At Cor-Form, we offer a unique product that allows you to infill a core hole in a concrete floor quickly, safely, and economically. Traditionally, you would need access to the floor below in order to fill a core hole. With Cor-Form, any core hole can be filled with ease from the floor you are working. For more information, check us out at www.cor-form.com. You will find installation instructions, a specification, purchasing page, retailers, and much more. We look forward to helping you fill core holes in the future!
