How To Use Rockite Expanding Hydraulic Cement

Rockite Expanding Hydraulic Cement

When purchasing a cement product for your chain link fence, hydraulic cement is a safe option to help you patch concrete and brick, anchor bolts, screws, balustrades, gates, fencing, railings, and more. Hydraulic cement is a type of product that mixes with water and sets quickly. It can be used to reinforce concrete and masonry structures.


Rockite, a hydraulic cement made in Cleveland, Ohio, sets within 15 minutes and, after an hour, is comparably stronger than concrete. It’s a great addition to fencing projects where you must set a fence fast.
