The ideal base for concrete is even, firm, and permeable to encourage drainage. Depending on your project's weight requirements, a combination of gravel, sand, or other aggregates is best. While you can technically pour concrete over grass, dirt, or an old piece of concrete, you risk threatening the concrete's stability.

Most of the time, you or your contractor will spray the concrete form and framework with a release agent or oil to prevent sticking. This is common practice with wood and steel forms. For insulated concrete forms, the styrofoam formwork often remains in place after construction, so you don’t need to treat it beforehand. Foam concrete forms made out of melamine also may not need treatment beforehand, as the material naturally won’t stick to the concrete after it’s cured.

Installation typically takes 1-2 weeks, depending on the wall’s size and site conditions.

Concrete walls last anywhere from 30 to 100 years. In many cases, concrete walls will last longer with proper support and ongoing maintenance. Some concrete foundations, for example, could last up to two centuries when properly maintained. Toward the end of its life span, however, it's critical to have a structural engineer examine the concrete wall for potential signs of decay.
