“BuildBlock Insulating Concrete Forms (ICFs) are the strongest and most energy-efficient building material available today. ICFs are used to build homes, schools, churches, and other commercial buildings. Choosing ICFs for your next construction project means saving money every month and feeling secure in your home.”

The BuildRadius Wall & Pool ICF Radius Blocks Family


BuildRadius is a family of radius forms for use in ICF walls and pool construction. The BuildRadius forms create 2’, 4’, 8’, 12’, 16’, and 20’ arcs. Each of these blocks interlocks into any BuildBlock 6” product line and uses the standard BuildBlock webs. Available in 6” widths initially, these forms are designed to ease construction of energy-efficient ICF pools, southwest style homes, bay windows, circular staircases, and provide options when designing unique areas in ICF homes.

ICF pools are growing in popularity because of increased energy efficiency which decreases costs for heating pools and extends the pool season. The benefits apply to both residential and commercial pools. Substantial heat is lost through the sides and floor of pools and ICFs deliver insulation performance. Additionally ICF pools can be built very quickly and efficiently reducing the number of materials, skilled labor, and finishing products required.

“We have been evaluating the needs of our distributors and direct customers who are requesting new and innovative designs in their projects and simple ways to build pools and other structures.” says Mike Garrett, BuildBlock CEO. “We developed BuildRaidus using standard arcs to ensure the forms interlocked correctly using the same strong BuildBlock connections and webs as our other forms. This should deliver exceptional performance, simplified bracing and superb results. This is the fifth new product we have introduced this year with more to come this summer.”
