusiasts alike.

This episode explores stone as a building material, from its geological origins to its enduring role in architecture. We cover UK stone types, how stone is quarried and used, why it’s both durable and beautiful, and what surveyors must observe on inspections. Featuring real-world examples from York Minster and Aberdeen, plus practical tips and sustainability insights, this is a complete guide to understanding stone in building surveying.

This episode explores the history, function, and practical impact of mortars and renders in traditional and modern construction. We examine how lime mortar, with its breathability and flexibility, became a cornerstone of historical building techniques, and why it's still vital in conservation today. We break down the key differences between non-hydraulic and hydraulic lime, cement mortars, and hybrid mixes, focusing on their performance, compatibility, and risks. We also explore traditional and modern render types-from Georgian lime renders to pebbledash and silicone systems-and their role in protecting and expressing a building's character. Real-world surveying insights show how incorrect repairs, like cement overlays on lime joints, can damage historic brickwork and what to look out for in the field. We close with a look at modern mortar additives, explaining when they work, where they fall short, and why understanding context is essential for getting it right. A must-listen for surveyors, builders, and anyone passionate about the materials that hold buildings together.

Explore the evolution of bricks in British construction — from Roman forms to Victorian patterns and modern applications. This episode guides surveyors through brick types, sizes, colours, bonds, and their structural meanings, helping you decode the history and performance of buildings one brick at a time.

This episode explores the fascinating journey of clay from raw earth to enduring brick. Discover how local brickmaking shaped Britain’s architecture, the unique role of dustmen in London’s Yellow Stocks, and how firing techniques influenced brick quality. Essential listening for surveyors wanting to read the past and understand the technical behaviours of brickwork today.

In this foundational episode, we explore why understanding building materials is essential to every competent surveyor. From lime mortar and Flemish bond brickwork to post-war repairs and hidden Blitz damage, we uncover how materials, history, geology, and local weather all shape the condition and performance of a building. This episode introduces the tools of observation that will guide the entire series-reading the materials, not just recording them.
