Commercial / Industrial

A great alternative to tilt panel construction, Insulated Concrete Forms (ICFs) are revolutionizing modern construction and rapidly changing the way we build homes, commercial buildings and institutional structures. Amvic Building System is leading this revolution by providing the highest quality and highest performance ICF on the market.

Amvic ICFs are designed with 2.5 inches of 1.5lb/cf density foam on both sides of a form containing 8 uniquely designed polypropylene webs. The webs are spaced 6 inches on center compared to 8 inches on center in most competing products. Amvic webs also use more raw material than other ICF blocks, which allows for a 198 lb pull out strength for drywall screws and makes the form more rigid. The webs also have a uniquely designed rebar holding system that reduces the need for tie-downs and places the rebar at the most effective locations to ensure superior structural strength. The resulting strength of the forms eliminates the chance of blowouts when concrete is poured. Additionally, in 2005 a unique new corner reinforcement was added further increasing the strength of the forms.

Since Amvic ICFs weigh less than 10 lbs, the need for heavy equipment such as forklifts, cranes, lift boxes and cement mixers is lessened, thereby reducing some of the ongoing soft costs of construction. The primary tools needed on an ICF jobsite are handsaws, foam guns, portable rebar cutters and bracing. It is not necessary to have electrical service in most cases.

One of the most expensive outlays on a commercial project is labor. The design of the Amvic ICF wall is such that structure, insulation, vapor barrier, sound barrier and attachments for drywall and exterior siding are all included in one step reducing labor requirements and construction delays. One experienced ICF installation crew is all that is needed to finish the foundation and/or exterior walls in a matter of days instead of weeks that it may take traditional framers. Amvic blocks are reversible and are designed to grip re-bar so that no tying is needed. FormLock technology reduces the need for gluing or tying blocks, making Amvic ICFs the most user friendly blocks on the market.

Recent tests conducted in 2003 and 2005 by the United States Military andreported in ICF Builder Magazine demonstrate the incredible strength of ICF structures. Even at the closest blast distance of only 6 feet away, using 50 pounds of military-grade TNT, producing a blast and ball of fire approximately 200 feet wide and 100 feet tall and generating a force 10 times the weight of the 10' X 10' box, the ICF walls survived the explosion with only small cracks. There was no deflection, spalling or structural damage to the concrete.

When compared to tilt panel construction, insulated concrete forms offer a host of advantages. Additionally, site space is freed up since the walls are assembled and poured while standing. This eliminates the use of slab space for the casting of the tilt panels or the need for dedicated pouring beds.

ICF walls do not require the use of cranes. They do not need any welding, grouting or caulking. Interior cavity walls are not needed for insulation or utility installation. Waterproofing is not necessary, and any exterior finish may be applied, with stucco systems being adhered directly on the expanded polystyrene panels. And, the speed of construction is increased by using ICFs. All these factors figure in to significant project savings with regards to time and labor for spaces that will be occupied after construction.

Tilt wall integrity is largely determined by the roofing system. In the event of a large windstorm or fire event, the chance of roof damage presents the very real scenario of building collapse. ICF walls are not reliant on the roof structure and will very likely remain standing after a catastrophic roof failure.

Jobsite safety is a serious topic. By using ICFs, the need for cranes on the jobsite is reduced by a large factor. The individual ICF forms weigh less than 10 pounds each, reducing the risk of worker injury. The number of different subcontractors is also lowered, resulting in fewer people needed for the project.

Long a popular construction method, concrete masonry units (CMUs), have a new rival. When being considered for occupied or conditioned spaces, ICF construction is faster, stronger and more cost-effective than CMU. CMU construction requires additional moisture proofing, stud cavity walls and insulation. All of these are steps that utilize separate sub contractors, slowing the project progress. ICFs combine all these steps into on product, which can greatly reduce construction time. Scaffolding requirements can be reduced, which will save rental cost and increase jobsite safety.

CMU is also much more labor instensive to install with mortar cold joints on four sides of every unit. ICF construction can be achieved with no cold joints, making for a decidedly stronger monolithic wall segment. Mortar joints provide the opportunity for cracking, and stucco finishes often reveal the joints over time. The expanded polystyrene panels of an ICF provide the perfect substrate for any stucco or EIFS system.

In a nutshell, when making an apples-to-apples comparison including all the construction steps to complete a wall section, ICF stands above others as the modern construction method of choice.
