POLYUREA JOINT FILLING

Polyurethane Joint filling is recommended for concrete floors to protect the saw cut edges of control joints, isolation joints, and cold pour joints. Cart, forklift, and vehicle traffic all contribute to wear on commercial and industrial floors. Saw cuts established in the slab at the initial time of placement allow the slab to move during initial hydration allowing the slab to crack in specific areas. These saw cuts are referred to as Control Joints, Isolation Joints, and Cold Pour Joints. If left untreated these saw cuts fill with debris from the floor and traffic.

Concrete slabs are designed to move under load. As a loaded forklift rolls across a joint, the slab will depress slightly exposing the leading edge of the adjacent slab. Tires will hit this edge causing chipping. This action over time will cause large cracks and damage to the joints making the floor surface uneven and potentially causing safety concerns. These fillers are typically two-component fast curing Polyureas. The main purpose of these fillers is to keep debris from collecting in the joints and to protect the edges from degradation. To remediate this the industry developed what is now referred to as semi- ridged joint fillers. Semi-ridged joint fillers keep debris from collecting in the joints and protect the edges from degradation.

The process for filling the joints consists of to mechanically abrading the side of the joint so the Polyurea can bond properly to the edges. The joints are then vacuumed to remove any debris left from the cleaning. Next, a release agent is rolled over the floors at the joints to keep the caulking material from adhering to the horizontal surface of the concrete. Release agents are also called stain preventing films.

The floor joints are overfilled so that once complete the joint filler is flush with both sides of the joint.  A long-poled razor scraper is run along the floor to remove the excess material leaving the joint flush and even. This is different than most caulking procedures as normally concave tooling would be done to increase the flexibility of the material. Polyurea joint fillers cure quickly, some as fast as one minute and others can take 45 minutes to a couple of hours before they are ready for the next step in installation which is shaving. There are several different ways to shave these joints, but it is often done with a long-poled razor scrapper. The scrapper is run along the floor and removes the excess material leaving the joint filled flush and even. There are a great many types of polyurea’s on the market with each one having specific properties based on building design, environment, and area usage. Usually, a two-component joint pump machine is used for this application.

Filling the joints in your facilities floors can save thousands of dollars down the road when it comes time to remediate these joints due to safety concerns. Concrete Solutions utilizes Polyurea materials from Sika, Metzger McGuire, SASE Company, Euclid, BASF/Master builders, and Seal Boss.

Frequently Asked Questions

I have an existing facility that has not had the Control Joints treated, can they still be filled?

Yes, The joints can be evaluated repaired, and filled. Once complete the joints will now be protected from wear.

Is the process expensive?

Not compared to the cost of remediation. Typically new floors can have there control joints filled for between $3.25-$5.25 LFT depending of the facilities specific requirements.

How long does the process take?

The process is quick. Once completed and shaved the floor area can be put back into immediately. There is no additional cure time required.

Can this be done while our facility is in operation?

Yes, The materials are low or no odor and some are CFIA (Canadian Food Inspection Agency) certified for processing facilities. All preparation equipment is attached to vacuums with filtration systems.

Polyurea Joint Filler is a technically advanced self-leveling fast-setting caulk. It is semi-rigid, allowing small slab movement but strong enough to protect the edges (shoulders) of concrete joints from spalling under extreme loading.

The fillers have been specifically designed for industrial floor applications and are typically tack-free in 5 to 15 minutes allowing for vehicle or foot traffic within 1 hour.
