Cementitious Expansion Grout
On any construction project, grout can be found everywhere. Mounting Handrails, Setting Anchor Bolts, Under Base Plates, etc. The important thing to consider when using grout is exposure to the elements.
Typical construction uses a “controlled expansion” grout, i.e. – as it sets it expands slowly to create pressure. This can be achieved with a Portland Cement based grout, or gypsum based. The difference is the Portland cement type will expand and remain at its expanded pressure indefinitely in both interior and exterior environments.
