FAQ

  • What is rockshield for pipelines?

    A rockshield is a protective layer made from flexible geotextile or plastic mesh that wraps around pipelines. It prevents damage from rocky backfill and protects the pipeline coating during installation.

  • When should rockshields be used?

    Rockshields should be used when burying pipelines in rocky or abrasive soil conditions to prevent coating damage and extend pipeline lifespan. They are especially useful in high-impact areas where rocks or debris may shift over time.

  • What is RockStop® Rockshield made from?

    RockStop® rockshield is a geotextile fabric. This rockshield is specially formulated with UV-resistant materials to ensure pipeline protection in a wide range of construction environments. RockStop® rockshield is routinely tested to ASTM standards and is manufactured in ISO:9001 rated North American facilities to guarantee its strength, durability and longevity.

  • What sizes can RockStop® Rockshield be purchased in?

    RockStop® rockshield is available in rolls and pads convenient for every size of pipeline and can also be custom cut to order. RockStop® rockshield can also be purchased in ‘Master Rolls’ for longer stretches of pipeline requiring protection from rocks. For a chart of all available and stocked sizes, please request a product brochure.

  • Do you rent or sell the bars used to install the larger sized rolls?

    Both! Contact a PipeSak® representative for more information.

  • How are rockshields installed on pipelines?

    Rockshields are wrapped around the pipeline before backfilling and secured using cable ties, filament tape, or adhesive strips, depending on the type. They are lightweight and easy to install, making them an efficient solution for pipeline protection.

    RockStop® Rockshield offers faster installation compared to traditional rockshields, thanks to its innovative attachment methods:
    • QuickStrips™ – A Velcro-like seal designed for superior shear and peel strength, ensuring a secure fit.
    • Heat Welding– Using the RockStop® heat tool, creates a permanent, pipeline-safe seal in seconds, without damaging the pipeline coating.

  • Are rockshields compatible with cathodic protection?

    Yes, rockshields are designed to be permeable, allowing cathodic protection (CP) systems to function properly. Unlike some protective layers, rockshields do not create a barrier that interferes with electrochemical protection.

    While RockStop® rockshield provides full coverage all-around protection blocking out sand, stones, and rocks up to 8”, it is designed to allow water to pass through it to and away from the pipe ensuring it does not shield CP systems.

  • Does the RockStop® Rockshield hold moisture against the pipeline coating?

    RockStop® rockshield permeability is designed to react similarly to the surrounding soil and will dry out as the soil does so it won't swell and works well with cathodic protection systems allowing groundwater to and from the pipe. After backfilling, RockStop® rockshield will dry out as quickly as the surrounding soil. RockStop® rockshield hydrate conductivity is similar to sand.

  • What level of impact protection do I need?

    RockStop® not only passes the ASTM G13 modified test up to 6” rock but also passes the test with 8” rock- making RockStop® the best-performing rockshield on the market for impact protection while remaining lightweight, soft to the touch and the safest to install, needing no workers on the ditch side.

  • What type of Rockshield should I use?

    Choose a rockshield that can be easily modified in the field and custom cut to minimize waste and save money.

    RockStop® rockshield is available in large master rolls to can be applied to a long stretch of pipeline at once or as easy-to-use and handle custom cut pads for your desired O.D. RockStop® pipeline rockshield can also be trimmed in the field and easily manipulated in any weather for quick application.

  • What is the lightest weight rockshield available?

    RockStop® weighs 0.41 lb/ft² maximum, making it lighter than any traditional rockshield. This lightweight design allows for easier handling and installation without compromising on protection.
