simple rule
Simple Rule

Wherever there is a construction site, military operation,or just disturbed soil,whenever soil is being moved orequipment is being used on un-sealed surfaces,wind and water erosion as well asdust problems occur.

key figures
Key Figures
  • 6 billion tons of soil washed or blown away each year(exceeding the “Dust Bowl” years of the 1930’s)
  • Constantly 38 million acres at risk to wind or water erosion
  • A total of 1.5 million miles of unpaved roads in the U.S. (53% of all roads)
  • 3.8 million acres of public roads (not including parking lots, farm lanes, private roads, etc.)
what is dust
What is Dust?
  • Small particles (0.5 to 50 µm)
  • Inorganic (sand, salt, stone dust, fly ash, etc.)or
  • Organic (coal dust, grain dust, sawdust, etc.)
sources of dust
Sources of Dust
  • Wind-blown dust from exposed surfaces such as bare land and construction sites
  • Dust caused by vehicle/equipment movement along un-sealed roads
  • Military operations
  • Mines and quarries
  • Roads works
  • Land development (residential, commercial and military)
  • Agriculture and forestry activities
dust problem 1
Dust Problem (1)
  • Human health issues

- irritation in upper respiratory tract with dust particles > 2.5 µm- damage of epithelial cells in lung and potential infiltration into bloodstream with dust particles < 2.5 µm- additional health risks for people that suffer from asthma, bronchitis, emphysema, or other respiratory conditions- potential health problems for infants, children, the elderly and pregnant women.

dust problem 2
Dust Problem (2)
  • Operational issues

- increases safety hazards- additional equipment maintenance- reduces mission success- unnecessary training delays- potential malfunction of electronic and other equipment

dust problem 3
Dust Problem (3)
  • Environmental issues

- contaminates groundwater and edible crops- stunts growth of vegetation- sediments reduce habitat of aquatic life, ultimately affecting the entire food chain- loss of valuable soil

unsatisfactory quick fix 1
Unsatisfactory Quick Fix (1)
  • Water

- extremely short-term solution- must be applied repeatedly to counter evaporation- waste of natural resource- labor intensive- no stabilization capabilities

unsatisfactory quick fix 2
Unsatisfactory Quick Fix (2)
  • Chlorides or Salt Brines

- short-term control- leads to saline contamination of groundwater and death to plant life- causes corrosion of equipment- will wash out with rain - little stabilization capabilities

unsatisfactory quick fix 3
Unsatisfactory Quick Fix (3)
  • Petroleum Products (motor oil, cut-back asphalt)

- minimizes re-suspension of fine dust particles - leads to heavy contamination of groundwater and surface streams- already prohibited in many states

a better solution
A Better Solution

Sustainable, durable, environmentally safe dust suppression and sediment control by application of acrylic polymer technology

proactive approach is preventing the problem at the source
Proactive Approach is Preventing the Problem at the Source
  • Bonds individual soil particles together making them too large to move either by wind or water erosion
  • TSS is minimized
  • PM10 and PM2.5 is significantly reduced
  • Sustainable protection over a considerable period of time
polymers in the erosion control industry
Polymers in the Erosion Control Industry

Two main types used in erosion and soil stabilization industry:

  • Vinyl Acetates (PVAs, VAEs) and co-polymers (mixed blends of emulsions)
  • Latex/Acrylic based emulsions
main drawbacks of vinyl based emulsions
Main drawbacks of vinyl based emulsions
  • Little to no UV-protection
  • Hard to maintain as a hard surface
  • High water absorption (20-40%) even after extended curing
  • Water swollen polymer results in soft and weak film/crust
  • Weaker bond than acrylic films
  • Only short-term effect – no sustainability
how does acrylic polymer technology work for soil stabilization
How does Acrylic Polymer Technology Work for Soil Stabilization?
  • Material Characteristics- Polymer is long chain and high molecular weight material
  • Sustainability- Serves as binder to adhere small dust particles together- Forms flexible and firm surface crust as protection against wind and water erosion- Does not deplete natural resources
  • Safety- As a water-miscible and non-volatile product, once cured, polymer does not evaporate, wash away in rainy conditions, or contaminate the groundwater- It will not leach through the soil
Environmentally friendly

Works with indigenous soil/surface materials

Superior bonding

Sticks to itself

All weather stable

Water insoluble on curing

Non-toxic / non-hazardous



Stops wind erosion

Stops water erosion

Stabilizes surface and/or subsurface

Reduces or prevents pollution

Will not leach out of soil

Available clear or colored

environmental considerations
Environmental Considerations

Acrylic polymers have been proven to be environmentally safe products.

  • Contain no harmful chemical solvents
  • Do not emit any volatile organic compounds (VOC)
  • Are non-corrosive and non-flammable
  • Do not change the pH of the soil
  • Have no harmful effects on people, plants, animals, fish, or other aquatic life
sustainable performance through product additives developed by dirtglue enterprises
Sustainable Performance through Product Additives developed by DirtGlue Enterprises
  • Excellent film-forming properties over a broad temperature range
  • Superb adhesion to fine particles, both inorganic and organic
  • Unusual film strength and flexibility over a wide temperature range
  • Remarkable chemical, thermal and ultraviolet light stability
  • Enhanced hydrophobic characteristics
safety driven applications
Safety Driven Applications
  • Treat roads in battle/enemy zones to minimize dust clouds – making it less easy to track troop movements from a distance
  • Spray application on large areas where dust particle sensitive equipment such as helicopters, aircraft, weapons, etc. is being used or stored – reduces, if not eliminates equipment failures and reduces time consuming, unplanned maintenance
  • Incorporate DirtGlue polymer emulsions into sand or sand bags thereby providing a stable and hardened defense
more applications
More Applications
  • Non-traffic surfaces
  • Light-duty and heavy-duty traffic surfaces
  • Fuel and ammunition supply routes
  • Helicopter landing pads
  • Road/Trail intersections
  • Bivouac areas
  • Temporary aircraft taxiways
  • Training grounds
  • Field compound areas
  • Temporary aircraft runways (new or expansion)
  • Hardened revetments (more permanency)

cost effectiveness
Cost Effectiveness
  • Long-lasting effectiveness of individual acrylic polymer applications compared to traditional practices
  • Efficient application procedures that provide improved productivity of personnel/labor force
  • No special equipment (read: investment) needed for successful applications. Standard construction/landscaping equipment sufficient.
  • Environmental compliance reduces risk of penalties or costly delays on construction sites

Further Product Developments based on Acrylic Polymer Technology
  • Pot hole repair in connection with DirtGlue Catalyst that allows applications at low temperature and provides fast curing
  • Coal pile / ash stabilization
  • Concrete Sealer
  • Fugitive dust and erosion are some of the most pressing problems on any disturbed soil in the United States
  • Traditional practices produce only limited success and short-term effect
  • Acrylic Polymer Technology is a base for superior solutions
  • DirtGlue polymer additives and refined application technology yield sustainable performance and safety
  • New Technology is cost competitive compared to traditional practices
  • A variety of additional applications are being developed
