When Frank Froelich of Hinton, Iowa poured a 26-by-60-foot concrete patio last summer, he wanted to use products that would keep the concrete from heaving and cracking in a couple of years. 

He visited with LiteForm Technologies of South Sioux City, and purchased the FlexxBoard25 and Helix products. FlexxBoard25 is a rigid foam board insulation specifically designed for use under concrete. 

“The rigid foam board insulation keeps the frost away from the concrete and keeps it from lifting the concrete. Even with this cold weather, it hasn’t moved a bit,” said Froelich, who started Fremont Tire in 1976 and is now retired. 

Construction grade foam insulation from LiteForm can be used for new or replacement sidewalks, driveways or patios. The insulating board also works for insulating uninsulated spaces, and for shallow frost-protected foundations.

Helix is mixed in with the concrete as a replacement for rebar to increase its strength and durability. Applications for Helix include, but are not limited to: structural foundations, footings, slabs, walls, shotcrete and precast products.

Using LiteForm insulated concrete forms  for the walls of the new CENEX convenience store/gas station in Jackson, Neb., will result in a sturdier building and help with sound control, said Murray White, general contractor for the building project.

“The building will be well insulated, so you won’t hear all of the traffic driving by. And if it is going to catch a lot of wind, it will be much stronger than a wood frame structure,” said White.

In addition, the new 7,000-square-foot CENEX station will have no intermediate walls inside, so it needed to have concrete exterior walls to pass code, he said. The building will have an asphalt shake roof and a stucco finish over the walls. Part of the exterior will be covered in stone.

Don Prenger of Prenger Construction, who uses LiteForm almost exclusively for his construction projects, installed the FlexxBlock insulated concrete forms.

White said the staff at LiteForm was very helpful during the process.

“They were very good. They stopped out almost daily to see if we needed something,” he said.

Construction started in May. The new CENEX station is one-third of the way completed and an October opening date is planned.

“It will be more like a truck stop. It will have diesel pumps and be open 24 hours. The building will feature a full kitchen offering food. There will be a walk-in beer cooler. It will be a nice building,” he said.
