RammTeck. Bringing the past into the future

Rammed Earth (pisé) rammed earth walls are constructed by ramming a mixture of selected aggregates, including gravel, sand, silt and a small amount of clay, into place between flat panels called formwork. Traditional technology involved repeatedly ramming the end of a wooden pole into the earth mixture to compress it. Modern technology replaces the pole with a mechanical ram. Stabilised rammed earth is a variant of traditional rammed earth that adds a small amount of cement (typically between 5 and 10 per cent) to add strength and durability. Stabilised rammed earth walls need little added protection but are usually coated with a permeable sealer to increase the life of the material – this varies with circumstance and there are thousands of unstabilised rammed earth buildings around the world that have given good service over many centuries. Most of the energy used in the construction of rammed earth is in quarrying the raw material and transporting it to the site. Use of on-...

Rammteck was formed as one of South Africa's  first rammed earth building companies . Not only to promote the art and science of building in rammed earth but to get out there and design, engineer and build it cost-effectively. To bring rammed earth from the status of a "forgotten art", not practiced  in South Africa , into the mainstream of the building industry. Rammteck rammed earth is now a modern, structural, load bearing, durable, waterproof, beautiful, artistic, breathing, green, cost-effective, environmentally-sound building material. There is an inherent attraction of rammed earth walls to most people. Nearly everyone who sees a rammed earth wall, and almost certainly those seeing one for the first time, walks up to it and touches it or rubs it, since it is such a tactile material. All people comment on the attractiveness of the look and feel of a rammed earth wall. When walls are being built and the raw earthen materials are laid out on site most people fin...

Rammteck KZN pilot project This is one of the documentaries on our buildings just a repost on u tube very informative

  Rattray foundation head office O ur most challenging project yet where we had to build on a gradient and the base was all clay Obviously rammed earth adds some additional challenges to this type of construction Embedded in the clay was huge granite rocks that had to be burnt and cooled to break before we could get Down to foundation level All foundations in the basement are reinforced 1m x 0.8 with 16 mm rebar Olso tied to these vertically where tie bars for the retaining wall  this had to be done as  three sides of the wall are holding back the clay The vertical bars that will run up the retaining walls to create a stressed member Shows the bars that will run all the way through the wall to the top of the slab Then two lines of bricks 300 mm apart with our Steal  in the cavity we can lift three lines at a time and then Fill with concrete The following ...

n Tswinga village  This was going to be a challenge with no local knowledge a totally new crew Very bad soil conditions as there was only a clay type of soil to be found I only put two of my experienced staff onto this project.  With my two site leaders so far from home for so long they became  Very friendly with the locals and that lead to a management breakdown Wich was costly to the business Some nice coloring in the wall panels The soil problem lead us to import a lot more soil than we thought necessary We had to breakdown the clay as much as 75 percent this we did with a blend of riversand and cement to achieve the desired hardness issues Getting the patching right on any rammed earth wall is an art but really makes or breaks it  with all the pin holes there are a lot of these visible marks I have a secret remedy for that but drop me a mail After a long ramming process and a lot of intricate b...
