Bulk Bag 3000

Our BULK bags are constructed using heavy-duty, UV treated woven polypropylene. The fabric weight (6.5 oz.) is tailored to meet required tensile strength and Safe Working Load (SWL) requirements up to 3,000 lbs. with a Safety Factor of 5-1. To prevent material escape, extrusion coating and seam dust-proofing options are available upon request.

FIBCs (Flexible Intermediate Bulk Containers) are assembled in three standard construction styles:

  • U-panel [one long “U” shaped panel with two side panels attached]
  • Circular Woven [tubular bag, loom-woven, with bottom panel attached-fewer seams mean less particle entrapment]
  • Baffle [polypropylene corner baffles sewn across inside corners of bag to maintain shape rigidity-takes up less volume/easier to stack]

Filling Options:
Duffle Top Spout

Discharge Options:
Bottom Spout-Single Closure

Geotextile Dewatering Tubes

Typical Applications:

  • Dewatering Sludge & Soils
  • Filter Bags
  • Beach Revetments
  • Dike Construction
  • Artificial Reefs
  • Groin Construction

Dewatering Tubes are designed to replace expensive retention basins and to hasten the dewatering process.

Large tubes manufactured of high strength polyester or polypropylene geotextile fabric are hydraulically filled with a dredge or pump. The tubes can be filled with any material capable of being transported hydraulically. The filled geotextile tube assumes a cross section, which is circular on the edges and flattened on the top.

It is possible to fill the tubes to 70 – 80% of their circular diameter, though 50 – 60% is common. Tubes are filled via injection ports. Smaller pumped water filter bags typically have only one injection point whereas larger dewatering tubes have many more fill ports along the top centerline. These ports are used for both filling and for the relief of excess water.

After bulk dewatering occurs, self weight consolidation and confining pressure of the geotextile tube fabric itself continues the dewatering process. Extremely short dewatering time vs the typical retention pond is a result of this process. Also, the retention of odors, pollutants and very fine particles is a typical result of geotextile tube dewatering. Part of the efficient retention process occurs because of the physical properties of the tube fabric(s) and also from the filter cake that forms on the inside of the fabric sell, thus creating a two stage filter.

Brockton Equipment/ Spilldam’s spiral stitch technique used on it’s high strength geotextile tubes greatly improves the overall strength of the dewatering tube. This is accomplished by reducing the pressure on stitched seams and by increasing the circumference strength through the formation of a reinforcing spiral belt formed by the spiral stitching process.

Standard Dewatering bag: 15 ft x 15 ft with (1) injection port

Custom Dewatering Tubes can be manufactured up to 200 ft long by 30 ft diameter with multiple injection ports.

Lighted Buoys

These buoys are sometimes required in navigable water ways to prevent vessel traffic from entering a boomed area. Each buoy is topped with a battery operated flashing light (colored lenses are also available) which is controlled by a photo sensor to come on at dusk and go off at dawn. Lighted buoys would typically replace marker buoys.

Rode and Scope

The rode is comprised of an anchor chain which is attached to the anchor (used to ballast the line) and the rope or line that attaches to the mooring buoy.

Scope is simply the length of the rode. An anchor holds best when the anchor shank is as close to horizontal as possible. The minimum recommended scope is 5 to 1 or 5 times the depth of the water. The ideal scope is a ratio of 7 to 1. By increasing the scope you can increase anchors holding power.
