Frequently asked questions

View all FAQs
  • What is PREFLEX 3000 Detailing Tape used for?
    Compatibility

    PREFLEX 3000 Detailing Tape is a high-performance unsanded double-sided tape engineered specifically for the PREFLEX 3000 pre-applied HDPE sheet membrane system. Used at overlaps, terminations, and vertical-to-horizontal transitions.

  • Why no sand?
    Performance

    The standard PREFLEX 3000 membrane has a sand layer for mechanical interlock with concrete. The detailing tape omits the sand to allow direct bonding at lap edges and terminations - giving the cleanest possible weld at critical joins.

  • Where is it used?
    Installation

    Applied at PREFLEX 3000 sheet overlaps, around penetrations (pipe collars, drains), at the perimeter terminations of the membrane, and at vertical-to-horizontal transitions where two pieces of PREFLEX meet at right angles.

  • Is it compatible with other membranes?
    Compatibility

    PREFLEX 3000 Detailing Tape is engineered specifically for the PREFLEX 3000 system. For other membrane systems use the matched detailing tape from that system (FLEXTAPE for liquid membranes, SA TAPE for sheet detail work).

  • How thick is it?
    Performance

    Double-sided heat-reactive adhesive layer designed for sealed laps in tight areas. Refer to the PREFLEX 3000 installation manual for exact dimensions and roll specifications.
