EWB Walls

When a construction project is carried out, the amount of concrete used is a key factor in the impact we cause to the environment. In addition, in many occasions, we limit ourselves in its use for economic reasons. When we want to make thicker walls than conventional ones, we not only spend more money for the amount of material we need, but also the impact we have against nature is greater. Even it is difficult to go to alternative materials, because we hardly find any that improves the price of cement and offers us the same resistance. However, we have managed to create ecological walls of 61 cm thick much more resistant than one of concrete, which uses 60% less cement, and offers better thermal qualities.


The idea began in 2006, when it was planned to reduce costs in construction materials, designing a wall capable of supporting a concrete slab. Inspired by ICF technology, a wall with thin layers of concrete was developed in conjunction with polystyrene. This significantly reduced housing costs, and offered unique thermal properties that insulated the interior of the high-temperature construction. However, polystyrene continued to represent a negative impact on the environment, due to its manufacturing process.

First prototype of encapsulation

Then a construction method was developed that encapsulated straw inside a mold, which was sealed with concrete. This new method required a lot of ingenuity to achieve the desired product. The walls were submitted to different ballistic and thermal tests, yielding results that exceeded our expectations. It was possible to totally isolate one side of the wall, still subjecting its exterior to temperatures above, 1000ºC. In addition, when measuring the interior temperature of a building, it showed 16ºC less than the outside (when the outside heat was 39ºC).

Final technology

When we thought that we had achieved the best construction system, the idea arose to encapsulate completely raw earth inside the molds. This required a more sophisticated and resistant design of molds, which would have to be practical and portable for their transportation. After almost ten years of work, it was possible to create a revolutionary method to build walls that encapsulate raw earth inside; the same earth that is in the land where it is built. Thanks to this, more than 60% of the use of cement for the construction was reduced, offering much more resistant walls than the conventional ones, offering very high thermal insulation and security. The best thing is that no foundation is required to lift each of these "blocks".

Building with this sustainable technology is inexpensive, since in addition to saving material costs, EWB offers a 10-year construction warranty. Our walls are just one element of a technology that integrates the best in sustainability in one place, and are currently patented for the exclusive use of Eco World Building®.
