Let te r o f In t roduc t ion

Soilworks®, LLC is the innovator and manufacturer of Powdered Soiltac® soil stabilizer and dust control agent. Powdered Soiltac® is an eco-safe, biodegradable, dispersible dry powdered copolymer used to stabilize and solidify any soil or aggregate as well as erosion control and dust suppression. Soilworks’® recent advances in simulation, chemistry, processing techniques, and analytical instrumentation have allowed a whole host of new types of polymer particles and polymer nanotechnology applications to be realized. These advances led to the revolutionary development of nanotechnology into Powdered Soiltac’s® superior performance. As a powder, Powdered Soiltac® can be applied by either broadcasting the dry powder topically or mixing it into the treatment area and simply adding water over the site. Alternatively, Powdered Soiltac® can be pre-diluted into a liquid and applied in a similar manner. Powdered Soiltac® is designed to quickly hydrate into a solution that works its way throughout the aggregate or soil particles. Once applied to the soil or aggregate, the copolymer molecules coalesce forming bonds between the soil or aggregate particles. The key advantage of Powdered Soiltac® originates with its long, nanoparticle molecular structure that link and cross-link together. As the water dissipates from the soil or aggregate, a durable and water resistant matrix of flexible solid-mass is created. Once cured, Powdered Soiltac® becomes opaque, leaving the natural landscape to appear untouched. Powdered Soiltac® results are based on the application rate used. Modest application rates are useful for dust suppression and erosion control by creating a three-dimensional cap or surface crust. Heavier rates can generate qualities similar to cement; useful for soil solidification and stabilization found in road building. By adjusting the application rate, Powdered Soiltac® can remain effective from weeks to several years. Most importantly, Powdered Soiltac® is a truly biodegradable product that is completely environmentally safe to use. Powdered Soiltac® has been rigorously evaluated and its performance verified by the U.S. Army Engineering Research and Development Center (ERDC) against the industry’s traditional top performing soil stabilizers and dust control agents. As a result, the Department of Defense continues to award Soilworks® with contracts to supply Operation Iraqi Freedom, Enduring Freedom and the on-going Iraq rebuilding efforts with Soilworks® products. Its success with the U.S Military and Allied Forces has led to Soilworks® GSA contract (# GS-07F-5364P). Powdered Soiltac’s® advanced nanotechnology is modernizing the way we stabilize soils and aggregates in addition to controlling dust and erosion for a whole new generation. Powdered Soiltac® applications are extensive ranging from simple backyard trails and construction sites to heavy-lift military cargo runways and global transportation infrastructure. Soilworks® is dedicated to economically solving soil stabilization challenges throughout the world's residential, commercial, industrial and military markets.

**Dilution rates for mix-in/processed applications are based on the difference between optimum moisture (OMC) and in-situ moisture levels. Please consult with your local Powdered Soiltac® representative to calculate recommended dilution rates for all mix-in applications.

Application coverage and dilution rates may vary depending on traffic volume, load bearing capacity, soil type, weather conditions, soil moisture levels and compaction. All Mixed-in/Processed applications require laboratory and on-site testing to determine optimal application and dilution rates.

Powdered Soiltac®

Powder 6 ” (15cm) Mix - In So i l S tab i l i za t ion App l i ca t ion Overv iew 1.) Prepare the Site:

Dry Soil: The site and must be at or below the optimum moisture level. Completely dry is optimal. Weather: The site must be free from rain for a minimum of 72 hours after the application. Temperature must be at 40°F (4°C).

2.) Scarification: Scarification: Scarify, till, disc or manipulate the soil (without clods) to the recommended 6” (15cm) depth. Large Aggregate: Remove any large aggregate (4”+/10cm+) that could effect the final compaction.

3.) Prepare the Powdered Soiltac® Application Equipment: Distributor: Set the powder distributors’ spreader rate to the desired width, height and output rate. Coverage: The powder distributor should provide an even coat over the treatment area with each pass. Spread Rate: Set the spread rate high enough to allow even coverage with multiple coats and low enough to prevent airborne dust.

4.) Apply and Process the Powdered Soiltac®: Application: Apply the Powdered Soiltac® evenly over the scarified treatment area.

Example: 6” (15cm) Deep Base Stabilization Average Rate (5 ft²/lb. = 275ft²/bag) (1.63L/m² = 26m²/bag), 2,145 lbs. (975kg) (39 Bags = 1 Pallet) Powdered Soiltac® X 5 ft²/lb. = 10,725 ft² (1,014 m²) Treatment Area.

Processing: Till, disc or manipulate the treated soil until the Powdered Soiltac® is uniformly distributed into the soil.

5.) Prepare the Water Application Equipment: Water Volume Calculation: The amount of water required to achieve optimum moisture must be field determined by comparing the

in place moisture content to the optimum moisture content (OMC) (determined by a laboratory proctor test ASTM D2216-92). The in place moisture content can be determined by the average of four in place readings with a nuclear density gauge. Testing the native soil for OMC is required to accurately determine the appropriate volume of water to achieve OMC properly. Not enough water will generate dry spots / too much water will create mud or “pumping”. Optimum moisture is critical when compacting for maximum compressive strength. Example: 6” (15cm) Deep Base Stabilization Average Application Volume = ½ft. X 10,725 ft² = 5,362.5 ft³ (498 m²) Proctor Test Maximum Dry Density = 136.1 lbs/ft³ (2,180 kg/m³) Proctor Test Optimum Moisture Content (OMC) = 7.0% (by weight) In-Place Moisture Content = 3% (by weight) Water Density = 8.345404 lbs/gal. (1.000028 kg/L) Calculation: 7% - 3% = 5% Moisture needed to achieve OMC 5% of 136.1 lbs/ft³ = 6.805 lbs/ft³ (109 kg/m³) 6.805 lbs/ft³ X 5,362.5 ft³ = 36,492 lbs (16,552 kg) of water 36,492 lbs (16,552 kg) of water / 8.345404 lbs/gal. (1.000028 kg/L) = 4,373 gal (16,554 L) of water

Water: Fill the application equipment with the necessary volume of water. Spray Nozzles: Set spray nozzles to the desired width, height and output rate. Test equipment (off-site) if necessary. Coverage: The spray nozzles should provide an even coat over the treatment area with each pass. Spray Rate: Set the spray rate high enough to allow even coverage with multiple coats and low enough to prevent water from

draining away from the treatment area.

6.) Apply and Process Water into the Powdered Soiltac® Treatment Area: Application: Apply the water evenly over the Powdered Soiltac® treatment area. Processing: Till, disc or manipulate the treated soil until the water is uniformly distributed into the soil and OMC is achieved.

7.) Grade and Compact: Grading: Contour, shape and crown the site to provide for proper drainage (recommend 2% to 4% minimum). Compaction: Compact the site to a minimum of 95% (per ASTM D 698 D 1557 modified Proctor Density) while maintaining OMC.

Optimally, use a pneumatic (rubber tire) compactor for initial compaction to prevent soil adhering to the drum followed by a vibratory smooth steel drum compactor and finalized without vibration (static compaction/roll).

8.) Clean the Application Equipment:

Rinse: Rinse off all application equipment thoroughly with water until clean. If Powdered Soiltac® is allowed to dry and cure, use a hot pressure washer or steam cleaner and brush to remove residue.

Traffic: Prevent any human activity over the treated area until the site has completely cured. Curing: Allow the treated area to dry and cure for approximately 24 hours (@70°F/21°C). Topical Wear Coarse: If the mix-in/processed area is not going be covered with an alternate topical wear coarse (example:

asphalt, concrete, chip-seal, etc.), then a topical application of Soiltac® or Powdered Soiltac® must be applied as a topical sealer and surface wear coarse (see our “Standard Application Coverage Rates” for details).
