Joint Filling

Joint Filling

Joint filling is an important step in the process of refinishing your concrete floors, especially in commercial or industrial areas where there is a high traffic volume or equipment such as forklifts are used. Properly filled and finished expansion joints will help protect your floors from serious, costly damage. When not filled, the edges of the joints are more easily chipped or cracked and are more of a safety hazard that can cause trips and falls.

Control Joints and Expansion Joints

The two types of joints used in concrete flooring are control joints and expansion joints, both of which play a big part in keeping your floors safe and damage-free. These joints are designed to help with the natural expanding and contracting of concrete due to settling, changing weather conditions, and heavy use. Even seamless floors will contract, pulling away and creating gaps between the floor and walls. These gaps require attention and are easily filled.

Using Epoxy and Polyurea Fillers

Most joint filling is done using an epoxy or polyurea filler that creates a sealed, uniform surface for your floor, protecting the concrete from water seepage and chipping. These fillers can be tinted or dyed to match the floor color, or a contrasting color may be used to add more interest.
