Frequently Asked Questions
What is DuraWattle made of, and how does it filter sediment?
- It consists of a plastic-sealed polyurethane foam core and an outer layer of UV-stabilized polypropylene monofilament filter fabric.
- The nonpermeable foam core blocks sediment buildup, while water passes through the fabric filter at the base.
How effective is its filtration performance?
- It offers a clean-water flow rate of approximately 100 gpm/ft² and achieved 96.6 % sediment retention and 58 % turbidity reduction in ASTM testing.
Is DuraWattle durable and reusable?
- Designed for heavy equipment traffic—fully rebounds after vehicles pass over it.
- Can be reused in 70–90 % of installations; lifespan is typically 3–5 years, sometimes longer under favorable conditions.
Will it maintain barrier height under traffic?
- Maintains shape and height when driven directly over; heavy machinery may reduce lifespan if wheels idle or turn on it.
How is it installed?
- On soil or curbs: Dig a 3″ × 6″ trench upstream, place the tail, pin every 4 ft and at section joints, spraypaint pin locations for easy removal, backfill over the tail.
- On hard surfaces: Clear debris, fold tail over a steel strip or wood plank, anchor with 2¾″ concrete screws every 4 ft after drilling pilot holes.
- Sections interlock via fabric sleeves for a continuous barrier.
How long are the sections and how much do they weigh?
- Standard sections for perimeter control, measure 12 ft and weight 5lbs
- 18’ sections optional for driveway sections, wight 7.5lbs
How easy is it to transport?
- 12 sections ships compressed; six 300ft, 100lb bundles (totaling 1,800 ft) fit on a pallet.
- 18’ sections ship in 5 bundles of 360’, 120lb bundles (totaling 1,800 ft) fit on a pallet.
- A 300ft bundle fits in a pickup truck and is light enough for manual handling.
- Once inflated, it occupies more volume but remains lightweight and transportable.
How is it maintained and removed?
- After rain, simply shovel sediment off the upstream side.
- To remove from soil, pull painted pins and lift the barrier; from hard surfaces, remove screws and hardware.
Does it absorb hydrocarbons or metals?
- DuraWattle is not designed to absorb hydrocarbons or dissolved metals; use additional BMPs if needed.
What are its limitations?
- Avoid using it as the sole control on heavily sloped sites with runoff collecting at a single low point; consider adding extra BMPs.
- Repeated heavy vehicle turning or stopping on top can tear the barrier.
- Sites with high traffic may reduce the ability to reuse the wattle.
How do I set up a test sample or get a quote?
- You can request a free sample pack containing two 12 ft sections and a 2 ft sample
- For pricing, contact the company for a customized quote.
