There are many alternatives to bricks & cement for walls. Each one has its own set of properties.


Concrete Blocks

  • Dense blocks
  • Aerated blocks (breeze blocks)
  • Hollow blocks
  • Patterned blocks
  • Decorative blocks
  • Making Concrete Blocks


Reconstituted Stone Blocks

  • Stone dust, cement & pigment.


Dry Block Walls

  • Concrete blocks are stacked with no mortar
  • Wall is then covered with glass fibre reinforced render
  • The render is a structural element
  • Quicker & weaker than a mortar laid block wall

Adobe

  • Clay suboil, sand, straw or dung etc
  • Blocks


Cob

  • Subsoil, sand, straw, lime
  • Continuous construction, no blocks involved.


Cast Earth


Lime


Sprayed Concrete

  • Concrete is sprayed onto a form


  • Mixture of paper, cement, sand, subsoil, and assorted optional additives
  • Papercrete blocks stacked with papercrete mortar and papercrete render
  • Lath rendered with papercrete is another way to build papercrete walls
  • Many mix variations, some giving high insulation, high strength, or waterproofness.
  • A wide range of waste materials can be incorporated into papercrete.


Earthcrete

  • Subsoil & cement
  • Good for paths


Superadobe

  • Bags filled with stabilised earth used as building blocks
  • Barbed wire included in wall joints for earthquake resistance.
  • http://www.calearth.org/


Rammed Earth

  • Aka pise de terre
  • Earth, sand, gravel, clay
  • A stabiliser is also needed in our wet climate, such as cement, lime or animal blood.
  • Continous build, no blocks


Roman concrete

  • Lime, pozzolan, sand & stone.


Sod

  • Turf strips are stacked.
  • Contains topsoil, grass and roots.
  • The plant fibres stabilise & reinforce the soil
  • Rendered, often with mud plaster.
  • A zero material cost walling option


Straw Bale

  • Bales are stacked & the wall plastered
  • Bales may be load bearing, or a separate wood frame can be used with bale infill.
  • Very low cost
  • Very fast construction method
  • High thermal insulation
  • Excellent sound absorption.
  • Leaks must be repaired immediately to avoid rot
  • Can be built by children
  • Makes very thick walls
  • Render & plaster cover prevents combustion


Rice hull bag walls

  • Steel mesh forms each side of the wall
  • Space filled with polypropylene bags of rice husks
  • Barbed wire included in courses
  • Good Insulation
  • Quick construction


Mudbrick

  • Unfired clay bricks
  • Short life expectancy, around 30 years


Gabions

  • Steel mesh cage
  • Filled with stone
  • Useful for retaining walls


Stone

  • Types of stone wall:
    • Sawn (smooth faced blocks)
    • Hammer dressed (rough faced blocks)
    • Rubble walls (meaning random sized uncut stone rather than the modern usage of the word)
    • Dry stone walling (no mortar used)


Poured concrete

  • Poured into wooden forms in situ


Earthship

  • Stacked tyres filled with rammed earth
  • No material cost
  • Rather ugly in most people's view
  • Bulky
  • Flammable


Drinks can walls

  • Interior non loadbearing wall
  • Drink cans are stacked with wet concrete between them, forming a concrete lattice wall
  • Wall is plastered, the plaster attaches to the ring pulls


Glass brick


Hollow Ceramic Blocks

  • Lightweight lattice-like fired clay blocks are stacked
  • Wall then rendered


Ceramic Pots

  • Plant-pot like ceramic pots are stacked
  • Wall then rendered
  • Popular in Spain


Half Timbered

  • Vertical wood studs with close spacing
  • Mud plaster infill
  • Historic construction method for external walls


Wattle & Daub

  • Timber stud framework
  • Woven twig fencing panels (wattle)
  • Plastered with mud plaster (daub)
  • Historic construction method for internal & external walls


Strawboard

  • A one piece sandwich of plaster, card, straw, card, plaster
  • Low cost
  • Good sound insulation
  • Very poor strength, which can cause problems
  • Used between bedrooms in cut price modern builds
  • Brand name Stramit
