In El Cajon, CA—where sunny skies and warm temperatures are the norm—concrete is a key part of both residential and commercial landscapes. From driveways and patios in Fletcher Hills to walkways in downtown El Cajon, concrete provides a reliable, long-lasting foundation. However, the region’s dry climate, occasional heavy rains, and shifting soils can take a toll on concrete over time.
At Legendary Concrete – El Cajon, we understand the unique stressors concrete faces in this area. If your concrete surfaces are beginning to look worn, unsafe, or uneven, it may be time to repair—or replace—them. Below are the top five signs your concrete needs professional attention.
1. Expanding or Deepening Cracks
Concrete naturally develops small cracks over time, especially in areas with temperature swings or shifting foundations. But if the cracks in your driveway, patio, or walkway are getting longer, wider, or forming patterns like spiderwebs or stair-steps, it’s more than a cosmetic issue.
In El Cajon, soil movement due to drought and sudden rain can cause significant stress beneath concrete surfaces. These cracks may also allow water intrusion, leading to erosion and structural weakening. While some small cracks can be filled or patched, worsening cracks usually indicate the need for slab replacement.
2. Sinking or Uneven Slabs
One of the most obvious signs your concrete needs help is when it begins to sink or settle unevenly. You might see this as a dip in your sidewalk or a sloped area in your driveway. These issues are especially common in older areas of El Cajon where soil was not properly compacted during initial construction.
Sunken concrete not only poses a tripping hazard, but it can also create problems with drainage, leading to water pooling near your foundation. In many cases, replacement is a more reliable solution than temporary leveling, especially if the base beneath the slab has eroded.
3. Flaking or Spalling Surface
When the surface of your concrete begins to chip, flake, or peel away, this is known as spalling. It often starts small but spreads quickly—particularly in areas that experience high foot traffic or exposure to moisture. El Cajon’s occasional rainfall combined with constant sun exposure can speed up this process.
Spalling affects both appearance and strength. While resurfacing may work for minor cases, widespread or deep erosion typically means the concrete needs to be replaced to prevent further decay and ensure long-term durability.
4. Water Pooling or Drainage Problems
If you notice standing water on your driveway, patio, or walkway after watering your yard or after a rare El Cajon rain, that’s a sign of improper grading or slab movement. Water should always flow away from your home—not sit on top of your concrete.
Improper drainage can lead to increased surface wear, cracking, mold, or even damage to your home’s foundation. When drainage is compromised due to poorly pitched or sunken concrete, the best solution is often to replace the slab with one that has the correct slope and reinforcement.
5. Rust Stains or Exposed Steel
If you see rust-colored stains or spots where steel reinforcement is showing through your concrete, this is a serious red flag. Concrete reinforced with rebar or mesh is strong—but only when the internal steel remains dry. Moisture intrusion can lead to rust, which causes the steel to expand and crack the surrounding concrete.
Once the rebar is exposed, patching the surface won’t solve the problem. A full replacement is usually necessary to prevent continued corrosion and to restore the structural integrity of your concrete surface.
