PipeSak bag weights offer a number of advantages over other pipeline weighting systems.

Advantage #1

Economical

Low product price, reduced handling costs, and use of local gravel as ballast combine to make PipeSak the most economical pipeline weighting system.
Advantage #2

Short lead time

PipeSaks can be fabricated and shipped directly to a site, often within days.
Advantage #3

Easy to install

Installation is simple. Fill the PipeSak bag weights with gravel from a local source, distribute along the right of way, lower over the pipeline, and back-fill.
Advantage #4

Easy to store

Leftover PipeSaks can be folded up and put on a shelf until your next project.
Advantage #5

Less weight required

PipeSak's "effective weight" under water often exceeds that of equivalent concrete weights due to less water being displaced.
Advantage #6

Environmentally friendly

Concrete coatings and saddleweights can leach chemicals into the ground water. PipeSak's non-biodegradable polypropylene fabric is filled with local gravel, making them as environmentally friendly as the natural stone used to fill them.
Advantage #7

Trench friendly

No extra trench depth required. Less trench dewatering required. PipeSak conforms to most trench bottoms.

Advantage #8

Better Cathodic Protection

PipeSak is as permeable as the ballast used to fill it, allowing groundwater and cathodic protection an easy path.
Advantage #9

Soft

PipeSak bag weights are a soft buoyancy control, allowing the pipeline the ability to move slightly while still maintaining negative buoyancy and coating protection.
Advantage #10

Easy to remove

PipeSak is non-biodegradable and can easily be removed if ever required.
Comparison

Concrete Weights

Concrete weights tipping
  • long lead time to form and cure
  • trench must be dewatered
  • extra trench depth often required
  • potential for coating damage
  • weight tipping is always a problem
  • leftover weights are common
  • lift hook prone to rusting
  • have been known to leach chemicals into the groundwater

Comparison

Continuous Concrete Coating

The pipe to be handled is now 4 times heavier
  • expensive and heavy - generally used only for river crossings
  • long lead time
  • have been known to leach chemicals into the groundwater

Screw Weights

  • expensive for small projects
  • borehole logs required
  • resistance to rusting and cathodic shielding unproven
  • workers required in trench
  • rigid fix
