At the start of a concrete project the concrete is semi-solid and can be manipulated to assume almost any shape. The concrete hardens, the form is removed, and the finished project maintains the shape of the form. Use concrete forms to create a solid barrier to hold the concrete in place. Find wide selection of concrete forms at Moon Decorative Concrete including cantilever forms for pools, a variety of countertop forms, step liner forms and several wall cap forms. Discuss your project with our expert staff. It’s important to choose the right form for each project and we’re here to help.
