We are doing preparatory work for our second phase of CEB construction – Inga’s House. Over the winter, we built the first CEB structure – our workshop addition. We’re moving on to building under optimal conditions – dry summertime and improved CEB press Prototype 2.
Here we begin with initial site analysis and soil samples:
And here is the soil sample analysis result after 3 days of settling:
Result II comes from 2 feet below ground level on the Western part of the land parcel, marked by the white circle on the map. The soil fraction appears to be about 40% clay on top, a small fraction (<10%) of silt, and the rest is large-grained sand. This appears suitable for CEB constuction, if the desired clay fraction is 30-40% of the soil.
Result 4 (from 2 feet down in the northern part of our land parcel) appears to be nearly 100% clay, and we would have to add sand to prevent excessive cracking.
Here is a further description of the site and elevations. You can also access the Google map here.
