Cracked Concrete Joints Letting Water In?
Open joints and cracks in concrete might not seem like a big issue at first, but they can quickly lead to bigger problems. When water gets into these gaps, it can wash out the soil underneath, cause further cracking, and speed up deterioration over time.
If you’re noticing separated joints, widening cracks, or areas where sealant has worn away, it’s a sign your concrete is no longer protected.
At Level Up Concrete Raising, we provide professional concrete caulking across the Denver Metro area to seal joints, protect your surfaces, and help prevent further damage.
What Causes Concrete Joints and Cracks to Open?
Concrete naturally expands and contracts over time, but several factors can cause joints and cracks to worsen:
- Exposure to moisture and water intrusion
- Freeze-thaw cycles common in Colorado
- Aging or deteriorated sealant
- Soil movement beneath the concrete
- Heavy use and daily wear
When joints are left unsealed, water can enter below the surface and begin to weaken the support underneath.
Common Concrete Joint Problems We Fix
If you’re seeing any of these issues, your concrete may need caulking:
- Open or separated expansion joints
- Cracks forming between concrete slabs
- Old or missing joint sealant
- Water getting into joints or cracks
- Edges of concrete starting to break down
- Visible gaps that continue to widen over time
These problems often lead to more serious damage if not addressed early.
Cracks and open joints are often connected to other concrete issues. When water gets below the surface, it can create voids and lead to sinking or uneven slabs. Our team also provides void filling, driveway leveling, and concrete slab leveling. Taking care of both the surface and what’s happening underneath helps protect your concrete long-term.

Concrete Caulking FAQs
Concrete caulking plays a key role in protecting your surfaces from water damage. When joints and cracks are properly sealed, it prevents water from getting underneath the slab where it can cause erosion and shifting. Over time, unsealed joints can lead to larger structural issues, so keeping them sealed helps maintain the stability and lifespan of your concrete.
If you can see open joints, missing sealant, or cracks that are starting to widen, it’s a good indication that your concrete needs attention. You may also notice water collecting in these areas after rain. These are signs that the protective seal has failed and should be replaced to prevent further damage.
Leaving joints unsealed allows water to enter beneath the concrete, which can lead to soil erosion and voids forming underneath. As the support weakens, the slab can begin to sink or shift, creating uneven surfaces. Over time, this can turn a simple sealing issue into a much larger repair.
Most caulking projects can be completed fairly quickly, depending on the size and number of joints that need to be sealed. The process is straightforward and typically causes minimal disruption, making it a convenient way to protect your concrete.
The sealant is applied cleanly and designed to blend in with the existing concrete as much as possible. While you may still see where joints are sealed, the finished result looks clean and professional, especially compared to open or deteriorating cracks.
Caulking helps manage how concrete expands and contracts, which can reduce stress on the slab. While it won’t stop all cracking, it plays an important role in preventing cracks from worsening and helps protect the structure over time.
Yes, sealing joints helps keep water from getting underneath the slab, which is one of the main causes of soil erosion and void formation. In many cases, proper sealing works alongside services like void filling to help maintain a stable base.
No, both newer and older concrete can benefit from proper joint sealing. Even newly installed concrete needs sealed joints to handle expansion and protect against moisture over time.
