      Rebar connections are completed by injecting or pouring nonshrink grout into the sleeve, a process that takes only seconds, significantly reducing labour time and site costs.

    • Fast OnSite Installation

      Rebar connections are completed by injecting or pouring nonshrink grout into the sleeve, a process that takes only seconds, significantly reducing labour time and site costs.

    • Compatible with Standard Grouts

      The coupler works with commonly available nonshrink grout brands such as Sika, Davco, Fosroc, and BASF, so contractors don’t need to source specialised or expensive materials.

    • Simplified Procurement and Logistics

      With minimal tool requirements and compatibility with standard grouts, Groutec F streamlines procurement and reduces supply chain complexity, lowering indirect project costs.
  • Bracing: three days only
    • After the sleeve is filled with non-shrink grout, the temporary bracing used to support the precast element can typically be removed after approximately three days.
    • This curing period allows the grout to develop sufficient strength, ensuring a stable and reliable connection between the precast elements.

Equipment features & benefits

  • Engineered, tested and compatible with major non-shrink grout brands easily available on the market: Sika, Parex-Davco, Fosroc, BASF and Pozament. Reduce overall cost and simplify sourcing.

  • Cost Effective

    Dextra Groutec Large coupler (Groutec L) is considered cost-effective in many precast concrete projects, mainly because it reduces labour, installation time, and sourcing costs.

    Here are the main reasons why Groutec L is cost-effective:

    • Faster Installation on Site

      The connection is made by injecting non-shrink grout into the coupler cavity, which can take only a few seconds. Faster installation means less labour time and lower site costs.

    • Reduced Construction Time

      After grouting, temporary bracing can often be removed after about three days, helping accelerate project schedules and reduce equipment and labour costs.

    • Uses Standard Non-Shrink Grout

      The coupler works with commonly available grout brands, so contractors do not need expensive proprietary materials, which reduces procurement costs and simplifies sourcing.

    • Large Alignment Tolerance

      Groutec L has a wide cavity that tolerates rebar misalignment, making installation easier and avoiding rework during precast element assembly.

    • Higher Productivity in Precast Construction

      Because installation is quick and alignment tolerance is large, precast elements can be erected faster, improving overall construction productivity.

    • Reduced On-Site Labour

      The system requires only screwing the threaded bar and grouting, eliminating complex on-site processes and reducing labour requirements.
  • Bracing: three days only
    • After the sleeve is filled with non-shrink grout, the temporary bracing used to support the precast element can typically be removed after approximately three days.
    • This period allows the grout to develop sufficient strength, ensuring a stable and secure connection between the precast elements.

Equipment features & benefits

  • Engineered, tested and compatible with major non-shrink grout brands easily available on the market, reducing overall cost and simplify sourcing.
  • At the precast factory, fast and precise installation thanks to Groutec L threaded end. Take advantage of the full range of accessories available to simplify your precasting process.
