Common Causes Of Uneven Pools
Uneven pools can cause many problems. Water may not drain properly. Swimming becomes unsafe and uncomfortable. Understanding common causes helps fix the issue fast.
Soil Settlement Issues
Soil under the pool can settle unevenly. Soft or loose soil shifts over time. This causes one side to sink. Heavy rain or drought can worsen soil movement. Proper soil compaction before building is important.
Improper Installation
Pools built without correct leveling will be uneven. Builders might skip important steps. Incorrect measurements can cause slopes. Poor foundation work leads to future problems. Always check the installer’s experience and work quality.
Water Pressure Effects
Water pressure from inside and outside can move the pool. Groundwater pushing up can lift one side. Pool water pressure may cause walls to lean. Pressure changes need proper drainage systems. Balancing water forces protects pool structure.
Signs Your Pool Is Uneven
Knowing the signs of an uneven pool helps protect your investment. Uneven pools cause safety risks and damage over time. Early detection can save costly repairs and keep your pool safe.
Some signs are easy to spot. Others need careful observation. Watch your pool closely for these common clues.
Visible Water Level Differences
Water naturally seeks a level surface. Uneven pools show water higher on one side. This difference is clear along the pool’s edge. It looks like the water is slanting or tilted. Check the water line against the pool walls regularly. Large gaps or slants signal uneven ground or structure.
Structural Cracks And Damage
Uneven pools often develop cracks in the walls or floor. These cracks grow as the pool shifts or sinks. Look for small cracks near corners and steps. Cracks may leak water or cause tiles to loosen. Damage on one side more than another suggests uneven settling.
Unusual Water Circulation
Water moves differently in an uneven pool. Pumps may struggle to circulate water properly. You might see water pooling in low spots. Skimmers may not catch debris evenly. Poor circulation can cause cloudy water or algae buildup. Notice changes in pump pressure or flow speed.
Quick Diy Fixes
When your pool is higher on one side, quick fixes can help. These simple steps can balance your pool without hiring professionals. Most fixes use materials you already have at home. Acting fast prevents more damage and keeps your pool safe.
Adjusting Pool Water Levels
Check your pool water levels first. Lower the water on the higher side slowly. Use a siphon or a bucket for this. Watch the water level carefully to avoid empty spots. Adding water to the lower side can help too. This step balances water pressure on both sides.
Using Pool Fillers
Fill gaps under the higher side with pool fillers. Use sand, gravel, or foam blocks. Pack the filler tightly to support the pool structure. This method helps level the pool base. It also stops the pool from sinking further on one side.
Temporary Support Solutions
Place wooden blocks or bricks under the higher side. Make sure they fit snugly and do not move. These supports hold the pool steady temporarily. Use this fix while planning a permanent solution. Check supports regularly to keep the pool safe.

Professional Solutions
When a pool is higher on one side, professional solutions can fix the problem safely. Experts use tested methods to balance the pool. These solutions protect your pool and keep it stable for years.
Pool Re-leveling Techniques
Pool re-leveling involves adjusting the pool’s base to make it even. Professionals lift the pool and add or remove soil under it. This process restores the pool’s balance without damaging the structure. It prevents water from pooling unevenly or spilling over one side.
Soil Stabilization Methods
Soil stabilization strengthens the ground beneath the pool. Specialists use materials like grout or chemicals to firm loose soil. This stops soil from shifting or sinking under the pool. Stable soil means the pool stays level and safe over time.
Drainage System Improvements
Proper drainage keeps water away from the pool’s foundation. Experts install or fix drainage systems to direct water flow. This prevents soil erosion and uneven settling around the pool. Better drainage reduces the risk of future leveling problems.
Preventing Future Unevenness
Preventing future unevenness in your pool is key to keeping it safe and attractive. Uneven pools can cause damage and make swimming uncomfortable. Taking steps early helps avoid costly repairs and frustration.
Proper Site Preparation
Start with a solid base for your pool. Clear the area of rocks, roots, and debris. Level the ground using a professional tool. Compact the soil to prevent sinking. A flat, firm foundation stops one side from rising higher.
Regular Pool Maintenance
Check your pool often for signs of movement or cracks. Clean the pool and its surroundings regularly. Fix small problems before they grow. Keep your pool balanced by adjusting water levels. This helps maintain even pressure on all sides.
Monitoring Water Pressure
Water pressure can affect your pool’s stability. Watch for unusual changes in water level. Ensure pumps and filters work properly to keep water flow steady. Uneven pressure may cause one side to shift higher. Keep water pressure balanced for pool safety.

Tools And Materials Needed
Fixing a pool that is higher on one side needs the right tools and materials. These help check the level and repair the pool safely. Using proper tools makes the work easier and more accurate.
Leveling Instruments
Start with a spirit level or a laser level. These tools measure how much one side is higher. A long straight edge or a carpenter’s level also works well. They show uneven areas clearly. A tape measure helps to check distances and depth.
Pool Repair Supplies
Use pool patch kits for small cracks or leaks. Sealants and waterproof adhesives help fix leaks. Concrete mix may be needed to adjust the pool base. Sand or gravel helps level the ground under the pool. Have a trowel or putty knife ready for smooth spreading.
Safety Equipment
Wear gloves to protect your hands from chemicals and rough surfaces. Safety goggles keep dirt and splashes out of your eyes. Use a mask if working with dust or strong fumes. Non-slip shoes prevent accidents around wet areas. Keep a first aid kit nearby for minor injuries.
