Mud Bricks

Mud Brick Basics

• One of the oldest building materials (used for thousands of years)
• Made from: earth + water + straw/fibres
• Shaped in moulds and sun-dried
• Also known as adobe
• Very low environmental impact and embodied energy

Composition

• Clay content: ~30–70%
• May include silt, sand, gravel, and stones
• Should not contain organic matter

Making Mud Bricks

• Mix earth + water + fibres
• Place in moulds (wood/metal)
• Air dry evenly (avoid cracking)

Construction

• Built like masonry (courses + mud mortar)
• Thick mortar joints create a seamless/monolithic look

Structural Use

• Can be load-bearing
• Can also be used as infill in timber frames
• Suitable for arches, domes, and vaults

Why it is an Awesome Building Method

• High thermal mass (stores heat)
• Excellent sound insulation
• Fire-resistant (earth doesn’t burn)
• Resistant to pests
• Can last centuries with maintenance
• Very low energy to produce
• Materials often sourced on-site
• Recyclable and natural
