Thanks Steve. Nice bit of marketing but you avoided my question again!
Now lets get past the marketing and look at the product you're promoting because its really niggling me when you make these claims as if they are new. Ferrocement is centuries old.
You can control your working environment and gauge your materials as much as you want. But you have no control over the weather which plays a significant part in the curing process of ferrocement.
For the uneducated on ferrocement:
To construct something from ferrocement, someone starts by creating a frame of wire mesh. Chicken wire is a common choice, but any sort of metallic mesh will work. The mesh is often layered, creating a matrix. Next, a mixture of cement, sand, and water is spread over the frame, typically very thinly, and then the ferrocement structure is allowed to cure; most people keep the ferrocement moist as it sets. The curing time varies, but can exceed a month in some climates and situations. At the end of the curing period, the resulting structure is quite strong and very solid, despite the fact that the walls are very thin.
Therefore, unless you have weather control tools. (This would be worth putting on youtube). Every individual ferrocement roof will cure differently depending on the climate when it was installed and the climate in the following month whilst the material cures. How do you keep a roof moist for 1 month?
How can you guarantee this consistent performance?
Goes back to my original point of installing membranes like EPDM which are manufactured in factory controlled conditions and can guarantee performance.
