Mud can be made into mud bricks, also called [[adobe]], by mixing mud with water, placing the mixture into [[molding (process)|moulds]] and then allowing it to dry in open [[air]].<ref>{{cite web|url=http://www.yourhome.gov.au/materials/mud-brick|title=Mud brick|last=admin_666|date=29 July 2013|work=yourhome.gov.au}}</ref> [[Straw]] is sometimes used as a [[binder (material)|binder]] within the [[bricks]], as it makes them a [[Composite material|composite]]. When the brick would otherwise break, the straw will redistribute the force throughout the brick, decreasing the chance of [[Structural integrity and failure|breakage]].<ref>Smith, Michael G. ''The Cobber’s Companion: How to Build Your Own Earthen Home''. Cottage Grove: Cob Cottage, 1998. Print.</ref> Such buildings must be protected from [[groundwater]], usually by building upon a masonry, fired brick, rock or rubble foundation, and also from wind-driven rain in damp [[climate]]s, usually by deep roof overhangs. In extremely dry climates a well-drained flat roof may be protected with a well-prepared ([[Puddling (engineering)|puddled]]) and properly maintained dried mud coating, viable as the mud will expand when [[moisture|moistened]] and so become more water-resistant.<ref>{{cite web|url=http://www.nps.gov/tps/how-to-preserve/briefs/5-adobe-buildings.htm|title=Preservation Brief 5: Preservation of Historic Adobe Buildings|work=nps.gov}}</ref> Adobe mudbricks were commonly used by the [[Pueblo]] [[Native Americans in the United States|Indians]] to build their homes and other necessary structures. In some countries there are entire cities made of mud brick houses.
[[Cow dung]] and [[biomass]] are added to regulate indoor climate.<ref>[https://www.tudelft.nl/2020/citg/bricks-made-out-of-mud-and-cow-dung-to-regulate-indoor-climate Bricks made out of mud and cow-dung to regulate indoor climate]</ref>
