Field trip to Jinja

On 10th July 2014 we went for an amazing and informative  trip to Jinja where we visited four interesting sites related to ISSB (click on the link for a mapped location):


Community centre by Newgate Technologies

The community centre consists of class rooms, volunteer sleeping quarters, meeting rooms and washrooms, all constructed using the ISSB technology:



Actogether Site

For the next step we visited Actogether. They are doing an impressive and innovative work and have developed a construction system based on prefabricated components that can easily be assembled, offering economic advantages in terms of construction cost.



  • Actogether has constructed a fermiculture Bio fill toilet. The construction entails; portioning (1m high, 1.2m wide), laying banana fiber, wire mesh and banana fiber again, laying a net, placing manure, adding water, and placing worms that feed on the human waste. The number of worms depends on the number of users. However, 7 kilos of worms decompose waste of 15 people per day.


Community toilet

We visited a community toilet for the people that work in a market place in one of the suburbs of Jinja town. It is run by the people within the community. The toilet was funded by the World Bank and built by Actogether using ISSB for most part. However, other materials were also used like concrete,ladies, T beams…

HYT headquarters

Finally we went to the HYT Headquarters. HYT mainly train the community on the use of the ISSB’s technology.


After HYT Headquarters we left Jinja and came back to Kampala…



First Community ISSB Training

The PECTIS project team organised the first Interlocking Stabilised Soil Block pressing training session from 28th June to 4th July. Ten young men from Yoka, Kanyogoga, and Tibaleka zones of Namuwongo received theoretical and practical instruction on the appropriate mix of ingredients, the use of the machine (“Makiga”-type fabricated in Kenya), and the stacking and curing of the blocks. In addition, the trainees were briefed on the objectives of the PECTIS project and the future activities (construction of communal infrastructure, entrepreneurial and environmental management trainings). During the week-long training, over 300 blocks were pressed and should be ready to use in construction within 10 days.

At the end, the trainees were congratulated by their trainer, Pastor Ben Prince Tendo, and awarded certificates of attendance. The PECTIS team intends to invite the most motivated trainees to form efficient block-pressing teams ready to produce sufficient material for upcoming construction projects.

1st day of making interlocking brick

Benjamin, 2nd year student of Environmental Design at the Faculty of Built Environment, reflects on the experience of pressing bricks:

On 6th june,with the arrival of the machine, we set out to make the compressed earth interlocking brick so that we could become familiar with how the bricks are made and the mix proportions required to make the brick.  61 bricks for a start, that wasn’t so bad!

First Blocks Pressed

The students and lecturers spent the morning assembling the machine, sifting the sand and soil, and pressing the first 16 ISSB blocks.
