Quick Answer
Pebble loss occurs when stones fall out of aggregate pool surfaces due to poor installation, aggressive water chemistry, structural movement, or normal wear. Individual pebbles cannot be reattached effectively. Small areas can be patched temporarily, but widespread loss requires complete resurfacing. Most pebble surfaces last 15-20 years when properly installed and maintained.

Understanding Pebble Pool Surface Loss
How Pebble Surfaces Work
Pebble pool surfaces (like Pebble Tec, Pebble Sheen, or similar aggregate finishes) consist of small stones held together by a cement-based matrix. The pebbles provide color and texture while the cement provides structural integrity and adhesion to the pool shell.
Pebble Surface Components:
Pebbles/Aggregate:
- • Natural river stones or manufactured aggregate
- • Various sizes from fine to large (typically 1-6mm)
- • Multiple colors for aesthetic appeal
- • Smooth, water-polished surfaces
Cement Matrix:
- • White or colored portland cement base
- • Polymer additives for flexibility
- • Bonding agents for shell adhesion
- • Chemical additives for durability
Signs of Pebble Loss:
- •Individual pebbles found during cleaning
- •Rough or pitted surface areas
- •Visible cement matrix beneath pebbles
- •Color changes where pebbles are missing
- •Loose pebbles that move when brushed
Common Loss Locations:
- ⚠️High traffic areas (steps, benches)
- ⚠️Around pool fittings and returns
- ⚠️Waterline and splash zones
- ⚠️Areas with structural cracks
- ⚠️Corners and inside radius curves
Common Causes of Pebble Loss
1. Poor Initial Installation
Installation Problems:
- • Improper cement-to-pebble ratio
- • Inadequate surface preparation
- • Wrong environmental conditions during application
- • Poor mixing or application techniques
- • Insufficient curing time before filling
Quality Indicators:
- • Experienced, certified installers
- • Proper surface preparation and bonding
- • Ideal temperature and humidity conditions
- • Manufacturer-approved materials and ratios
- • Professional 30-day startup process
2. Aggressive Water Chemistry
Chemical Attack:
- • Low pH dissolves cement matrix
- • Low calcium hardness creates aggressive water
- • Over-chlorination weakens cement bonds
- • Improper acid washing techniques
- • Poor chemistry during initial startup
Dallas-Fort Worth Factors:
- • Naturally soft fill water
- • Acid rain from urban pollution
- • Heavy rain dilution events
- • High temperatures accelerating reactions
- • Pool service provider knowledge gaps
3. Mechanical Damage
Physical Stress:
- • Aggressive brushing with wire brushes
- • High-pressure washing damage
- • Heavy foot traffic on steps and benches
- • Impact from pool equipment or toys
- • Structural movement and settling
Prevention Methods:
- • Use only soft nylon brushes
- • Gentle cleaning techniques
- • Regular maintenance to prevent buildup
- • Address structural issues promptly
- • Educate pool users on surface care
4. Environmental Factors
Natural Wear:
- • Freeze-thaw expansion and contraction
- • UV radiation degrading cement matrix
- • Thermal stress from temperature changes
- • Ground movement and settling
- • Normal aging after 15-20 years
Accelerating Conditions:
- • Extreme temperature swings
- • High UV exposure areas
- • Poor drainage around pool
- • Excessive chemical use
- • Lack of regular maintenance
Step-by-Step Diagnosis
Assess Extent of Pebble Loss
Examine entire pool surface for areas where pebbles are missing or loose. Count loose pebbles found during cleaning and note patterns of loss. Document whether loss is uniform or concentrated in specific areas.
⚠️ Warning: Don't ignore early signs - pebble loss typically accelerates over time.
💡 Pro Tip: Use underwater camera or snorkel gear for thorough surface inspection.
Identify Loss Patterns and Locations
Note if pebble loss occurs more in high-traffic areas, around fittings, on steps, or follows structural lines. Different patterns indicate different causes - uniform loss suggests chemical issues, localized loss suggests mechanical damage.
⚠️ Warning: Loss following crack patterns indicates structural problems.
💡 Pro Tip: Map problem areas to help identify underlying causes.
Check Water Chemistry History
Review long-term pH, alkalinity, and calcium hardness records. Aggressive water conditions dissolve cement matrix holding pebbles. Look for periods of poor chemistry maintenance or acid washing damage.
⚠️ Warning: Continuing poor chemistry will damage any repair work.
💡 Pro Tip: Bring several years of water test records to professionals.
Evaluate Surface Age and Installation Quality
Determine when surface was installed and by whom. Early pebble loss (under 10 years) often indicates poor installation. Check if proper application techniques and curing procedures were followed.
⚠️ Warning: Poor installation often leads to premature widespread failure.
💡 Pro Tip: Original installation records help identify workmanship issues.
Assess Underlying Structure
Check for cracks, settlement, or movement in pool shell that could stress pebble surface. Look for signs of structural repair or previous patching. Determine if shell issues need addressing before resurfacing.
⚠️ Warning: Surface repairs fail without addressing underlying movement.
💡 Pro Tip: Structural problems must be fixed before surface repairs.
Pebble Loss Repair Options
Repair vs. Complete Resurfacing
Spot Patching (Limited Effectiveness)
When Possible:
- • Very small isolated areas (less than 1 sq ft)
- • Recent damage from known cause
- • Temporary fix until full resurfacing
- • High-traffic spot repairs only
Limitations:
- • Color and texture never match exactly
- • Patches often fail within 2-3 years
- • May accelerate loss in adjacent areas
- • Temporary cosmetic solution only
Complete Resurfacing (Recommended Solution)
When Required:
- • Loss covers more than 10% of surface area
- • Multiple scattered areas of loss
- • Surface is over 20 years old
- • Underlying structural issues present
Benefits:
- • Uniform appearance and texture
- • Addresses all underlying problems
- • 15-20 year lifespan when done properly
- • Opportunity to upgrade surface type
Surface Upgrade Options
Consider alternatives during resurfacing:
- • Newer Aggregate Finishes: Improved durability and colors
- • Glass Bead Finishes: Smoother texture, easier cleaning
- • Quartz Finishes: More consistent color and texture
- • Traditional Plaster: Lower cost, classic appearance
Professional Pebble Resurfacing
Complete Surface Renewal Process

Prevention Tips
Preventing pebble loss protects your significant investment in aggregate surfacing. These practices maximize surface lifespan and maintain appearance.
Maintain Proper Water Chemistry
Keep pH 7.2-7.6, alkalinity 80-120 ppm, and calcium hardness 200-400 ppm. Aggressive water dissolves the cement matrix holding pebbles. Consistent water balance prevents chemical damage to aggregate surfaces.
Gentle Pool Cleaning Practices
Use soft brushes and avoid aggressive scrubbing that can loosen pebbles. Don't use metal brushes or high-pressure washing on pebble surfaces. Clean regularly but gently to prevent mechanical damage.
Professional Startup After Installation
Proper 30-day startup process is critical for pebble surface longevity. Incorrect water chemistry during curing can cause premature failure. Use experienced professionals for new surface startup.
Regular Professional Inspection
Annual assessment of pebble surface condition identifies problems early. Professionals can spot loose pebbles and cement matrix deterioration before major failure occurs.

Frequently Asked Questions
Why are pebbles falling out of my pool surface?
Pebbles fall out due to: poor initial installation, inadequate cement matrix, aggressive water chemistry, structural movement, freeze damage, or normal wear after 15-20 years. Poor workmanship during original application is the most common cause of early pebble loss.
Can loose pebbles be repaired or re-attached?
Individual pebbles cannot be effectively re-attached once they fall out. Small areas can be patched with matching material, but widespread pebble loss requires professional resurfacing. Patch repairs are temporary and won't match the original appearance.
How long do pebble pool surfaces typically last?
Quality pebble surfaces (like Pebble Tec) last 15-20 years with proper maintenance. Factors affecting lifespan: installation quality, water chemistry balance, climate conditions, and pool usage. Pebble loss before 10 years often indicates installation problems.
Is it safe to swim with loose pebbles in the pool?
Swimming with minor pebble loss is generally safe, but loose stones can injure bare feet and damage pool equipment. Large areas of pebble loss create rough, uncomfortable surfaces and should be addressed to prevent further deterioration.
