ICF Foundation Installation

Missourians are no stranger to tornadoes and harsh weather conditions. Over the years, insulated concrete foundations have grown increasingly popular in Missouri for their strength, durability, and resistance.

Insulated Concrete Foundations protect against the following

  • Disasters
  • Extreme hot & cold temperatures
  • Moisture
  • Termites
  • Fire

Insulated concrete foundations vs. poured concrete foundations: Which is right for you?

Insulated concrete foundations add more energy efficiency to your property than a traditional poured concrete foundation. No need for interior framework or exterior sheeting. No need to install a larger furnace or AC unit. With an insulated concrete foundation, you can save up to 30-50% on your heating and cooling bills.

Double-sided and steel-reinforced insulated concrete foundations make it easier to control the climate and mitigate sound pollution. They’re highly resistant to heat flow, cracking, and moisture intrusion, all while withstanding tornadoes and hurricane-strength winds.

Plus, ICF blocks make it possible to build your new home faster and more efficiently, cut down on construction time, and save money.
