Earthbags are a great idea for building raised garden bed surrounds because of their simplicity and their strength.
Recently Nick led a community workshop to transform a townhouse patio into an edible landscape, with earthbag surrounds for a set of bathtub wicking beds…
The patio before the install
Wicking bed bathtubs arrive! And patio is cleared and ready for action.
Our mate Charlie from Ecolicious helped out, delivering a truckfull of earth left over after a pond had been dug for one of his current aquaponics installs…
Monique (patio owner) doing some prep by compacting the earth prior to the workshop…
The plan – a series of bathtub wicking beds, surrounded and supported by earthbag walls…
‘Tamping’ down the earth to compact it prior to laying the bags, using our trusty earthbag tampers…
Filling the first bag!
Nick did hourly explanations of the process to the rolling roster of workshoppers throughout the day…
Tamping the bags flat…
First course laid, with barbed wire on top to improve tensile strength between layers of earthbags…
Laying wire on top of the second course of earthbags…
Cuppa time!
Towards the end the daylight ended, but a stalwart crew pressed on to finish the job…
Fabulous workshoppers looking forward to pizza and beer appearing shortly after a big day…
The result the next day – raised bed walls are finished and sturdy, with bathtubs installed!
Following on from this workshop, Monique will be hard at it in the coming weeks installing the innards of her bathtub wicking beds, and planting up her garden! She’ll also need to render the outside of the bags to protect them long term, using some sort of waterproof render. Options for this include:
Hessian-crete – hessian bags dipped in a rapid-set cement slurry and then draped over the walls- we’ve never tried this, but we rekon it would work well, and use the least cement! > link to Burlap-crete project
Ferrocement (often used in rendering outside earthbag installations) – ferrocement garden beds in the Milkwood Farm kitchen garden, and an earthbag seat project using ferrocement
Hempcrete – with a stiff mix, this might be a possibility… Hempcrete Australia website

Many thanks to everyone who contributed their time and efforts towards a great day, from all across Sydney – it was great to have you all there! Thanks particularly to those stalwarts who stayed on past 4pm to finish the job… you all rock!
This workshop was held as part of the celebrations for International Permaculture Day, which is all about getting involved in community resilience, whether by touring a garden, attending a picnic or getting grubby whacking great long bags of earth…
Lastly a note from Monique, whose patio this all occurred in: Thanks to Nick Ritar from Milkwood Permaculture for facilitating this amazing Earthbag building workshop; Charlie Bacon from Ecolicious (aquaponics systems, ponds and organic gardens) for helping me move over a tonne of clay; Peter Wright from Gaia Gardens for picking up and delivering 3 bathtubs from Kimbriki for me at very short notice + Kirsten Bradley for co-creating the idea of having a workshop on National Permaculture Day (and volunteering her husband to run it).
And thanks to all the fabulous volunteers / participants throughout the day : Adriana, Andre A., Andrea C., Andrea Pape, Craig Duckmanton, Daniel C., Diana E., Diana Watson, Dianne M., Ian H, Joy J., Julio B., Kat T., Linda S., Marcelo B., Margo C., Martha M (in Sydney for a wedding for a few days, and who’s partner demanded that she pop in to see what was going on so she could tell him all about it when she got back to Turkey… love it!), Michael C., Mike M., Misa Z., Monika B., Monique Unger, Nathan C., Peter W., Phillip E., Robin S., Sarah B. & Stu R. Awesome job everyone! Thank you!
A small sample of the many fabulous folks who attended the workshop – thanks everyone!
