I was collaborating in the construction of this earthed-sack building.

Hearthed-sacks technique uses long sacks, commonly used for agricultural purposes, filled with hearth and then rammed for compaction. Laid in layers the sacks create a false vault.

It is essential to frequently check the distance to the centre to build an almost perfect circle. 

The building system is very time-consuming, there are a few tens of tonnes of earth in that building, but the results are magnificent.

The use of buttresses is a must because the forces acting on the walls are huge.

The name of the project is "Els Cargolins", the Snails.
