Welcome and please allow me to introduce myself. My name is Jerry North.
I made the big move, relocated to Costa Rica and brought the modern construction technology called Insulating Concrete Form that would speed up the building process so an installer could be more efficient and build better quality structures in a less time.

Insulating concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid  thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete. The units lock together somewhat like Lego bricks and create a form for the structural walls or floors of a building. ICF construction has become commonplace for both low rise commercial and high performance residential construction as more stringent energy efficiency and natural disaster resistant building codes are adopted


Owners appreciate:

  • strong walls

  • disaster resistance and safety

  • mold, rot, mildew, and insect resistance (below grade can require termite protection)

  • sound-blocking ability

  • overall comfort

  • energy efficiency and resultant cost savings

Contractors and builders like:

  • fast, easy construction

  • flexibility

  • light weight for easy shipping and erection

  • compatibility with carpenter trades

  • ability to meet higher energy code mandates with less complicated construction

ICF Specialist built a 2200 sq. ft. home in one day with only a 13-man crew. We were able to complete the exterior walls, door, and window frames. The roof and concrete were installed on another day

Build your home with BuildBlock,
your complete ICF construction solution.

Congratulations on deciding to build your new home. BuildBlock Insulating Concrete Forms (ICFs) make concrete comfortable, quiet, safe, and energy-efficient. They survive natural disasters better than those built with traditional construction methods.

Traditional wood-frame construction can’t compare to the safety, permanence, resilience, and energy efficiency of walls built with insulating concrete forms.

As you begin formulating the plans for your new home, there seems to be no end to the number of choices you have to make. It’s natural to pour hours of time and effort into choosing the right paint, wall coverings, exterior finish and other aesthetics for your new home.


Before you begin, take some time to decide what will be inside those walls.


ICFs can be used to build any structure and nearly any design.

Residential Homes

ICFs are perfect to build your entire home. This provides the maximum energy efficiency and disaster resilience.

Foundations & Basements

ICFs are the fastest way to build basements and foundations. Solid insulation, strong walls, and worry-free construction.


Building multi-family structures, hotels, motels, and other high-density housing is fast and safer than any other building method.

Commercial Space

Freestanding office space, retail, and other structures all benefit from reduced lifecycle costs, maintenance, increased building safety and disaster resistance

Schools & Churches

BuildBlock ICFs deliver safe, comfortable and disaster resilient environment for schools, churches, hospitals, warehouse, and industrial buildings all benefit from ICF construction


Build faster, extend your pool season with an insulated pool without sacrificing design options


Complete ICF Solution

BuildBlock manufactures a complete ICF solution for projects of any size or complexity. Form sizes from 4″-12″+

Fully Reversible Form

BuildBlock ICFs are 100% reversible. BuildBlock ICFs always fit no matter which way you turn it.

Longer Corner Forms

BuildBlock 90° and 45° ICF corner blocks are 6″ longer on each leg than the industry standard. This reduces bracing requirements, prevents corner pullout and keeps walls straight and plumb.

Molded Tape Measure & Cut Lines

All BuildBlock ICFs have molded-in cut lines and numbered vertical cut lines. This makes it easy to get the right size each and every time.

The Tightest Block Interlock

The tight interlock pattern ensures the blocks fit snugly together, don’t float when poured, eliminating time-consuming zip ties and costly clips

6-Inch Web Spacing

All BuildBlock ICFs use webs spaced every 6-inches. This delivers more strength, straighter walls, and the strongest block on the market.

Dedicated Customer Service

BuildBlock provides customer and technical support resources for all types of users. Detailed installation manuals, how-to videos, engineering manuals, and more all to ensure your job is done right.

1″ Repeating Pattern & Lowest Waste

The lowest waste in the industry. The 1″ repeating pattern lets you cut off as little as 1″ and still be able to fully interlock the block in a wall. Use it all in your wall. Any scraps with at least one web can be integrated into the wall without sacrificing strength.

Patented High-Density Hard Attachment Points

Each web has two high-density 450lb.+ hard attachment points spaced every 8″ vertically to attached heavy cabinetry, bracing, and more directly to the ICF.

Embedded Studs

BuildBlock webs provide embedded studs anchored to the concrete 1/2″ below the block surface to prevent thermal bridging and webs showing through finishes such as stucco or plaster.

Truly Green & Sustainable Construction

BuildBlock ICFs build a structure that will last for generations, with reduced maintenance, and few additional costs. Build it once, build it for life.

Disaster Resilient

BuildBlock ICFs have a 4-hour fire rating, withstand winds in excess of 250mph, and nearly eliminates outside sound.


The BuildBlock ICF product family delivers a solution for ICF projects of any size or complexity. Build your home using the most energy-efficient and disaster resilient material on the market today. ICFs assemble faster with less hassle and cost than any other system.
