Common Causes Of Shifting Coping

There are several reasons why pool coping may shift, including environmental and construction-related causes. Pinpointing the reason helps determine how to fix the issue and prevent it from recurring.

Common causes include:

- Soil movement and settling: In Los Angeles, soil expands and contracts because of dry weather followed by sudden rain. This movement strains the pool shell and its surroundings, which can knock coping stones out of place.

- Poor installation: If the sub-base beneath the coping wasn’t packed correctly or if mortar was spread unevenly, the coping won’t stay in place. Over time, this can lead to visible misalignment and increased water exposure.

- Earthquakes and natural shifts: Southern California experiences seismic activity that may not seem severe but can nudge the earth enough to impact pool structure and coping alignment.

- Drainage issues and water buildup: Water that collects behind the coping creates pressure. Over time, that pressure shifts stones and causes cracking. While freeze-thaw cycles aren’t major concerns in Southern California, sustained moisture around the pool’s edge is still a threat.

- Adjacent deck movement: Sometimes, the pool coping is fine, but the surrounding deck moves. If the concrete slab around the pool has shifted due to settling ground or poor pour work, it may tug at the coping and cause misalignment.

Knowing what’s causing the coping to shift lays the groundwork for addressing the issue correctly, rather than relying on surface-level fixes that won’t hold up.

Steps To Take When You Notice Shifting Coping

The moment you spot shifting coping, act quickly to keep your pool safe and functional. Loose or cracked edges can be a hazard for everyone, especially kids and those walking around barefoot.

Here’s what to do right away:

- Block off the area: Keep swimmers and guests away from the part of the pool showing signs of shifting.

- Get an expert opinion: Call a professional to assess the condition of the coping, deck, and any underlying structural areas.

- Use temporary safety patches: Cover sharp or open gaps with tape or cushioning material if needed. Avoid walking on unstable sections to reduce further damage.

- Monitor changes closely: Keep an eye on the issue while waiting on a professional visit. Watch for increases in cracking, lifting, or water pooling.

Trying to fix pool coping without knowing the cause can make things worse. That’s why bringing in someone who understands pool structure and construction is worth the time. A repair expert can tell if deeper fixes are needed and create a long-term plan to keep the problem from returning.

Preventative Measures To Avoid Future Issues

Preventing shifting coping is about smart planning and upkeep. Once your pool is built, you want it to last for years with as few surprises as possible. Good construction practices and regular maintenance are your best defense.

Here are some ways to reduce the risk of future coping problems:

- Work with experienced installers who understand local soil behavior

- Ensure proper grading and drainage systems are in place around the pool

- Schedule seasonal inspections, especially after heavy rain or tremors in the area

- Trim back shrubs and trees with aggressive roots that can affect nearby structures

- Watch for signs of movement and catch them early before they grow

Water needs to move away from your pool, not toward it. Make sure your yard or deck design allows for proper drainage. Water that collects near the coping line will eventually affect the bond between the coping and the pool structure.

Keep an eye on the condition of your coping across all seasons. Cracks, settling, or tiny shifts are all part of early warnings that should be addressed sooner rather than later. This can prevent a small fix from turning into a major renovation.
