Poured Concrete Wall Planning

Poured concrete walls — for basements, foundations, and stem walls — are among the most concrete-intensive residential projects. An 8-inch thick wall uses about 0.2 cubic yards per linear foot at 8 feet tall. A 40-foot basement wall needs nearly 8 cubic yards — this is always a ready-mix truck job.

Poured walls require engineered forms — either reusable aluminum forms (contractor equipment) or plywood forms built on site. Forms must withstand the hydrostatic pressure of wet concrete, which is substantial at full wall height. This is not a DIY project for most homeowners.
