What is PermaWall?

PermaWall is the trade name for the Island Concrete manufacturing process of integrating 4000 psi concrete, steel studs, rebar, steel fasteners and polystyrene foam insulation into patented precast panels that are assembled to form the walls of a residence or commercial structure.

PermaWall Advantages:

Island Concrete Manufacturing Systems, LLC has the exclusive right to manufacture this patented wall panel system in the State of Hawaii.  Our first plant, located at the Hawaiian Cement Quarry in Central Maui, has the capacity to manufacture wall panels for five average size homes per week, with plans to expand to eight homes per week.

PermaWall is the Hawaii trade name for a building system developed in Florida.  It is time tested and widely accepted as the preferred building system in south Florida. This system brings many advantages to the Developer, Contractor and Homeowner: 

• The wall panels are delivered to the jobsite ready to install.  The exterior wall panels for an average one story 2,000 sq ft home, requires a single day to install and is ready for the installation of roof trusses and sheathing.
• An average single story home can be ready for roofing and Stucco in seven to ten days after the slab is poured.
• After the walls are installed and roof is framed and sheathed.  The building is ready for stucco allowing for the project to look as finished as it is.
• This system is jobsite friendly minimizing on site storage needs for lumber.
• This system has much less waste minimizing land fill fees and trucking charges.
• The walls have little to no cavities which minimize insect nesting and infiltration.
• The masonry walls are very durable and appropriate for our tropical environment.
• The panels are architecturally friendly, allowing for large door and window openings with no additional cost. 
• The system allows for the use of unskilled labor with skilled lead men providing layout and quality control.  This keeps the labor cost down while still providing employment opportunities in our community.  Something off shore pre-manufactured homes do not do.

Where can I find more information about your company and the manufacturing process? 

You can contact – Thomas Cook (tom@icms-maui.com) - with any immediate questions.

Who is ICMS?

Island Concrete Manufacturing System is a Maui owned and operated company. It was the vision of CEO Thomas Cook to bring a new method of concrete construction to Maui and address the need of better, affordable homes. Island Concrete has licensed its method of manufacturing wall panels from Royall Wall, Inc. of Florida. The Royall Wall concept was chosen because of its proven twenty-year record of building superior, hurricane-tested homes which are energy efficient, fire resistant and virtually termite proof.

 ICMS’s commitment is to Maui, Maui workers and Maui homeowners.

 Our goal to help address the affordable needs of Maui families by working with builders, architects and developers to build better, more affordable homes. 

What’s the cost per square foot?

Typically the wall panel cost is between $12.50 & $14.50/sf (for 8'-12' wall panels)

Our process is comparable in price to traditional wood stud construction. However, whereas wood framing can take up to five weeks or longer, PermaWall panels can be erected and fastened together on site in a single day, with roof trusses on and the roof enclosed inside of a week. The savings are generated via shorter overall construction time – potentially 30% shorter.  Better Quality Construction in less time - A good combination!

 How do I add on?  

Slab on grade lends itself to add-ons

 What about post and pier?

Not applicable; slab on grade only

I’ve heard there are mold problems with concrete block, what about your system?

Mold is a non-issue as there are no air cavities and the polystyrene foam will not absorb moisture.

Is this a good system for owner-builder?

Yes, purchase the shell and finish yourself.

What kind of warranty do you provide?

Ten-year limited structural warranty for the wall panels.
