Good result today with the new method for making imprints in moist dirt. These imprints are made with the also renewed version of the mold for the big slabs (see info). This new system uses four different parts: the two decorated slabs, a removable cover for each slab, a gutter. into which the two Bathroom floor slabs drain and three thin concrete separating slabs. These three separators are kept in a vertical position at some distance by masoned walls in between, thus making two separated cellars. The middle separator carries the gutter. the outer separators carry the outer edge of the bathroom floor slabs.
The removable cover is part of the bathroom floor slab. It can be taken out to empty the cellar when its content has been left to compost for about half a year. Extensive experience in Vietnam indicates this composting system works well and produces safe compost.

I hope to use this new system in a pilot guided by HSHC in Nairobi within a month from now. In that same time span a lot more work has to be finished as well as a start has to be made with the use of the new workshop in Maastricht.
Today I got assistance from Tom Groenveld, student forestry at Larenstein. Tom plans to make a study trip to Kenya this summer and most probably he will contact HSHC in Nairobi. He wanted to be instructed in the use of the mold to make imprints in the dirt. The pictures show: 1) preparing the site, 2) filling and compacting the mold with wet soil, 3) turning over the filled mold, 4) compacting an dirt ridge around the mold, 5) lifting the mold carefully off and finally looking happily at the accurate copy thus achieved.
