Concrete Joint Sealant in Northern Colorado
Protect Your Concrete From Water Damage and Future Settlement
Are the joints in your driveway, sidewalk, or patio starting to crack or open up?
Those gaps between concrete slabs are not just cosmetic. They are expansion joints designed to allow movement. But when they fail, water can seep underneath the slab and wash away the supporting soil.
Over time, that leads to voids, settlement, and uneven concrete.
Liftwerx Concrete Lifting Services provides professional concrete joint sealant to help protect your slabs from water intrusion and long-term damage.
Why Joint Sealant Matters
Concrete expands and contracts with temperature changes. That is why control joints and expansion joints are installed between slabs.
When joint sealant cracks or deteriorates, water can enter below the surface. In Northern Colorado, freeze-thaw cycles make this worse. Water freezes, expands, and pushes against the soil and slab.
This can cause:
- Soil erosion beneath the slab
- Voids forming under concrete
- Cracks spreading over time
- Uneven slabs
- Premature concrete failure
Sealing joints helps reduce water intrusion and protect the base underneath your concrete.
Where Joint Sealant Is Used
We apply high-quality joint sealant for:
- Driveways
- Sidewalks and walkways
- Patios and porches
- Garage floors
- Pool decks
- Commercial concrete surfaces
If you have already invested in driveway leveling or other concrete lifting services, joint sealing helps protect that investment long-term.

Signs Your Joints Need Sealing
You may need joint sealant if you notice:
- Cracked or missing sealant
- Gaps between slabs
- Weeds growing in joints
- Water pooling along seams
- Sand or soil washing out from joints
Addressing joint issues early helps prevent larger repair costs later.
Our Joint Sealant Process
We follow a clean, controlled process to ensure proper adhesion and long-term performance.
1. Clean the Joint
We remove old sealant, debris, and loose material to create a clean surface.
2. Prepare the Joint
If needed, we install backer rod to control depth and ensure proper sealant performance.
3. Apply High-Quality Sealant
We apply flexible joint sealant designed to expand and contract with your concrete.
The result is a clean finish that helps protect your slab from water intrusion.
