How to Prevent PVC Membrane Failure in Commercial Pools

How to Prevent PVC Membrane Failure in Commercial Pools

Commercial pools face far more demanding conditions than standard residential pools. Constant UV exposure, aggressive sanitation systems, elevated water temperatures, and high bather loads can all accelerate membrane wear if the right materials are not used. Premium solutions from Poolside by CGT, including Infinity Pool Surface and Aquasense Signature PVC membranes, are engineered to improve fade resistance, chemical resistance, and long-term durability in harsh swimming pool environments. 

For installing contractors, membrane performance depends on both material quality and proper installation practices. High performance reinforced PVC membrane systems can help reduce callbacks, minimize maintenance concerns, and protect the long-term appearance of commercial swimming pools.   

This checklist outlines the most common causes of membrane failure in commercial pools and how premium membrane technologies like Infinity Pool Surface and Aquasense PVC membranes can help prevent costly issues over time.  

Step 1: Start with Proper Surface Preparation  

A poorly prepared pool substrate can create stress points that lead to wrinkles, punctures, and premature wear. Proper preparation is essential when installing Infinity and Aquasense membranes from Poolside by CGT to help maximize waterproofing/finish durability and long-term performance in commercial pools.

Quick Checklist   

• Ensure the pool shell is smooth and level   

• Remove all debris and sharp edges   

• Check corners, steps, and ledges carefully

• Verify moisture control before installation   

• Confirm all base materials are fully cured

• Check all termination areas for surface integrity 

Step 2: Follow Best Installation Practices  

Even PVC membrane systems can fail prematurely if installation shortcuts are taken. Proper installation techniques are critical for maximizing the performance of Infinity and Aquasense membranes from Poolside by CGT, helping prevent wrinkles, seam separation, and early liner wear in luxury pool and commercial environments.   

Quick Checklist   

• Install within recommended temperature ranges   

• Set wall and floor membrane orientation correctly    

• Protect the membrane from sharp tools and debris   

• Follow proper heat welding techniques   

• Thoroughly check, probe, and seal all seams

Step 3: Balance Water Chemistry Immediately

Improper water chemistry is one of the fastest ways to damage vinyl liners and PVC membranes in commercial and luxury pools. Maintaining balanced water is essential for protecting Infinity commercial pool surfaces and Aquasense 3-ply membranes from Poolside by CGT, helping improve chemical resistance, reduce fading, and extend long-term liner durability.

Quick Checklist 

• Test chemistry before startup 

• Avoid excessive chlorine levels 

• Prevent direct chemical contact with the membrane

• Monitor automated feeders regularly 

• Train staff on vinyl-safe maintenance practices 

Recommended Targets  

Early Warning Signs of PVC Membrane Failure 

Watch for these signs before minor damage becomes a full replacement project:  

• Fading or discoloration  

• Wrinkling or floating sections  

• Brittle texture  

• Seam separation  

• Waterline staining  

• Cracking near fittings  

• Persistent leaks  

Identifying problems early can reduce downtime and repair costs.  

Choosing the Right Premium PVC Pool Membrane

Not all liners are designed for luxury residential or commercial-grade pool performance. Infinity and Aquasense membranes from Poolside by CGT are engineered to deliver enhanced durability, fade resistance, and chemical protection in harsh pool environments. 

Look For  

• Enhanced fade resistance   

• Strong chemical resistance   

• Reinforced seams   

• UV-stabilized coatings   

• Commercial-grade thickness options   

• Saltwater compatibility   

• Reliable manufacturer warranties
