Whether you’re experiencing harsh winter conditions or scorching summer weather, we’ve got you covered. Our effective and reliable concrete joint filler products preserve and protect pavement, while keeping out water.

What Are Concrete Joints?

Concrete joints are the intentional, pre-planned spaces left between slabs of concrete. These joints can be seen in many concrete applications, but a common example is found in sidewalks. The purpose of these intentional gaps is to allow the concrete to expand or contract during fluctuations in temperature throughout the year, preventing costly and unsightly damage.

How Is Concrete Joint Filling Repair Conducted?

When you are looking to repair your concrete joints, you’ll first need to acquire a reliable concrete joint filling material, with enough to handle the job you have in mind. From there, you will need to take the following steps:

  1. To prepare your joints and cracks for filling, free them of any weeds, grass, debris, or water. For various steps in this process, weed eaters, power washers, air compressors, brooms, and leaf blowers can all be worthwhile to have on hand, but not all will be needed in every case.
  2. You will then want to check the soundness of the pavement in the area to be repaired. Make sure you don’t see damage caused by freezing or undermining. If you see undermined areas (an example is shown in our video below), know that the damage could be severe and may require backfilling before any application of your concrete joint filler.
  3. Should your joint require backfilling as mentioned in the previous step, you will want to partially fill the gap with clean sand or backer rods. If the undermining is not filled completely with your first application of concrete joint filler, or the liquid lowers in the crack as it runs down into the undermined areas and settles, additional joint filler will be required to fill the space evenly with the surface.
  4. When applying your concrete joint filler, you can either pour directly from the container, use a pour pot, or use a pump and wand system.
  5. During application, simply fill the joint with the material ¾ of the way down the joint, allowing the liquid to fill the space from the bottom to the top. Wait a few minutes to let the material seep completely into the gap.
  6. Using a U- or V-shaped squeegee, or a similar tool, push and spread the remaining filler material the full length of the joint, including the in remaining quarter section of the joint that previously lacked material.
  7. You will want to make sure to level the concrete joint filling material with the existing pavement. Also, allow 1-2 hours of curing time between coats as needed.
  8. Be sure to clean your application tools before the material dries on them.

It should be noted that our concrete joint filling material should not be applied when the ambient temperature is expected to drop below 50 degrees Fahrenheit, or when rain is expected within 24 hours following its application.

Also, if your concrete filler has been stored for more than thirty days, some separation or settling of the liquid may have occurred. In this case, simply stir, mix, or shake the container prior to application to achieve a consistent mixture.
