KEYBAG GEOTEXTILE WEIGHTS
The KEYBAG wrap-around weight is manufactured from a non-woven geotextile chosen for its excellent hydraulic properties, as well as the proven strength of the material and it's long-term durability underground. The KEYBAG weights are available from stock in sizes 4" - 12".
Of the polymers used to manufacture geotextiles, polypropylene exhibits the greatest resistance to chemical attack. In fact, polypropylene is the polymer of choice for such commonly used products as landfill liners, synthetic grass for athletic fields, outdoor carpeting, battery cases, bleach bottles, antifreeze jugs, washing machine agitators, and thousands of other commonly used items that are routinely exposed to chemical environments. Polypropylene is stable within a pH range of 2 to 13, making one of the most stable polymers. Polypropylene geotextiles have been found to be durable in a wide range of chemical environments. Research has found both woven and nonwoven polypropylene geotextiles to be non-biodegradable and resistant to commonly encountered soil-bound chemicals, landfill achates, mildew, and insects.
Lifting and fastening the weight to the pipe is accomplished with web slings, lifting in the "basket" mode. Sling material is a woven polypropylene, resistance to abrasion and excellent resistance to rot and mildew.
Fill material is 1/2" minus aggregate. The choice of this aggregate gives our weights some distinct advantages. First, the fill will not freeze into a solid lump. It will remain easy to install in all weather. Second, the immersed weight of the aggregate is superior to either concrete or sand, so the number of weights required on the line will be reduced.
The filling of the weights can be done at remote locations. If you have a large project and wish to save transportation charges, contact us about custom filling at a site near the right-of-way. If you choose to utilize your own crews, we have available filling tubes for a "bobcat" type quick-connect, and we can train as required. Once you choose us for your weight requirments, our goal is to make your job as easy and as profitable as possible.
