Use biodegradable form-release agents
Release agents made with vegetable oil are safer
The petroleum-based release oil that's typically sprayed on concrete forms can seep into the ground around foundations. Some may remain on the concrete, where it can contribute to indoor air pollution. A new generation of form-release agents are made from vegetable oils, which degrade naturally and are less harmful in indoor air. An alternative to removable concrete forms are insulated concrete forms (ICFs), which are made from polystyrene insulation. They remain in place and provide insulation on both the interior and the exterior of the foundation wall.
