As Louisianians, we know that phrase all too well, “rainy season is coming.” While most of us worry about our gardens flooding or that pesky leak in the garage, there’s another part of your property silently dreading the downpour: your concrete surfaces. Those driveways, sidewalks, and patios that faithfully support your outdoor activities are about to face their annual water torture test. But don’t worry, with a little preventative care, your concrete can weather the storm just fine. Here’s what you need to know about concrete expansion joint filler before the clouds roll in.
Concrete Slabs Need Expansion Joints Filler To Stay Healthy
You might have noticed those straight lines cutting across your driveway or sidewalk. No, those aren’t cracks, they’re actually expansion joints, and they’re there by design. Think of them as your concrete’s pressure release valves.
Concrete, despite its rock-solid appearance, is constantly moving / expanding in heat and contracting in cold. Without those joints, your concrete would crack like the top of a brownie that rose too quickly in the oven. But here’s where many Shreveport and Bossier City homeowners go wrong: leaving those joints unfilled.
Empty expansion joints are like leaving your windows open during a storm. Water seeps in, soil washes out, and before you know it, what started as a small issue becomes a concrete catastrophe. Joint filler creates a waterproof seal that allows for movement while keeping the damaging elements out. It’s like giving your concrete a good raincoat before the storms hit.
Heavy Rains Will Further Damage Your Concrete
Louisiana’s famous downpours don’t just put a damper on your weekend barbecue plans – they’re actively plotting against your concrete surfaces. Our state averages over 60 inches of rainfall annually, with spring bringing some of our heaviest precipitation. That’s a lot of water looking for somewhere to go.
When water finds its way into unfilled concrete joints, it creates a damaging cycle that accelerates with each rainfall:
- Water pools in the joints and seeps beneath the slab
- Soil underneath becomes saturated and shifts
- Freeze-thaw cycles in cooler months expand and contract the moisture
- Concrete begins to crack, sink, or heave
- More water enters through new gaps, making the problem worse
It’s like watching a slow-motion disaster movie, except the star is your driveway and the villain is simply H2O. The good news? This sequel can be canceled with proper joint maintenance before the rainy season arrives.
Voids Under Your Slabs Will Continue to Grow Without Concrete Filler
“Out of sight, out of mind” might work for last week’s leftovers in the fridge, but it’s a dangerous approach to concrete maintenance. Those invisible spaces beneath your concrete slabs, voids, are silently growing larger with every rainfall.
Here’s what’s happening beneath your feet: When water washes away the soil through unfilled joints, it creates small spaces. These voids might start small, but like that gossip at a family reunion, they spread quickly. Soon, your concrete has no support underneath, and that’s when the cracking and sinking begin.
By the time you notice a problem on the surface, the issue underneath has often grown substantially. It’s like ignoring a small leak in your roof until your ceiling caves in. It’s preventable with early intervention, but costly to fix once it’s advanced.
Proper joint filling creates a barrier that prevents water from eroding the foundation of your concrete slabs. Combined with concrete lifting and leveling for existing voids, you’re essentially giving your concrete a solid foundation to stand on when the rains come.
Get Expansion Joint Filler For Your Driveways and Sidewalks
Not all concrete surfaces are created equal, and your high-traffic areas deserve special attention. Driveways and sidewalks take the brunt of both natural elements and daily use, making them particularly vulnerable to water damage.
Your driveway, which regularly supports vehicles weighing thousands of pounds, can quickly develop serious issues if joints aren’t properly maintained. What starts as a small dip can become a tire-swallowing pothole after a few heavy rains. Similarly, those sidewalks that guide visitors safely to your door can become trip hazards when water undermines their foundation.
Professional-grade expansion joint filler provides several benefits:
- Creates a watertight seal that prevents moisture penetration
- Remains flexible through seasonal temperature changes
- Prevents debris from collecting in joints (which can prevent proper expansion)
- Extends the life of your concrete investments
- Improves the overall appearance of your property
The best part? Joint filling is one of the most cost-effective maintenance tasks you can perform on your concrete. For pennies on the dollar compared to replacement costs, you’re buying up to twenty years of additional service life for your concrete surfaces.
Uneven Concrete Slabs Will Sink And Settle Without Proper Maintenance
We’ve all seen it. That driveway that looks like a miniature mountain range, or the sidewalk that resembles a frozen wave. Uneven concrete isn’t just an eyesore; it’s a safety hazard and a sign that water has already done significant damage beneath the surface.
When concrete slabs sink unevenly, they create new low spots where water can pool. This standing water accelerates the deterioration process and can even compromise your home’s foundation if the slabs are adjacent to your house. It’s a problem that compounds itself – more water leads to more sinking, which creates space for more water.
Louisiana’s unique soil composition, particularly our clay-heavy soil around Shreveport and Bossier City, makes our region especially prone to settlement issues. Our soil expands when wet and contracts when dry, creating a constant motion beneath your concrete. Without proper joint maintenance, this natural soil movement can wreak havoc on your concrete surfaces.
Get Your Concrete Leveled Before Concrete Joint Repair to Guarantee Healthy Concrete Surfaces
If you’re noticing unevenness in your concrete, there’s a proper order of operations to restore its health. Think of it like healthcare, you need to address the underlying condition before applying the preventative medicine.
Concrete leveling (sometimes called foam jacking or slabjacking) should come first. This process fills those voids we mentioned earlier and raises sunken concrete back to its proper position. Using specialized equipment, our technicians can inject a stabilizing material beneath the concrete, providing it with the solid foundation it needs.
Only after your concrete is level and properly supported should joint filling be applied. This order ensures that:
- The joints are at their proper width and alignment
- The expansion joint filler can be applied evenly
- The entire system works together to protect against future damage
Attempting to fill joints on unlevel concrete is like putting a new roof on a house with a crumbling foundation. It addresses one problem while ignoring the more serious underlying issue.
