KODIAK DIRT BAGS
Dirt bags are used to remove as much sediment as possible from storm water or site discharge from
excavation pumping. They are portable and easy to use by one person eliminating high mobility and
service charges. Our dirt bags are designed to be used with or without flocculants and are custom made
to order (often same day) in our Langley, BC facility. The bags are manufactured using GTX 150
filtration cloth), The apparent opening size in combination with high strength and flow rate make this the
best filtration bag around. The bags are custom cut and assembled using a single seam stitch with a
second stitch on the seam fold. This ensures that material does not escape at the seam as it does with
other single stitched bags on the market. Producing our bags on site gives us the ability to vary material
and shape of the bags to ensure maximum life and minimum footprint on your site.

Tigerfloc belts & kodiak dirt bags
A new water treatment alternative that is being used very successfully on many construction sites now is the combination of a Tigerfloc Belt placed inside of a mixing tube, which then empties out into a micro-pored dewatering bag. The Tigerfloc Belt and Dewatering Bag Unit works well almost immediately filtering out almost all of the sediment from the discharge water.
The Tigerfloc Belt and Dewatering Bag Unit has proven useful in all soil types: sand, silts, and even clays. Many case studies of water passing over the Tigerfloc Belt and then through the Dewatering Bag - results: incoming water measured at >1000 NTUs dropped to under 25 NTUs.
Another option on sites that already have a sediment control pond (still exceeding the allowable discharge limits), is to re-circulate the pond’s water through the Tigerfloc Belt and Dewatering Bag Unit and then empty the clean water into the sediment control pond prior to it discharging down the drain pipe. By re-circulating the water over the Tigerfloc Belt, it will help speed-up the process of sedimentation.
The Tigerfloc Belt and Dewatering Bag Unit is extremely effective, is mobile, has a small footprint on site (approximately 20’ x 20’), and is much cheaper than other alternatives which may compete with these results. It is something to think about the next time you have a site where there might not be enough space for a sediment pond, and you don’t require something as heavy-duty (or as expensive) as a mechanical ‘pump-and-treat’ system.
