ARXX - Green Build System

“An Arxx foundation creates more, low cost, ready-to-use living space, so it’s easy to sell to homeowners. All people have to do is feel the difference. With Arxx you get warm and dry, with conventional you get cold and clammy! That’s why I built my new office on an Arxx foundation.” Mark Barstow, Homebuilder

Build more comfortable basements,
faster and easier than ever before

The #1 product with championship support

Arxx is the number one Insulated Concrete Wall System in North America. Arxx has the most production facilities, the widest network of distributors, and the best product. In fact, Arxx is the only Insulating Concrete Form (ICF) that provides a solid-to-solid attachment for any finishing material (like drywall, siding or brick ties). Our patented, exposed X-web is unique! Arxx is the one with the stripes. Plus, every time you build with Arxx, you get the best technical support in the industry: The Arxx Championship Support Team.

Build in extra comfort

An Arxx basement is more comfortable. It’s more comfortable than a concrete block basement. It’s more comfortable than regular poured concrete. Why? Because Arxx is the number one Insulated Concrete Wall System in North America. It is built with a reinforced concrete core sandwiched between two layers of expanded polystyrene foam insulation.

Arxx walls dramatically reduce drafts and “cold spots” compared to conventional basements. The two layers of Arxx foam insulation will also eliminate most basement humidity problems. The “thermal mass” of the concrete core stabilizes the temperature in your basement so that you get even comfort, all year round.
That’s the real payoff of an Arxx basement. You get more, ultra-comfortable living space from the very first day your home is built.

Build faster and better with Arxx

Arxx is the stay-in-place concrete form designed by builders, for builders. It is the complete wall building system. Arxx forms are lightweight, pre-assembled, and lock together. We provide the widest product selection in the industry, so you can build walls and foundations in any shape, size, or design you can imagine.

Arxx forms are 16¾" high, so six courses stack to a finished ceiling height of 8'1". Add another row of 12" high forms, and you get a 9'1" finished basement. It’s easy. You can protect the foundation with our peel-and-stick moisture barrier, or use our premium damp proofing, Arxx Maxx Foundation Wrap.
