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 brickwork on the inside we where












And then it was finished

    What very small lifts of soil, makes the wall look like courdroy!

To Open a blog again and write down what we have been up to for the past two years seems like a daunting task but just feel we should document some of the work we have done Largest Rammed Earth Structure in South Africa Hoyo Hoyo Conference center  This building surprised the client from start to finish what was planned to be a convenience store turned into the most beautiful and eye catching buildings in the Acornhoek area close to Hoedspruit    We used  a mixture of face brick and rammed earth as well as some insitu concrete beams to span the eight meter  door the Rammed earth used here has tested in the region of 28MPA which is huge strength totally unnecessary but has given birth to a very hard durable building that will be maintenance free for many years to come Eight hundred meters under roof for  Two thousand per meter   Green Building at less than a quarter conventional cost The Rustic building gave space to do an unconventional floor

Rammed earth specifications and history

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-
