    New Guide for Installation of Insulating Concrete Forms

    (What is a Work Item?)

    WK32076

    1. Scope

    This guide is intended to apply to the installation of Insulating Concrete Form (ICF) Systems that will act as permanent formwork for cast-in-place reinforced concrete beams; lintels; exterior and interior, above and below grade bearing and non-bearing walls; foundation; and retaining walls. The guide is restricted to ICF Systems that consists of molded expanded polystyrene (EPS) insulation panels that are connected by cross ties to form the ICF System with a resultant uniform monolithic concrete core.

    Building Officials, Designers and Contractors rely on accurate information to ensure the ICF systems, acting as the building envelop and structural system, are installed corrected and efficiently in order to perform their intended function. There are misconceptions in the ICF industry that internal consolidation is not required, that building paper is required and that flashing around penetrations is optional. There are many variations for installation that permit the use of extremely high slump concrete to be placed in the forms resulting in field failures due to excessive form pressures. There have been several instances where a very low slump concrete was placed without internal vibration resulting in concrete voids within the forms which in the most extreme circumstances can cause catastrophic failure of the structural system. Therefore once this guide is completed, building officials and regulators can be assured that an Insulated concrete form will be properly installed.
