Pipesak Bag Weights


Pipesak® Buoyancy Control

PipeSak® is a geotextile pipeline weight that is filled with local aggregate and placed on the pipeline to provide long term buoyancy control. PipeSak® restricts uplift with no risk to the coating and are as permeable as the ballast used to fill them, allowing groundwater and cathodic protection an easy path.

PipeSaks are manufactured from the heaviest grade geotextile in the industry and are rated for underground use. We routinely certify all components – fabric, webbing, and thread – to meet a minimum 4 times safety factor.

Environment and Pipeline Friendly
PipeSaks are a soft method of buoyancy control, allowing the pipeline to move slightly while still maintaining negative buoyancy and coating protection. They allow for the easy passage of water supporting cathodic protection systems. They are non-biodegradable and as environmentally friendly as the natural aggregate used to fill them.

PipeSaks® are easy to transport and install, require no extra trench depth and no trench dewatering, making PipeSak® the most economical pipeline weighting system.

Safe and Durable
PipeSaks® spread the fabric load using a multi-compartment design that is safer and longer-lasting than the one or two compartment design used by other fabric weights.

PipeSak® is the only geotextile pipeline weight with a multi-compartment design that is engineered to evenly distribute the weight. The multi-compartment design improves safety, speeds up installation, and ensures integrity is maintained, even if one compartment becomes damaged.


PipePillo® Pipeline Support

PipePillo® is a high-performance structured pipeline pillow (SPP) designed to permanently support fully-loaded pipelines from the rocky trench bottom. It provides permanent support and is the only engineered solution – replacing foam, sandbags and pad dirt.

Environment and Pipeline Friendly
PipePillos are manufactured from high strength polypropylene resins which are environmentally inert yet softer than pipeline coatings. In addition, PipePillo’s 90 degrees of support limit ovality and their many cavities support cathodic protection systems.

Designed for Strength
The design incorporates a patented dual frustoconical shape which is able to transfer extreme loads very effectively through to consolidated or virgin soil beneath.

Easy to Handle and Install
PipePillos are light enough to be manually handled, yet dense enough to resist flotation.

All PipePillos have a rectangular center hole, which accommodates an installation rod (2×4) for positioned placement without workers in the trench. For deeper excavations, PipePillos can be strapped to the bottom of the pipeline prior to the pipe installation.

Additional Uses
Stringing & Welding
PipePillos were designed for use both in and out of the trench. Outside the trench, PipePillo® is well-suited for use stringing and welding as single or multi-stacked supports. PipePillos are lightweight and can be moved and stacked by a single worker. Reuse PipePillo® on your next project or easily place in the trench for permanent pipeline support.

Integrity Digs
PipePillo® can be used as an effective means to support exposed pipelines during and following integrity digs. Achieve additional height by stacking multiple PipePillos, limiting the requirement for compacted soil beneath the pipe.

Pipe Inspection and Fabrication
PipePillos are excellent for use in the shop during pipe inspection and fabrication. Their versatile and adjustable stacking heights make them an indispensable piece of equipment, offering your pipe a stable resting place and a full 90 degrees of support.

Pipe Storage and Transportation
PipePillo® was engineered to safely hold up to 80,000 lbs and provide a full 90 degrees of support, making it an ideal solution for pipe storage and transportation. Help protect your pipe by limiting ovality, improving drainage, and lowering costs by having a PipeSak® engineer design your pipe storage solution using the versatile PipePillo® product.


RockStopTM  Pipeline Protection

RockStop is the latest innovation in engineered pipeline protection wrap. Designed to protect the pipe by cushioning the impact and abrasion of rocks, it’s high compression, puncture and tear resistant, eliminating the need to import select fill, as the on-site native soil can be used to backfill the pipeline.

Best in Class Pipeline Protection
RockStopTM is flexible for easy handling, even at low temperatures, and is chemically inert ensuring the textile will not rot. The wicking properties of the textile allows for excess water to be removed from around the pipe for cathodic protection.

RockStopTM is up to 50% lighter than traditional stranded rockshields and has faster installation using either RockStop Tape or our RockStop LT Heat Tool

Features and Benefits

  • Impact & abrasion resistant
  • Flexible in hot or cold weather
  • Eliminates the need for selected fill
  • Chemically inert
  • Easy to install
