Hybrid construction combines multiple building techniques to form a livable structure. Materials and techniques used in hybrid construction are usually decided based on several factors including, cost, visual appeal, structural integrity, natural resources and production time. Hybrid construction could include traditional forms of masonry combined with recycled materials and natural building techniques.
Wood frame construction is possibly one of the most common building techniques used world wide however in South Africa wood is only used in far more expensive applications. Buildings using wood frame can be constructed to be load bearing or non load bearing and plans are more likely to be approved by local banks as is.
Cordwood construction, also known as cord wood masonry, stack wall construction or stackwood construction is a a natural building technique where cordwood, logs or short lengths of de-barked tree are laid with masonry usually concrete to build a wall. The wood is stacked one piece at a time and concrete fills the gaps between each.
Strawbale construction is a technique that utilizes straw bales as building bricks and insulation in the straw bale structure. Straw bales are being more often used in new “natural building” structures. The straw construction has several advantages over standard construction methods due to its low-cost, high-availability and thermal-insulation properties. The basic techniques used in straw.
Earthbag construction is a cheap, strong way of building. It uses a natural construction method based off army style bunkers and flood-barrier building techniques. The earth bag construction requires very basic materials: sacks (hessian, canvas, cotton, plastic), filler (gravel, sand, concrete, clay) and wire or barbed wire (using the sharp points in the wire as.
Poured earth is mixed and formed similar to concrete and uses cement as the main binding agent. So instead of using gravel or sand as is the usual in aggregate in building with concrete, poured earth uses ordinary soil and less cement. The poured earth mixture is pumped into a pre-built shutter system and left.
Rammed earth construction, is also known as “pisé de terre” or “pisé”, is an ancient building technique that has been recently revived by people looking for low-cost, environmentally friendly construction materials and more natural building techniques. Rammed earth buildings essentially compress a dampened mix of soil, gravel, cement, sand and clay, into a supported shutter.
Cob construction usually uses sand, clay, water, earth and straw in a technique very similar to adobe. Cob is a very fire resistant material and is also maintains good strength in earth quakes most of all Cob construction is relatively inexpensive.
Short Description of Adobe Construction Adobe is a natural construction material mixed together with clay sand, & dung, straw or other materials containing fibers, this mix is then molded / formed into individual bricks using a frame system which is then dried out in the sun. Adobe construction is very similar to mud-brick and cob.
