CONCRETE RAISING WITH GROUT

Grout is very simply a term to describe various mixtures of sand with a little (and sometimes zero) cement . Grouts can vary widely from various applications and can contain a wide variety of admixtures for each individual purpose. So by just saying "grout" many different types of materials could be referenced with this one word.

For Concrete Raising purposes, the grout used can be customzied for each project and is often specified by the owner of the project. Typicially, the purpose of the Concrete Raising is only to replace the sub-base under the concrete that has eroded. The grout used to replace this can be a simple mixture of sand, a little cement, and an admixture of clay, fly-ash or bentonite to make the material pump easily. This mixture is inexpensive and does more than an adequate job replacing the missing sub-base soil with a sturdy material that is not prone to erode or shirk.
