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.
