It is even possible to cast the window opening to a profile that can be glazed directly without a frame. the walls and roof do not need to be painted simplifying maintenance. The walls must be a strong base for the roof as well. A lot of information on low cost and affordable foam concrete housing is available, mainly from suppliers who are promoting their own products and systems. 3)The roof It is better to have the same layout with a different colour wall finish, than a different layout with the same colour. Concrete is one of the cleanest and most versatile types of wall material available. when all the panes are done they can be used the same way as regular SCIP panels are to assemble the walls and roof. The walls require a high quality formwork system that often is not locally available and might need importing as well. Any type of window frame can be used, such as locally produced steel windows, timber windows and aluminium window frames. The houses must be cheap, yet very durable and able to bring comfort to its occupants. As a European, I was frustrated at the apparent lack of alternatives to the conventional block and brickwork for walls. This would allow a very efficient and flexible use of the mould system. I think the Structural Concrete Insulated panels may be the winner when it comes to building a little house you can call your own. Complicated wall junctions, corners other than of 90 degrees should not be used, and walls should all be on one level. The fluid nature of Porofoam allows the concrete to free flow into even the smallest of spaces making it highly suitable for voidfill applications. Ferrocement requires a lot of labor to twist the wires to secure the mesh to a steel framework, it is tedious but very simple work. A.2.8 M+E Installations In order to clear the back log by 2030, an additional 14 million units per year are required. The cells, or bubbles are discrete and range in size between 0.1 and1mm. Foam concrete is a type of lightweight concrete that is manufactured from cement, sand or fly ash, water, and the foam. Electrical installation can also be fixed to the wall surface as cellular concrete is suitable to be nailed and screwed. Cellular Lightweight Concrete or foamed concrete producing technologies. ICFs are stable, even in an earthquake. Please note that not every wall thickness can be realised with standard formwork panels. Openings in the wall can be made by inserting block-outs in the mould. Create an energy-efficient and sustainable building with SmartBlock Insulated Custom made panels should be avoided where possible as they are expensive, require longer production time and add to the overall cost. These fully assembled blocks feature rugged 2 3/4” foam panels for a typical wall assembly R-value of R25. that the roof can also be built with the same material you build the walls and. There are dozens of low cost home building methods that have been promoted for years. Concrete walls are stronger, however, Florida Foam Walls are engineered to withstand a hurricane in excess of 130 MPH. As a rule, the foam concrete (FC) allows stripping the next morning so that the walls of the next house can be cast on that same day. Concrete structures can be among the safest and most durable types of structures in an earthquake. On a recent project, I specified the use of Neoprene foam fillers for expansion joints in the clay masonry walls. ... XP-1 is a self-aligning complete solution for ICF walls with exposed concrete. Please note that in cyclone prone areas a much stronger roof structure, panels and fixings are required. each side of the panels would be attached to each other by the steel tubing that is inserted into the foam. These products are without exception of constant dimensions and of consistent high quality. Reference Table for "U" Values "U" Value is the coefficient of transmission, i.e., the transmission of heat through the materials, which compose the building's "envelope," or outer shell. Acoustical applications and fire-retardant properties increase the value of this construction method. I am thinking a person could assemble a jig to drill holes in foam panels and insert short pieces of steel tubing into the holes in the foam. Floating raft foundation is the preferred type of foundation as it is a stable base for the walls. External walls, or part of it, can be cast with a textured surface by using polyurethane rubber mould liners. Foamed concrete (CLC) panels can be used to build partition or non-load bearing walls. FC does not use gravel and because of the high air content, uses less sand. In general, layouts must be simple. The height of the walls should be conform the standard height of the mould panels: as a rule they come in standard height of 2.70m or with some systems 2.64m. A.2.3 Roof (Engineer’s design) Starter bars tie the walls solidly to the foundation. Depending on soil conditions, different types of foundations can be applied. Where a high insulation as well as high strength is required, the wall thickness might have to be increased to 150mm or even 200mm. That means that in the morning the moulds are stripped from the earlier cast house structure, cleaned, treated with releasing agent and set up on the next foundation and cast in the afternoon. The function of the foundation is to carry the house and its loads (vertical forces) and to transfer horizontal forces (wind) to the underground. There are several ways to add architectural features to the design (of the walls) of the houses. Wall structure with roof structure in place. Surface-mounted piping is of course possible as well. Once the mould for the walls is set up and ready for casting, it is filled with lightweight concrete. The molded foam blocks replace traditional forms and, since they remain in place after the pour, they provide excellent insulation and sound dampening qualities. Different sizes of layout should preferably be designed as a family, meaning that increase in size should rather be found in inserting extra wall panels in the configuration of the smallest unit. This means that the formwork for the walls is stripped and  erected on the next foundation in the morning, and is cast the same day and stripped the next morning for the next cycle. Making the panels yourself would save a great deal of money. Toilet bowl and cistern, bathtub, basin and shower/bath are part of the house and the piping for water supply as well as the waste water discharge piping need to be exactly planned and incorporated in wall and floor slab. Poured Walls IFCs are hollow foam blocks that are stacked into the shape of the exterior walls of a building, reinforced with steel rebar, and then filled with concrete. If a raft is used for the foundation, it is advisable to use a mechanical float to get a smooth floor finish. by adding extra panels to the mould the size of the house is increased. Where applicable the use of in-house heating and/or cooling can be reduced thanks to the insulating properties of CLC. Doorframes can be placed inside the mould and cast in. One mould produces all the walls for one house per day. If you are building by your self or with just one helper to save money in your spare time you don't want your site to have a half framed wooden building for too long as it could attract vandals. I read in one of your articles when putting up rigid fome to Install two inches of rigid insulation board directly against concrete. How to Form Concrete Walls. No clay is used as clay (bricks) is a valuable material for agriculture. Insulated concrete form walls are constructed by pouring concrete into hollow pre-formed panels, which are most commonly made of expanded polystyrene or extruded polystyrene foam. I have looked at underground, adobe, cobb, strawbale, dome, log cabin, log stackwall, stone, sod, sandbag, steel panel,Earthships,converted industrial buildings, houseboats, converted trailers, Cinva ram blocks, plywood, containers,  SIPs, yurts, domes, motorhomes, vans,treehouses, railroad cabooses, railroad ties,wood frame, bamboo huts, gancrete, papercrete,ferro cement  and wattle and daub! 1) The foundation and ground floor In case of pitched roofs, all top surfaces must be closed to prevent the overrun of foam concrete. Standard wall thickness is 100mm, but walls can be produced in other thicknesses as well, from 60mm up to 200mm, depending on the function of the wall and structural requirements. In areas of increased stress additional reinforcement bars will be required, such as around openings in the wall. Insulation blanket on top of ceiling helps to keep the house cool inside. A.1.4 The Foamwork System Doorframes can have the same thickness as the wall, or can be less thick in which case a block-out must be used to add up to the thickness of the wall. After stripping the wall moulds, the roof structure can be placed and fixed to the walls by using the cast-in anchors. The houses can be built as basic house or as a more complete house; all houses though are very suitable for future upgrading and extending. The Solarcrete insulated wall panel system can save you 60 - 100% in heating and cooling energy costs over traditional construction methods. By using modern construction methods, the quality of the built houses is mainly controlled by the system. Discover how to build better using Logix Insulated Concrete Forms & Concrete Wall forms in your ICF Home Construction. Generally speaking, only the foaming agent, polypropylene fibres and specialised equipment such as the foam generator needs to be imported. The insertion of foamed-concrete insulation can probability be automated. Foam concrete consists of sand, cement, water and foam (air) and is used for all walls. Higher pitch is more difficult than lower pitch. This is exactly the kind of description that we would like to apply to the construction of low cost housing. FC ages very well and is a responsible long term investment. Walls Each Foamwork mould produces one house per day An essential part of the system is the daily production cycle. the concrete creates a monolithic structure that is earthquake resistant, hurricane resistant, fire and pest resisitant. Steel and plywood formwork mould,South Africa. Where flooding might occur, the level of the floorslab should be raised. Walls made with ICFs withstand more than 4 hours of continuous fire and remain structurally sound protecting your home and belongings. Should the insulation be: foam board against concrete foundation, then the stud wall then the dricore up to the stud wall wall or should it be: dricore up to concrete wall, foam board over the dricore with stud wall on top of the dricore. Although they do not function as the primary reinforcement, the fibres highly improve the quality by toughening the wall and by limiting surface cracking in the initial setting after casting. Assembly line principles for the sequence of activities for preparation and work on the construction site. A qualified Structural Engineer must be engaged to design the foundation, structural walls and overall structure in line with local Regulations and prevailing conditions. The most suitable foundation is a reinforced dense concrete or foam concrete raft slab that together with the walls forms a strong and stable boxlike structure. The panels are a sandwich of foam that has wire mesh on the outside and each side of mesh is connected to the other with mesh that goes through the foam and unites both sides. The most important rules are: A.3.2 Layout etc. The use of moulds result in very fast production of huge amounts of products. More moulds would deliver more houses per day. The most important components of these type of houses are the foundation and the walls. )the second advantage is I think the panels can be made and  assembled at home by a single person so you would not have to buy them from a company already assembled. In fact, any type of roof can be applied, according to locally available materials, usage and regulations. because the roof is one piece there is no way for a shingle to come off during a hurricane and create a weak spot that would cause you to lose your roof. A.2.7 Ceiling Moulds can be filled by hand,Tsakane,South Africa. However any kind of flat ceiling or ceiling that follows the roofline can be installed. Foam concrete is in the form of foamed grout or foamed mortar. © 2016 Foam Concrete Housing | D5 CORPORATE LITE Theme by: Part 1: Introduction to Foam Concrete Industrial housing. Dimensions Height of the walls should be in accordance with the height of standard panels of the mould system, for most mould systems this is 2.70m. A mold expert told me to put the board on top of the framing, not directly onto the concrete wall so the house can breath. Ted Gorab Published: Oct. 3, 2019, 6:09 p.m. Last updated: Aug. 6, 2020, 11:52 a.m. Water piping can be installed in the wall, and where required, openings in the wall can be made to allow pipes to pass through the wall. Steel bars are used to reinforce the walls according to Engineer’s specification. Call us for more details. A.1.8 Lay-out and Design FC can be produced in many densities, each with its own mix design and own properties for a whole range of applications. Solarcrete is a concrete structural insulated panel wall system constructed with EPS foam and concrete to build energy efficient concrete walls. A.1.7 Local Materials Concrete foam was originally used as insulation in the 1920s. Pipes have to be brought outside the floor- and foundation structure to allow connection to municipal water supply and waste water discharge. Architectural features can be incorporated into the formwork, or, in case the feature exceeds the wall thickness, provisions to fix the feature later can be placed into the mould and cast in. The mould can be used to produce housing units of different size, e.g. A.3.5 Structural Design Formwork in progress, technical installation being installed. A maximum of local materials and products should be used. Generally concrete block walls cost 10-20% more than foam walls. Ventilation blocks can be incorporated in the mould and cast in. These pre-cast panels have hollow cores to reduce weight and gooves so that they interlock. This foam concrete consists of a mixture of sand, cement and water, to which millions of very small air bubbles are added to form a cellular structure. These forms create negative spaces that bring an artistic look to the final concrete cast. As discussed above, IBC Chapter 26 essentially requires a minimum of 1 in.
