Concrete Caulking and Joint Sealants
Concrete caulks and sealants are important materials in our concrete repair services, offering effective solutions for addressing cracks, gaps, and joints. They’re typically made of flexible polymers and are applied to the damaged or vulnerable areas of concrete structures to create a waterproof and durable seal. Concrete caulks are commonly used for filling small cracks and gaps, while specialized sealants are ideal for larger joints. The application of these products helps prevent water intrusion, which can lead to further damage through Colorado’s winter freeze-thaw cycles as well as chemical corrosion. By sealing the concrete, caulks and sealants ultimately help prevent the development of more extensive issues. We commonly use them on parking garages, stadiums, office buildings, and much more.

Sealant is a maintenance item, not a permanent fix
Joint sealant has a service life. We look at sealants on a three to five year cycle, the joints that move the most fail first, and none of that is a defect. Sealant is designed to be replaced. What is worth knowing is the cost of leaving it. A failed joint is an open path for water and chloride into the structure, and the damage does not stay at the joint: water tracks along it, gets into the slab, and reaches reinforcing steel or post-tension anchors. That is how a sealant job turns into a concrete repair job. Replacing sealant on a cycle, before it fails rather than after, is some of the cheapest maintenance available on a concrete structure. We can walk your joints, tell you what is left in them, and put a realistic interval on it.
Where sealants go
Construction joints, control joints, perimeter details, penetrations, the transition between two materials, and anywhere else the structure is designed to move or two surfaces meet. Urethane and silicone behave differently, and the right one depends on the joint, the movement, the exposure and what the surface is.
Questions we get asked
How often does joint sealant actually need replacing?
We always say three to five years and we will come and take a look at your sealants. Whether they need replacing at that point depends on a lot of things: conditions, the structure itself, how much it moves, and UV. Sealants are an oil change. We tell people that all the time. If you are not paying attention to your sealants, you are going to blow the engine.
Why does sealant not last longer in Colorado?
UV, mostly. Colorado is hot and as far as UV goes we are getting beaten on, and UV degrades sealant. Put that together with the movement in the structure and the ordinary wear a joint takes, and sealant here works hard for every year it gives you.
