Hello All,

I was looking at Ferrocement videos on youtube and came across this unique and very creative, FC home in New Zealand: https://www.youtube.com/watch?v=uqfnka7O8_g

It always amazes me to see the unique, artistic expression and creative ideas that can and are being expressed in FC. Be sure and check out the hot tub perched atop the second story dome.

Hi All'

This is the third and last installment on the floating solar project. I recently received a photo of the build site after the flood. All three mother platforms are now floating as intended in the dam basin. Given the very sloppy construction  , bad sand,  wet mix , lack of constant curing and total lack of supervision by the upper management it's a minor miracle it went so well. It is a great example of the forgiveness of the FC/ LFC construction method.

I came bask to the US after six weeks , it seemed a very long time living through it but looking back now several months some of the horrors have faded from memory. I was unable to fully impart good construction practises but some improvements were achieved. I was never paid the bulk of the promised fee for my time despite repeated assurances. The CEO of the company is a charming fellow but lacked the strength to lead his team to produce a quality product.

I am not sure if the 17 platforms were ever built to complete the project, certainly they were not within the contract period of November 20016. In spite of the difficulties and lack of payment I am proud of what was accomplished  and while I wont be going back I am glad I took the trip.

Hi Chris,
I took a look at your web site, really great stuff. Have you considered adding gray water to your storage systems ? Lots of good water going down the drain that could be used on plants?

Also I liked the water gauge on top of the tanks, can you tell us how they work and perhaps a description of how you make your tanks.

Hi, my name is Chris Meador, I own and operate Permasystems - a company's whose mission is to design, build, and supply low-impact, perennial and functional structures - including those made out of ferrocement. I took Paul Sarnstrom’s FC/LFC course in 2014 and it changed my life! Currently Permasystems mostly builds 300 gallon LFC cisterns, primarily for rainwater harvesting storage. I have been doing this for 2 years. I have also built LFC planter box - type things.

My website is http://www.Permasystems.org

When I was young I watched my “godfather” build things with ferrocement: planters, retaining walls, covers, tables, and amazing art, like a mountain lion. This planted the seed of LFC in me. 

I am interested in building the following out of FC/LFC:
- Roof
- Home/shed/structure
- Hot tub
- Much larger water tanks and imitation rock tanks
- Retaining walls
- Tables
- And much more!

I will post pictures and descriptions of my work in appropriate parts of this site. Here is a little more info:

This link provides a little more information about how I build the tanks http://www.Permasystems.org/laminated-ferrocement.html

Hi Minitto,

Simple answer, LFC of FC will save you a fortune over wood IF your design takes advantage of the system. By that I mean keeping the labor cost low by NOT spending lots of time doing weird shapes and forms so it look like something from a Hobbit movie. The materials in LFC will be way cheaper , and better , than any conventional system but the final cost as Paul said can get out of hand when you factor in man power.

A wood living roof sounds like a rot problem waiting to happen.

I am is LA county and if you need some advice on the matter give me a call 818 693 1697

Hi Crasch

My e mail is bradfordsimms@gmail.com, I have been a big fan of the Seasteader project and would love to help.

I will do a final post on the India project soon but bottom line " It floated"

Anyone know how I can get in touch with Upston?  I'm a volunteer with The Seasteading Institute, assisting with the The Floating Island Project:


I want to reach him to inquire about hiring him to help with a sub-project related to the FIP.  However, the forum software gives me an error when I click on his name to message him directly.    Thanks in advance for any assistance!

Thanks for posting this story, Upston!  Would love to hear more about it.  How did it turn out?

Hello Paul,

Regarding your basic roof design and if it should be wood or a cementitious material like concrete [RC] or Ferrocement [FC]: Earth sheltered, underground and living roofs have been successfully designed and constructed using wood as well as by using concrete and/or Ferrocement. Given that both wooden and cementitious materials will work the factors come down to cost, availability and your experience and confidence in working with a particular material.

If using FC or RC the thermal coefficients are the same as for the concrete used in your ICF or CMU units. In other words both the roof and the walls will have approximately the same thermal coefficients so expansion and contraction will not cause problems between the walls and the roof. Wood has a markedly different thermal coefficient from the steel and cementitious materials used in RC or FC. It can certainly be done but a different design must be arrived at to connect the roof to the walls and still allow them to 'float' independently as they expand and contract at different rates.

Regarding your question on which would be cheaper: Overall cost factors are based on materials cost but skilled labor will most likely be a greater cost than materials alone. In addition to materials cost and labor costs, the expected life-cycle of a particular system should be taken into account. In this example of an earth covered roof, presuming good design, quality materials and proper procedures were followed I would expect the life cycle to be similar. Based on the roof being covered with a deep layer of soil and the protection that soil gives, I would expect a properly designed and constructed, earth sheltered wooden roof should last quite awhile.
