Are Open Concrete Joints Letting Water Get Under Your Slabs?
Concrete joints are supposed to help control movement. But when those joints are open, cracked, or missing caulk, water can get underneath the concrete.
Over time, that water can wash away soil, create voids, and lead to sinking concrete, cracks, uneven slabs, and trip hazards.
The Concrete Team provides concrete joint sealing and caulking services for driveways, sidewalks, patios, pool decks, garage floors, commercial concrete, and more throughout Upstate New York.
Why Concrete Joints Open Up
Concrete expands, contracts, shifts, and moves with weather changes. In Upstate New York, freeze-thaw cycles, rain, snow, salt, and daily use can all affect concrete joints.
Common reasons concrete joints open up include:
- Old or missing joint caulk
- Freeze-thaw movement
- Water getting between slabs
- Soil washing out below the concrete
- Heavy vehicle traffic
- Sun exposure and weather damage
- Poor drainage near the concrete
- Normal concrete movement over time
When joints are left open, water has an easy path under the slab. That can lead to bigger problems if it is not corrected.
If your concrete has already started sinking, joint sealing may need to be paired with concrete slab leveling or driveway leveling. If the concrete has visible cracks, our concrete crack repair service may also be a good fit.
Signs You May Need Joint Sealing or Caulking
Open joints may not seem like a big problem at first. But they can allow water, dirt, weeds, and debris to get between and below the slabs.
You may need concrete joint sealing if you notice:
- Gaps between concrete slabs
- Old caulk pulling away from the joint
- Weeds growing between slabs
- Water draining into open joints
- Dirt or soil washing out near the concrete
- Ants or insects entering through joints
- Cracks forming near slab edges
- Uneven concrete near open joints
- Pooling water around your driveway, patio, or walkway
- Loose or missing filler between concrete sections
Joint sealing is often a smart preventative repair. It helps protect the concrete before water causes more damage below the surface.

Why Homeowners & Businesses Choose Us
Our Joint Sealing & Caulking Process
Our process is simple and focused on protecting your concrete from water damage.
Step 1: Clean and Prepare the Joint
We clean out the joint and remove loose debris, old failed caulk, dirt, weeds, and weak material. The joint needs to be properly prepared so the new material can bond.
Step 2: Install Backer Material When Needed
For larger joints, we may install backer rod or filler material before caulking. This helps control the depth of the sealant and gives the joint better support.
Step 3: Apply Concrete Joint Sealant
We apply a flexible concrete sealant designed to handle movement. Once installed, the joint is sealed to help keep water, dirt, and debris from getting below the concrete.
Benefits of Concrete Joint Sealing
Joint sealing is a simple way to help protect your concrete and reduce future repair needs. It is especially helpful for concrete exposed to rain, snow, ice, salt, and heavy use.
Benefits include:
- Helps keep water from getting under concrete slabs
- Helps reduce soil washout below the concrete
- May help prevent future sinking and settling
- Helps protect driveways, sidewalks, patios, pool decks, and slabs
- Helps reduce weed growth between joints
- Helps improve the look of old open joints
- Helps reduce trip hazards caused by future slab movement
- Costs less than waiting for larger concrete problems to develop
- Can often be completed with less disruption than larger repairs
- Helps support longer-lasting concrete repairs after lifting or crack repair
In many cases, joint sealing is recommended after concrete lifting or leveling to help protect the repair and reduce water problems going forward.
