Membrane systems

RENOLIT system selection

Choose by use, finish and detail—not thickness alone.

The correct membrane is coordinated around the pool environment, substrate, traffic, slip-resistance requirements, exposure, geometry and desired appearance. This guide establishes the conversation; final products are confirmed in the project proposal and submittal package.

Selection criteria

What Ferguson Aquatics reviews before recommending a system.

  1. 01
    Facility and bather use

    Municipal, hospitality, rehabilitation, competitive and residential environments place different demands on the surface.

  2. 02
    Substrate and existing finish

    Concrete, plaster, paint, tile and existing membranes require different preparation and transition planning.

  3. 03
    Slip-resistant zones

    Steps, benches, ramps, beach entries, coping and deck areas are reviewed separately from vertical walls and pool floors.

  4. 04
    Geometry and penetrations

    Gutters, drains, returns, rails, targets and specialty fittings drive the detailing package.

  5. 05
    Exposure and appearance

    Indoor or outdoor exposure, water color, pattern, texture and surrounding architecture inform the finish selection.

Project documentation

Selection becomes a written system.

Final membrane, color, texture, accessory materials and detail requirements should be recorded in the proposal or submittal—not left as a verbal field decision.
