Residential pool membranes

Not every “liner” is built the same.

Ferguson Aquatics offers reinforced PVC membrane for select residential renovations where a field-welded waterproofing system provides a better fit than a conventional replacement vinyl liner.

Reinforced versus conventional

A membrane system—not a factory-made bag liner.

Traditional residential vinyl liners are commonly manufactured in the 20–30 mil range and fabricated offsite to fit a measured pool. They remain a practical finish for many purpose-built vinyl-liner pools.

Reinforced PVC membrane is a different assembly. RENOLIT membranes combine flexible PVC layers with internal polyester reinforcement and are typically supplied in heavier 60–80 mil classes. The material is fitted and heat-welded at the pool, allowing the installer to build around the actual shell and its details.

Side-by-side

Two products with different construction and installation methods.

CategoryReinforced PVC membraneTraditional vinyl liner
Construction

Polyester-reinforced PVC laminate

Unreinforced vinyl liner material

Typical thickness

Approximately 60–80 mil, depending on the selected system

Commonly approximately 20–30 mil

Fabrication

Cut, fitted and heat-welded onsite

Factory-fabricated to the pool measurements

Installation approach

Applied as a waterproofing surface over a prepared compatible shell and protection layer

Hung from liner track and supported by water pressure against the pool structure

Complex details

Field-formed around steps, benches, sun decks, curves, fittings and custom transitions

Built into the ordered liner pattern and measured configuration

Repairability

Individual areas and seams can often be field welded when conditions permit

Patches may be possible, but larger changes commonly require a replacement liner

Thickness alone does not determine performance. Product selection, shell condition, preparation, water chemistry, installation quality and the pool’s intended use all matter.

Where reinforced membrane fits

A strong option for unusual or demanding residential renovations.

Completed Chicago residential pool with patterned RENOLIT reinforced PVC membrane

Chicago, Illinois

444 square feet. Completed in two working days.

This residential transformation used an 80-mil patterned RENOLIT membrane over the specified protection layer, with custom field detailing at the sun deck, steps and skimmer flange.
