Researching ICFs

A good place to start your search for information about ICFs is the Insulating Concrete Form Association (1807 Glenview Rd., Suite 203, Glenview, IL 60025; 847/657-9730; They publish a list of member manufacturers, distributors, contractors by state, and design professionals, all of whom are linked to their website. The website also sells books, publishes a calendar of industry-related events, and promotes an annual convention.

While you're surfing, check out, edited by Pieter VanderWerf, a well-regarded ICF expert. Here you'll find message boards, product reviews written by end users, and a search engine that will direct you to information on concrete admixtures, waterproofing techniques, and ICF contractors.

The Portland Cement Association also maintains a website with information on ICFs, at

Some manufacturers will provide you with learn-before-you-buy construction manuals and videos, in addition to their product literature.

When evaluating these resources, questions to keep in mind include: How are the ICFs distributed? Is there a local supplier, or will freight charges be added to the order? Is there a list of contractors in your area who are familiar with ICFs? Is the manufacturer able to provide help with basic engineering calculations, such as the specifications for placement and size of rebar? What type of technical assistance is available? You will also need to find a local ready-mix company with a pumper operator who has had experience pumping ICF foundations.
