Prefab Ferrocement Kits

Easy & Fast
Sustainable & Durable

Prefab Ferrocement Kits

What is the am-cor System? It's a method of combining:

  • Ferrocement construction, with
  • Lightweight Framing Panels,

Into factory-made, Prefab building Kits.

Even better, not only are they easy & fast to put up, with no constuction skill required, but also provide sustainable & durable shelter from: hurricanes, tornadoes, earthquakes, bullets, and more.

What's Ferrocement?

Fer­ro­ce­ment = highly re­in­forced, dense & thin steel & ce­ment shells; ori­gin­ally used for boat hulls.

The am-cor Sys­tem™ is a prefabricated, modern Ferrocement con­struc­tion sys­tem, fea­tur­ing:

  • True com­pos­ite, in­teg­rated steel & ce­ment struc­tures
  • Unibody, seam­less, ex­ter­i­or stress-skins
  • High flex­ib­il­ity & ad­apt­ab­il­ity
  • High strength-to-weight ra­tio

Our standardized building panels are fabricated in a quality-controlled factory-setting. This simplifies: permit approval, shipping, and on-site assembly.

Inventor's Story

“We of­fer an ad­vanced & green solu­tion to today’s con­struc­tion in­dustry: Stand­ard con­struc­tion is just too ex­pens­ive, time-con­sum­ing, and un­sus­tain­able. Worst of all it doesn't pro­tect people from nat­ur­al dis­as­ters, cli­mate change, nor high main­ten­ance & util­ity bills. Our Fer­ro­ce­ment am-cor Sys­tem is the an­swer.”

- An­gus W. Mac­don­ald, In­vent­or & CEO

The am-cor Sys­tem™ is a simple, fast, af­ford­able way to build green & sus­tain­able build­ings. Ar­chi­tect Angus W. Macdonald in­ven­ted and pat­en­ted the am-cor Uni­fied Steel & Ce­ment Struc­tur­al Sys­tem™ after search­ing for a bet­ter al­tern­at­ive to stand­ard con­struc­tion meth­ods. He wanted something that was simple to con­struct, quick to erect, cheap to build, and above all, beau­ti­ful, dur­able and sus­tain­able.

Why Use am-cor



  • Save 15-20% over stand­ard build­ing con­struc­tion costs
  • Com­plete in 2/3 time of stand­ard con­struc­tion
  • Save 10% an­nu­ally on stand­ard build­ing op­er­a­tion costs


  • Flood-res­ist­ant
  • Ex­tremely low main­ten­ance over build­ing’s life­time
  • No rust, no de­teri­or­a­tion


  • Sus­tain­ab­il­ity: ap­prox­im­ately 70% smal­ler car­bon foot­print
  • Far less ma­ter­i­al used than stand­ard con­struc­tion:
    • 20% less steel
    • 80% less ce­ment

Tried & True

The am-cor System is a proven system: am-cor structures have weathered tornadoes in USA’s Tornado Alley, hurricanes in the Caribbean, and floods on Virginia’s Eastern Shore. Our building shells are internationally code compliant, and have been approved by the US Army Corps of Engineers for construction in storm surge areas. The first structure was built in 1996, with numerous ferrocement homes and other buildings types worldwide. Its Ferrocement construction has withstood the test of time, with zero structural maintenance & minimal exterior maintenance.
