Volunteer experience from a week of eco-toilet building workshops.
During my time in Central America I have seen a real variety of earth architecture from pristine superadobe earth domes to some really basic mud huts and after some research I found out why, traditional building methods such as Bajareque have been used for the last 700 years and it is only relatively recently that this has been replaced largely by cement construction. With a view to eventually building my own house I set about finding ways to learn some of these old techniques and eventually was pointed in the direction of Tribe LAB and more specifically the earth architecture workshops.
Tribe LAB are in the process of designing a school out of local, planet-friendly resources using traditional, people-friendly building techniques and the workshops were a showcase of the different skills and materials that would be used for the project. However due to their long term close work with families and the community instead of building solely for demonstration purposes Tribe LAB chose to build an eco toilet for a family whose current toilet situation rivals that of a festival on Sunday afternoon. The workshops were to run in the mornings over the space of a week and covered everything from cutting the first piece of wood to its christening.
Day one was an introduction to the organisation, the school, the family and the toilet design. From the moment we arrived at the school it was clear that the team had a great working relationship with the current school and community, they’ve been working for a number of months to design the new school so that it meets, and hopefully exceeds, the needs of these super cute, under fed children. Why do they need a new school? Well the primary school was destroyed by a landslide and since then they have been sharing the space with the middle school whose students now only have access to their own school after 12.30 pm each day. In the current situation different ages are sharing classrooms, a lot of children aren’t getting enough to eat, and the concrete playground has as much shade as a desert island. The new school has been designed to make the best possible use of the space available, incorporating a garden into the design as well as running nutrition programs for children that need help. unfortunately there are quite a number of them. The majority of families support themselves by farming coffee, corn, beans, fruits and vegetables, the average farmer earns 480Q (63$US / £40) per month.
We saw a few of the classrooms and the resources they were working with or, more accurately, working without and the Prepa kids (preschool/kindergarten age) hit us with the cutest, giggliest renditions of their favourite tunes, complete with moves, that were all met with great applause. After the mini tour of the school we carried all the materials down to the house where the eco toilet was to be built. We took the pile of materials from outside the school and zig-zagged between the houses which is a fun task with a massive piece of bamboo, like a curious mix of jousting and Pac Man. We did make it to the the house, or now build site and
We were introduced to the family, the mother Anna, Spanish is her second language, after Tzutujil, wears beautiful, traditional clothes called ‘trajes’, makes amazing handwoven material to sell and smiles a lot, a habit she has passed onto each of her eight children. The younger children initially showed caution but to be fair to them we were 25 random new people, carrying large pieces of bamboo, power tools and pickaxes, we were clearly up to something! The father was only met in passing as he was working but seemed a friendly guy when he was around.
The eco toilet was explained and the design shown around so that we all had a picture in our head of what we were all aiming for! We saw where the eco toilet was to go and broke into two groups, one to cut the bamboo to the correct lengths and create the ‘fish mouth’ joints that are necessary in bamboo construction and another group to dig the all important hole. The sun cranked up the heat as we took turns to dig and learn about the process of bamboo construction and before we knew it the hole was big enough to fit a laughing group of children and the bamboo had been finely prepared ready for the next day’s activities. We packed away our gear and and left ready to get stuck in again tomorrow.
Less people came for day two, possibly due the heat, travel plans or maybe they hated the children, my guess goes with the heat or people continuing on with their adventures. Day two was set to be a more hands on day and after a brief recap of the previous days activities we set to work building the bamboo structure for the eco toilet. The earth from yesterday’s impressive hole digging was to be used for the bajareque walls tomorrow. Bajareque is similar to the european system of wattle and daub, you make the wall frame out of small strips of wood and then fill it with premixed wet, sticky earth. This needs to be prepared the day before use so while a crew got to work on getting the frame of the structure up another crew sorted through the available earth for the decent quality clay soil needed for the walls and then it was shoes off to get stuck in with mixing it all. Tired, sunkissed and quite muddy some people headed off to the comedor to get some much needed tortillas while other went to jump into beautiful Lake Atitlan.
The third and fourth workshops were what I personally had been excited for, making the Bajareque walls. After seeing the different earth construction styles being used in Guatemala it was amazing watching walls come up out of the earth we had previously been standing on. We took the prepared earth and made it into compact balls for the wall makers to then fit in between the wooden lattice and compress down. It is a very fun process that got everyone involved and soon we had ball of mud flying around between people not because we were being in any way childish ,of course, it was just the most convenient way of passing big lumps of mud. Parts of the roof were also added which made it definitely look more like a proper structure and gave us a clue as to what the final completed thing will look like. One thing that has struck me about all the different natural building styles I have seen put into practice is their simplicity. Natural building techniques like this have been used for thousands of years and are not complicated, this really appeals to me and the day flew by in a storm of mud, laughs and sunshine.
Saturday morning was quiet due, possibly, to San Pedro’s very active nightlife over the weekends and down to the fact that the Tribe LAB crew had headed down to La Barona to speak to the community and evaluate what kind of help they can provide. La Barona is a small Guatemalan village near the El Salvador border and was hit by a series of crazy high waves from the Pacific Ocean nearly three weeks ago. A number of families lost their homes completely while many others are still as yet not able to return.
We got to work on the walls structure. Small pieces of cane tied to the main bamboo structure to provide privacy and and extra support to the back wall. We measured and cut the corn canes we were using, and then set about tying it with a secure but tricky series of little loops. The children, aged from two upwards, helped us and were hilarious and the fiddly loops soon made more sense and about the time they did we finished the back wall and it was time for lunch!
After a couple of days rest and some dedicated chill time down by the lake we regrouped on Tuesday to finish this lovely family’s eco toilet. We had the materials and extra hands, happy to help, the bamboosito walls were finished by a team of budding cord-loopers while limestone was prepared to finish the outside walls nicely, limestone and water mixed into a plaster and once it was finished I must say it did look mighty tidy. Then we all got involved in the making of a very curious mix consisting of clay earth, horse manure, fermented prickly pear cactus or Nixteng and water. The curious part was the prickly pear cactus that had been fermenting secretly behind the scenes, the other ingredients were obvious about what they were, it had the texture of glue and was a similar looking to the ooze from Ninja Turtles or Flubber which made me chuckle, just imagine the possibilities. The ooze in the case will not turn the toilet into a ninja but is actually an old traditional way to waterproof and protect the inside walls to avoid dust coming from the walls, a common thing in earth structures and so the earth plaster was ready to be applied.
All was heading for completion, roof on, walls getting their final coat of plaster when a storm rolled over a looked set to get us very wet. We’ve moved into rainy season here and when it rains it doesn’t drip, drizzle or spit, it really rains in quantity, so we tidied up the materials and agreed that a few of us will come back tomorrow to add the finishing touches to the toilet, like an actual toilet. At the moment they have a really fancy shed with a large hole in the floor but this is Guatemala and if anything was ever finished on time it would be an enormous shock. Hasta mañana!
