Abstract
Ferrocement structures and the method for producing them comprising: providing a load-bearing framework, covering the framework with a strong flexible sheet-like material and then a flexible metal reinforcing material, and applying cement mortar thereover to cover the reinforcing material. The framework can be made of easily fabricated wooden ribs.
Claims10
An enclosure comprising:
- a. a load-bearing framework defining the shape of said enclosure, at least a portion of said framework having a convex configuration;
- b. at least one layer of moisture-impermeable flexible sheet-like material having an inside surface and an outside surface disposed over and supported by said framework, portions of said inside surface being in contact with said framework;
- and
- c. a layer of cured cement mortar having reinforcing means therein disposed over and in contact with the outside surface of said sheet-like material, said reinforcing means comprising at least two layers of wire mesh embedded in said cement.

A method for constructing an enclosure which comprises the steps of:
- a. providing a load-bearing framework defining the shape of said enclosure, at least a portion of said framework having a convex configuration;
- b. applying over said framework at least one layer of flexible sheet-like material having an inside surface and an outside surface so that portions of said inside surface are in contact with said framework and said sheet-like material conforms to the shape of said framework, said sheet-like material having sufficient tear strength and impermeability to moisture to support the cement mortar mixture applied in step (d) hereinbelow;
- c. applying over the outside surface of said flexible sheet-like material at least two layers of flexible wire mesh which conforms to the shape of said sheet-like material and said framework;
- and
- d. applying over said sheet-like material and over and around said wire mesh a wet cement mortar mixture in sufficient quantity to provide a substantially void-free layer of wet cement mortar which completely covers said wire mesh.
